Pentax Optio S5z
In the case of the £198 Optio S5z, the main feature distinguishing it from the virtually identical S5n is its big 2.5in monitor. To accommodate such a big screen on such a small camera the case has been partially redesigned and is 3mm taller and 1mm thicker than its predecessor, but the size and position of the lens, flash, AF illuminator and self-timer indicator are unchanged. The extra height comes from the curvature of the previously flat top panel, but the positions of the on/off button and shutter release are identical to the previous model.
The only other real difference is that where the S5n has a charging cradle that also accommodates a spare battery, the S5z has a separate battery charger. It doesn’t have the charging contacts on the base, and because it is slightly thicker it doesn’t fit into the old cradle anyway.Because of the big screen, the control layout on the rear panel is rather cramped compared to the elegant design of the S5n. The D-pad menu navigation control is very small and a somewhat fiddly to operate, as is the small rocker switch controlling the zoom lens. Nonetheless the controls are solidly mounted and operate with a nice positive click when pressed, so the camera is actually not unpleasant to use.
There isn’t much room for your thumb, but what room there is has a textured rubber grip and a small ridge, so holding the camera is quite comfortable, even for those with large hands. Build quality is as good as ever, with a strong all-metal case and a secure sprung hatch for the battery and memory card. The battery has a separate catch, so it won’t fall out while you’re changing the memory card.The monitor screen itself is certainly big, and looks bigger thanks to the relative size of the camera, but at 110,000 pixels it’s not especially high resolution. This is the same pixel count as the 2in screen on the S5n, so there doesn’t seem to be much advantage to the bigger screen. It could also do with some sort of automatic brightness control, because it is difficult to see in bright sunlight without increasing the screen brightness in the menu.
Other than the minor differences already listed, the specification of the S5z is identical to that of the S5n. It has the same comprehensive and easy to use menu system, and the same green button. This is a common feature on Pentax compacts, and can be programmed with one of three functions; an easy “auto everything” shooting mode, a quick start for initialising the recording mode, or the more useful Function setting, which assigns a selection of frequently used menu options as secondary functions on the D-pad, including recorded pixels, image quality, white balance, AF area, metering mode, exposure compensation, and adjustable sharpness, saturation and contrast. This allows the user to customise the controls of the camera, and gives it a welcome versatility not often found in budget compact cameras.The S5z has the same 16 scene and shooting modes as the S5n, including night scene, landscape, portrait, self-portrait, sunset, food, pets, text copying, sports/action and beach/snow. It also has a special effects mode that includes soft focus, posterisation, stretching/compressing the image, and adding a white border at the bottom of the frame for a caption or label. Other functions include two-level macro focusing (6cm or 18cm), manual focusing, infinity focusing and pan-focusing, which gives the maximum possible depth of field for wide-angle shots.
Also available are a time-lapse movie mode and colour filters that can be added in playback mode after the shot has been taken. Other playback options include cropping and resizing, copying, brightness adjustment, movie editing and DPOF print ordering. You can also select one of your shots to be used as the start-up screen. For a camera in this price bracket, the range of features offered by the S5 models is extremely impressive. The only things missing are manual exposure options, but with the range of shooting modes available they are not really necessary.
Talking about start-up brings us onto performance. Like the S5n, this camera starts up in approximately three seconds, and in continuous shooting mode it can capture approximately one shot every two seconds at maximum quality. Lowering the image quality slightly increases the shooting rate to about one shot a second. This isn’t particularly fast by recent standards, and as I have mentioned before it is something that Pentax needs to address in its next series of compacts. The autofocus system is extremely quick so there is no appreciable shutter lag, and thanks to the AF illuminator it can focus in complete darkness at a range up to a few meters.
In terms of picture quality the S5z is a solid performer, although it does have a few minor problems. Exposure, focusing and colour reproduction are first-rate, and noise control is especially good. As with the S5n there is no visible noise at 80 or 100 ISO, and only a little at 200 ISO. Some noise is creeping into the shadows at 400 ISO, but images are still completely useable.The only real problems are associated with Pentax’s versatile but now aging Sliding Lens System. Lens distortion has been an issue for this lens from the beginning, and it rears its ugly head here too. On many shots there is slight but noticeable blurring towards the corners of the frame, most obviously on wide-angle and macro shots. It’s not a major problem, but does mar the performance of an otherwise excellent camera.

Verdict












Main mode selection is via a knurled wheel on the back panel above the monitor screen. Available modes are program auto, manual exposure, night shooting, picture mode (scene programs), movie mode, sound recording and a user-defined setting.
Creativity is further enhanced by a good range of focus modes, including manual focus and selectable 5-point AF. Most importantly there is also an extremely good and easy-to-use manual exposure mode with shutter speeds of 4 to 1/1000th seconds and full aperture control from F2.8 to F8.0. This well-thought-out range of creative features and options sets the SVi apart from mere snapshot cameras and actually turns it into a useful creative photographic tool.

The size of the body is mainly to accommodate the power source. Like the S45 and S50, the S55 runs on two AA batteries, making a good choice for holiday photography. If you’re stuck in the middle of nowhere and can’t find a power point to plug in your battery charger, you can always chuck in a couple of Duracells to keep shooting for another few hours.
The control layout is simple enough, but this is not a simple camera, and I would certainly not recommend it for a first time user. My parents, both in their 70s, took the S55 on holiday to Italy to get me some good test shots. My father is a keen amateur photographer and owns a couple of nice film SLRs, but he had never used a 
The plethora of modes and options listed above at least offer some versatility, and it has some features that are a lot of fun to play with, such as colour mask filters that shoot a black and white picture but with one primary (red, green or blue) in colour. Unfortunately the S55 lacks a real manual mode, but the “Fn” button does allow rapid access to exposure compensation, so some quick creative control is available.
In normal light the multi-point AF system is reasonably quick, taking well under a second to lock on, but the lower the light levels the slower it gets, and quickly gets to a point where it won’t lock at all. The camera has no AF illuminator, so you can expect some very blurry nighttime shots.
The Optio WPi is of course based on the popular Optio WP launched about this time last year. Jalal reviewed it here in April 2005 and gave it very high marks. I reviewed it for a certain well-known camera magazine and was also most impressed by it. The new WPi adds an extra megapixel to the existing formula, resulting in a 6MP compact with a 3x optical non-extending zoom lens and a 2in LCD monitor – and let’s not forget that it can also take photos at up to 1.5 metres underwater. It manages to do all this while still being one of the slimmest and most stylish
The controls are nicely laid out, and are broadly similar to those on Pentax’s more mainstream compacts, including the idiot-proof Green Mode button. Most common options such as flash mode, self-timer, drive mode and macro mode are accessed as secondary functions on the D-pad, as are the shooting mode options. These include the usual portrait, night scene, landscape, sports and beach/snow modes, but also include flowers, candlelight, kids, pets, soft focus and an underwater mode. Yet more are available via a customisable menu. Also on the same menu is the movie mode and sound recording. Pressing the green button in this menu brings up a handy note explaining each function for beginners.
The 9-point AF system is not the fastest I’ve ever seen, but it is certainly one of the best for low-light performance. In fact the WPi focuses more quickly, accurately and reliably in lower light than some cameras that are equipped with AF illuminators, a feature which the Pentax lacks. For low light photography the built-in flash has a range of 3.1 metres at wide angle or 2.5 metres at full zoom.
In order to keep the number of potential water ingress points to a minimum, the DC power input and USB connectors are concealed under the locking battery/card hatch, which has a waterproof rubber seal. It comes supplied with a separate battery charger, and uses the same D-LI8 3.7V 710mAh lithium-ion battery as all of the other compacts in Pentax’s range, so if you already own a Pentax the batteries are interchangeable. The D-LI8 isn’t a particularly large battery, and I found that by the end of a long day’s shooting it was down to one bar and in need of a recharge. If you’re taking the WPi on holiday even for a weekend, don’t forget the charger.
With the WPi performing generally well, the movie mode is a bit of a let-down. It is only capable of shooting at 320 x 240 pixel resolution at 30 frames per second with sound, a rather sub-par performance when compared to recent compacts from other leading manufacturers. It does however offer some movie editing options in playback mode, as well as options for still images including colour filters, adjustable brightness, red-eye removal, resizing, and some truly heinous frames that can be added to your pictures, including a lace-trimmed heart shape. Lovely.

Over the past three years, the six consecutive models that have comprised Pentax’s Optio S range of tiny sub-compact
This change has appeared in the form of the Optio S6, the latest in the series. Competitively priced at £229.99 on the high street or as low as £189.99 online, at first glance it looks very much like all the other cameras in the S series. It is extremely compact, with the same well made all-metal body and flush fitting lens. It even has the same concentric circle texture on the front panel. However, although the S6 looks quite similar to its immediate predecessor the S5z, it is a very different camera both inside and out. It still has a 3x optical zoom lens that folds into itself leaving a camera just 19mm thick, but this isn’t the same lens as on previous models. It is a new design which is smaller, lighter and extends much more quickly at power on. Previous Optio S models have been getting a bit slow on the start-up, but thanks to the new lens design and an improved power system, the S6 now takes just 2.5sec to power up. There are a few faster cameras around, but this is better than most.
Another familiar looking feature is the big 2.5in LCD monitor, but this too is vastly improved. It is low-reflection with exceptionally high 232,000 pixel resolution and a particularly fast refresh rate, which means that the scene you see on the monitor doesn’t lag behind movements of the camera.
There are plenty of focusing options to chose from, with pan focus, infinity focus and 25-step manual focus available, as well as macro mode although with a minimum range of 15cm this is not terribly impressive. The focus area mode can be selected in the menu, but sadly the frame-wide selectable AF point is no longer an option, but it has been replaced with an active tracking AF, ideal for shooting moving subjects.
Inside the S6 is a new 6.36MP CCD sensor (6.0 effective), as well as a new faster exposure and autofocus system. It is also equipped with an AF illuminator, which I found would provide a focus lock in total darkness at a range of about 3 metres.
The *ist DL2 is the very epitome of the entry-level DSLR, and that includes the price. It is available exclusively from Jessops, so there are no dubious online discount deals available, but even so it is priced at an incredibly competitive £349 including a high quality 18-55mm f/3.5-5.6 Pentax DA lens. Compare that with £393 for the Nikon D50 or £485 for the (8 megapixel) Canon EOS 350D with similar sized lenses and the DL2 looks like a very tempting package.
With such a small camera there is of course the danger that handling could be compromised, but fortunately this is not the case. The DL2 only has a bare minimum of external controls and they are well spaced out so they’re not crowded. The handgrip is small compared to other DSLRs, but is comfortable to hold even for my very large hands. The sculpted shape is a definite improvement over the rather cramped grip of the *ist D, and a large thumb grip at the back makes for a very secure hold.
The viewfinder is large and bright, but is a bit lacking in information. Aperture, shutter speed, frames remaining, program mode, and a manual focus warning are all you get. The camera beeps for focus confirmation, but there are no focus points marked on the viewfinder.
Other options are more basic. The top slot on the menu is image tone, which has only two settings. Unfortunately, these aren’t labelled on the menu, but page 110 of the manual reveals that they are bright and natural modes. Other choices on the menu include three image sizes (1.5, 4 and 6MP) and four image quality settings including RAW mode. There are also sliders for saturation, sharpness and contrast, although the actual degree of control is limited.
The built-in pop-up flash is particularly nice. It has a stated guide number of 15.6, but I found that it was easily capable of lighting up a large room. It also doubles as a long-range AF lamp, firing as a high-frequency strobe so fast that it appears to be continuous illumination.
The DL2 uses the same 6MP sensor as the rest of Pentax’s current DSLR range, which is, I think, the same sensor as the Nikon D50. However, Pentax seems to have been able to do more with it than Nikon could. If you refer to my review of the D50 from December last year, you’ll find that it suffered from purple fringes on high-contrast edges and the white balance system tended to put a blue colour cast over everything.
The 18-55mm (28-70mm equiv.) standard zoom lens supplied as part of the kit is very good, especially compared to the sub-standard optics bundled with the Nikon D50. It focuses quickly and accurately, and provides excellent corner-to-corner sharpness and a minimum distortion. It did catch a little lens flare when shooting into the sun, but it is supplied with a lens hood to combat this. Pentax lenses have always enjoyed a very good reputation for outstanding quality with compact size and low weight, and thanks to the K-bayonet lens mount the *ist DL2 is fully compatible with every Pentax lens ever made, including old M42 screw-mount lenses and 645 medium-format lenses via adapters.



There is a function button on the back for quick access to white balance, ISO, drive/timer mode and flash mode, separate buttons for exposure compensation (handily located next to the shutter button) and AE lock and the usual playback, file info, delete and menu buttons down the left of the monitor, just as they have been on all previous Pentax DSLRs. The shooting menu itself is only two pages, but it has options to alter the saturation, contrast and sharpness, metering and AF modes and flash compensation. In other words it covers all the essentials without being over-complicated.
On the subject of memory cards, like the *ist DL and DS, the K100D uses SD cards for storage, and in highest quality JPEG mode a 1GB card is enough space for approximately 340 shots, while in RAW mode it’s 93. Like most DSLRs the K100D can shoot in RAW mode, as well as the usual JPEG, but unlike some models it can’t shoot RAW + JPEG, which will put some enthusiast users off.



The W20 is, at heart, a simple compact snapshot camera, and it has a range of options to match. Its standard mode is Pentax’s useful Auto Picture mode, whereby the camera will attempt to select the best shooting mode automatically. Pressing the Mode option on the D-pad reveals a selection of 25 shooting options and scene modes, including the usual selection of program auto, landscape, portrait, sports, surf & snow, fireworks and flowers, as well as some Pentax favourites including Synchro Sound Recording (recording the ambient sound for a few seconds when a shot is taken) and the ever-amusing Frame Composite mode, which allows you to add one of three hilariously awful frames to your pictures.
