Compact Size with a magnesium alloy shell of stainless steel chassis.
Selection of lenses designed for the APS-C imaging sensor
Shake reduction with every lens
Ergonomics
External Mic in video mode
Very quiet shutter
Industry first Composition Adjustment and horizon level (separate features)
Cons:
Battery life in Live View/Video mode.
Not a beginners camera unless you have a strong desire to learn about photography
High ISO performance could be a bit better
What previous Pentax users will notice:
Refinement, refinement, refinement
Low light autofocus is fast and accurate (inline with the competition now)
AF-Continuous is fast, but not class leading.
Ergonomics different from previous K10d and K20d (maybe good, maybe bad depending on your position)
Insignificant change in image quality from K20d
Can disable long shutter noise reduction for shots 30 seconds or less
Excellent sensor dust removal
Who should buy the K-7? Anyone looking for a prosumer dSLR (Nikon d300, d300s, Canon 50d, etc) that they want to take anywhere. This thing is for serious adventurers, with its full weather sealing and wide array of weather sealed lenses (DA* or WR series lenses). Going on a trip to Alaska? Hiking in the back country? Canoeing down the Colorado? Or even if you just want a smaller dSLR with all the features of the big boys from Canon or Nikon. This camera steps up the competition.
What new to Pentax users should be aware of? The camera makes slight noises when you pick it up or turn it on. The sensor is free to shift in its mount due to the shake reduction system. This is totally normal, but scares some first time users where they think something might be broken.
Detailed review:
I have tested out the weather seals in a driving rain, where I shot video using my DA* 60-250mm lens. The seals held up well and the camera still works, so all is good. Having used previous Pentax cameras, I have had minimal trouble with batteries dying in the cold like some friends with Nikon's and Canon's have. I had my K20d out in -30 F weather for 1.5 hours once. The camera had frosted over.
The camera is diminutive, but feels like a little tank. It is sturdily built and feels great in the hand despite the compact size. Without the grip I only have 3 fingers on the grip, but this is the same way I held my much larger Canon 5d when I had it. The K-7 is comfortable for me to hold for long periods, I support the camera with my pinky finger.
Pentax has a stellar selection of lenses for APS-C cameras with a wide array of fixed focal length lenses (primes) for best image quality, or large aperture zooms (f/2.8), medium aperture zooms (f/4), or "consumer" zooms (f/3.5-5.6). To find a list of Pentax lenses, visit Pentax Imaging USA's Website. If you want weather sealed remember to buy WR or DA* lenses, non of the others are weather sealed.
It is important to note that shake reduction works with every lens for the Pentax system, usually around 2 or 3 f-stops, but up to 4 for those with shaky hands. This is invaluable to have a 50mm f/1.4 with shake reduction for those available light shots, just remember that shake reduction allows a slower shutter speed so it isn't ideal for moving subjects. Also remember to wait a split second for the shake reduction icon to show in the viewfinder before taking your picture at slow shutter speeds.
The ergonomics are intuitive for the K-7, but might throw some previous K20d users for a loop. Users coming from the K-2000 (K-m in foreign markets) should be able to adapt quickly, as it is very similar. One of the new design paradigms is quick access to everything through the info menu on the back. Also use the info button to disable the LCD (for those that do night shooting and get blinded by it). There is a direct ISO button now too, for those that didn't know it was hidden under the OK button before. Typical of modern electronics there are several over-loaded button functions, so it pays to sit down with the manual and read over it, but overall it is intuitive. The screen often shows you what button to press (like a little symbol of the front e-dial is shown to change a particular setting using that dial). Similar to the K20d, but slightly different too. Be sure to download the latest firmware from Pentax for better use of the AF Select mode (for selecting your own autofocus point).
The video mode is reasonably good. It uses motion JPG compression (AVI) which results in huge file sizes, but minimal artifacts while panning or during motions scenes. It records 720p at a fast 30 frames per second, most of the competition only does 24 fps. Max is 4 GB per file, which might be 8 minutes or so at max quality, or 30 minutes at a lower quality. Like all dSLR video cameras the internal mic picks up every sound the camera makes, so ideally you should use an external mic for high quality video. Only two dSLR cameras allow that at the time of this review writing, and those are the Canon 5d which is twice as expensive as the K-7, and the K-7. The soon to be released D300s will allow an external mic too, but it has a targeted price of $500 more than the K-7. This makes the K-7 one of the best bargains in dSLR video.
The refinement of this camera is stellar. The shutter is very quiet for a dSLR (if you are coming from a point and shoot it is of course much louder), but it is unobtrusive and professional sounding. No more clackety clackty whirrrrr that the older K20d made, one of those noises that turned every head in the room. It is also nice the shutter acts separately from the mirror, so mirror blackout times are minimal and the shutter can be fired multiple times without cycling the mirror, like in live view.
This camera also has an extreme degree of flexibility in configuring JPG options, you can customize several different JPG modes ranging from vibrant, muted, natural, portrait, etc. You can change the key, contrast, saturation, sharpness and more. You can also take 3 shot HDR images right in the camera with decent results. Finally, you can do a wide degree of image processing right in the camera using built in digital filters and also RAW developing.
The composition adjustment can be used to make small shifts left and right and rotationally using live view mode. These are very handy for fine tuning the composition and are equivalent to shifting on a tilt shift lens (just to a lesser degree, 1mm each direction). The level is also handy, allowing you to easily see when the camera is not perfectly straight, or it can be set to automatically level the horizon.
So, I have had a pretty glowing review so far, what are the downsides?
I have shot 2000 shots through the K-7 now, and it has performed as expected. I have charged the battery maybe 3 times, so life is reasonably good, except when using live view or video mode frequently. The camera sometimes thinks the battery is going dead when it is low and turns the camera off. You can still shoot pictures if you turn it back on, but not much video or live view. However, you can still get a lot of use from the video or live view before this becomes an issue, and if it does you might invest in a battery grip or AC adapter.
My only disappointment with the camera is I wish ISO 1600 performed half a stop better. The noise is relatively pleasing though, and will lead to good prints or black and white conversions.
This camera has an intimidating array of buttons and options. If you are a beginner, and have no intent to learn photography in terms of exposure and aperture, I would hesitate buying this camera. Pentax's entry K-2000 might be worth a look in that case.
However, this camera really brings everything to the table and if you are an advanced consumer or even a professional looking for a feature rich camera, this Pentax is definitely worth a look. This camera is an amazing price considering the competition.
