  • What's the point of these comparisons if you do not control the light level or angle or exposures for the different cameras ?

    For example:
    RAW, ISO 204 800, Incandescent

    A7S: 1/640, f5.6,...

  • Yes poorly designed. If the lens is subject to high variation in performance then it is not very robust against expected manufacturing variation or operating conditions. Good engineering ...
  • This is all irrelevant. Packaging and transport methods are pretty standard across the different lens manufacturers. The fact is the 20-40mm is a lens with undemanding optical specifications that ...
  • Replied in OMG!!!
    This is not correct. The DC motor in Pentax lenses like the 18-135mm is a simple direct current cored micro-motor that you can find in many consumer goods. The motor is coupled with a simple ...
  • Good summary. I saw that patent a while ago and thought that they would have addressed the issues but it seems they still remain based on the many ongoing reports of SDM failures with relatively ...
  • Commented on Hands on with the Pentax 645Z article

    The difference between this sensor and the largest digital MF sensor is ~0.5 stop. Seems a good compromise for a substantial price saving.

  • Commented on Hands on with the Pentax 645Z article

    All the whiners who can not deal with the fact that this camera has a sensor with only a 55mm diagonal should really think about how much a larger sensor camera would cost if this one is already...

  • What are the strengths of Phase One and Hasselblad offerings compared to this? Just curious

  • $30 000 - $8,499.95 = Pretty much buys you all the lenses you want and a spare body for "professional services".

  • Pretty impressive. It is much better specified on all accounts than its rivals and costs less than 1/3 the price. Why would anyone buy a $30k Hasselblad or PhaseOne?

  • It will  probably have 1920x1080 @ 60i (if that) and 4K timelapse movie made from stills, just like the K3. Considering Pentax puts very little effort into video the chance of 4K video is pretty ...
  • Yes. From the current DSLR makers only Canon and Sigma (which basically uses the Canon protocol) use control aperture with in lens motors. They already have to do a mechanical linkage design for ...
  • Their answer regarding the fact that Pentax still uses mechanical aperture is not really convincing - Nikon and Sony both still use mechanical aperture linkages too, with the Sony implementation ...
  • Commented on Pentax K-3 preview

    You seemingly rank viewfinder quality based on size alone. It would be beneficial if you mentioned other characteristics like:

    - Eye-point
    - Colour balance
    - Manual focusing ability
    - Legibility...

  • This is not incorrect. Have you tested it yourself? I have the camera here and have tested it extensively. It is definitely software based SR and it definitely produces software SR induced skewing ...
