comment Why do the cameras Canon 1Dx, Nikon D4, Nikon D5 have a different form factor than other DSLRs?
@MichaelClark: +1. My Pentax K-5, and to a lesser degree, K-3 II, will slow down noticeably as the battery is discharged. Having maximum power available is a huge deal when you need maximum speed.

comment What caused the sky to turn green in this photo?
@Logan: You might want to post the original image on Flickr and provide a link to it as Imgur does not preserve Exif data.

comment What caused the sky to turn green in this photo?
Seems to be a white balance issue to me. The saved image should contain Exif metadata which specifies the settings the camera used. The D70s is also a very, very old camera (dating back to April 2005, more than a decade ago) and I strongly recommend that you consider upgrading to a newer model as sensor and image processing technology has changed dramatically since.

comment Are lenses for Nikon's D5xxx series compatible with the D7xxx series too?
Yes, they are, but not necessarily the other way around. AF-S and AF-I NIKKOR lenses are fully compatible with the cheapest Nikon DSLRs, but AF NIKKOR lenses will not autofocus on a D5x00 or D3x00 camera (although these are mostly older lenses).

comment Why don't compact digital cameras have the aperture range of DSLRs?
Diffraction is the key issue here. While my Nikon COOLPIX S9900 has full aperture control down to 1/6 of a stop, stopping down past about f/5.6 or so visibly degrades sharpness. The effect is especially noticeable towards the wide end of the lens where faster aperture stops are available (the difference in sharpness between f/5.6 and f/8 is dramatic especially at close focusing distances). Stopping down past f/8 (which the camera doesn't allow, as mentioned by your question) would only make things worse.

(continued) These constraints are much less pronounced with large DSLR-style bridge cameras, but you can only go so far before a DSLR or mirrorless system camera becomes a more viable solution. The Panasonic Lumix FZ300 manages to do a constant f/2.8 throughout a 24x zoom range but it's also very expensive and nearly as large as a entry-level DSLR with kit lens.

Also, the real reason for the low diffraction limit is the size of the pixels, not the physical focal length of the lens. The Airy disk will always be a certain size depending on the aperture of the lens, and smaller pixels due to the smaller sensor only exaggerates the issue. A faster, better-designed lens will be better at this, but you quickly run into size (and cost) constraints when you try to make a fast lens with 10x or more zoom and isn't much larger than the S9900. After all, the physical aperture size is limited by the size of the front element.

Not all compacts lack proper aperture control. My Nikon COOLPIX S9900 has a 6-blade diaphragm with aperture control down to 1/6 of a stop.

comment How does RAW prevent “ugly digital clipping”?
(continued) Heck, the advantages of RAW, including the ability to perform more effective noise reduction and other post-processing on a PC after the event, is significant enough that I shoot sports in RAW+JPEG, even though it dramatically reduces the buffer depth! (My employer often wants an immediately usable JPEG image for their website right after a game, and I turn in the rest of the images a few business days later.)

comment How does RAW prevent “ugly digital clipping”?
Shooting in RAW doesn't guarantee the elimination of highlight clipping. However, RAW files contain the full information captured by the image sensor, which generally includes highlight detail beyond what would be captured in a JPEG image. Keep in mind that RAW files typically have 12 or 14 bits of tonal data per pixel while JPEG is limited to 8 bits, so there's significantly more data to work with in a RAW file. I know this first-hand and have recovered from clipped highlights in JPEGs countless times when I pull up the RAW file in RawTherapee. See also: photo.stackexchange.com/a/13448

comment Why do Full Frame lenses and crop body lenses exhibit the same crop factor when used on a crop body camera?
The crop factor is a function of the sensor, not the lens. The sensor size determines the crop factor—Canon APS-C bodies have a crop factor of 1.6. The lens used on the camera body doesn't change that—the sensor is only a fraction of the size of a full-frame sensor, cropping out the part outside the bounds of the APS-C frame that would otherwise be captured by a full-frame sensor. That's why we call it "crop factor".

comment Does mirror lock-up drain the battery?
On Pentax K-system DSLRs, holding the shutter open requires power. However, holding the mirror up does not. If you pull the battery in Live View, the shutter snaps shut but the mirror stays up.

comment Why is my Canon 55-250 IS lens blurry at focal ranges beyond 100mm?
Voting to close as duplicate of Pentax DA L 55-300mm lens very soft--is it broken?. It's essentially the same issue affecting a very similar lens on a different camera system.

comment Shooting full manual during an event or function
Does your camera provide a manual mode with auto ISO? I know for a fact this can be done with Nikon cameras, and many Pentax cameras have a "TAv" mode.
