I'm primarily a computer and photography enthusiast, but I have a variety of other interests as well, from video games to fountain pens. I take the accuracy and correctness of my contributions very seriously; if there are any problems with my posts, feel free to edit them or let me know in chat if you have any questions or comments.

As a photographer, I use a Pentax K-5 (as well as a K-r as a backup or secondary camera), with a small selection of Pentax lenses. You can also find me on Pentax Forums.

comment Why is dark-frame subtraction on my Pentax camera shorter than the exposure time?
I don't see why this should be downvoted. Temperature is indeed measured by the camera and used to determine noise reduction.

I never drew this conclusion from what the manual said... Thanks!

There is no cap on my K-r. I've had exposures several minutes long and the dark-frame subtraction time continued to increase with the exposure time, but it was never as long as the actual exposure.

comment What are some common gotchas and missed capabilities migrating from compacts to DSLRs
This question is somewhat subjective but useful, and an answer would be a list of possible problems that would benefit from collaborative editing, especially when there are answers that are intended to be added to one master answer. Flagging for moderator to make community wiki.

Suggest this as an edit to Matt Grum's answer.

comment Which lenses are best for macro and for birdwatching (both Canon and Nikon)?
With this kind of dynamic range, seeing is believing: photography-on-the.net/forum/showthread.php?t=955995

@MattiaGobbi: See this DxOMark comparison for an idea of what this image sensor can do: dxomark.com/index.php/Camera-Sensor/Compare/Compare-sensors/… Well, technology has advanced to the point where APS-C image sensors are clearly competitive with full-frame sensors...

comment Which lenses are best for macro and for birdwatching (both Canon and Nikon)?
@Itai, you're right. The Pentax K-5, Nikon D7000, Nikon D5100, Sony α580, and Sony α55 all share the same 16-megapixel Exmor APS HD CMOS image sensor with about 13.5-14 stops of dynamic range. Additionally, the Pentax K-r and K-x both use a 12-megapixel Exmor CMOS image sensor.

comment Is it risky or difficult to wet clean an image sensor?
I took a leap of faith and went ahead with wet cleaning. After three Sensor Swabs, some Eclipse, and my blower bulb, the sensor was essentially clean without any damage. Thanks for your help, @MattGrum and others!

comment Why does a bigger sensor lead to a shallower depth of field?
+1: That pretty much sums it up.

I'll buy the Photographic Solutions cleaning products. It seems that reports of sensor damage are caused by improper cleaning tools or procedures; failures resulting from proper use of the correct products are rare, so I'll take a shot at it.

@JohnCavan, the K-5 and K-7 have an ultrasonic vibrating low-pass filter for self-cleaning, unlike the K-r and other entry-level models.
