Your feedback counts!

Inspired by Thaddeus at Science Fiction & Fantasy Stack Exchange, I'm developing a new post style to make my answers better and more readable. I expect this style to evolve over the coming weeks and months as I continue to work on improving it. If you have any feedback or suggestions about this new style, come talk with me in chat and I'll listen.


I'm a computer and tech enthusiast with a variety of interests, from video games to fountain pens.

I take the accuracy and correctness of my contributions very seriously. If you find any problems with my posts, feel free to edit them or let me know in chat if you have any questions or comments.

I also enjoy taking pictures—I use a Pentax K-5 and a small selection of Pentax lenses. You can also find me on Pentax Forums.

comment Are equipment reviews from websites like kenrockwell.com and bythom.com reliable?
Also, I sense arrogance and hubris in his writing: when he mentions spherochromatism in his lens reviews (example), he refers to the general readership as "laymen" who confuse it with lateral chromatic aberration. Sure, this aberration isn't well recognized by people other than optical scientists, but it doesn't give him a license to effectively claim that he is no mere "layman".

@EvanKrall: With regard to the copyright warning, as I had conducted substantial research into IP law for a class project, I am keenly familiar with the four-factor test for fair use in the US. I am not a lawyer (so please don't take this as legal advice), but I have no reason to believe that printing a few of his articles would not be within the limits of fair use. He probably does understand copyright, but it looks like he's misrepresenting copyright law to dupe people into paying for a license that is simply not required.

Good point. Never thought of the the leg locks as a potential issue.

comment Why don't professional SLR cameras use SD or SDHC memory?
@MichaelClark: That's a CFast card. CFast is intended as a successor to CF and uses the SATA interface used by modern hard drives instead of PATA.

comment How do I troubleshoot the “Error, press shutter release button again” message on my Nikon D3000?
You meant: "Error. Press shutter release button again." This is a fairly common issue with many Nikon DSLR cameras, and it usually indicates a mechanical problem with the shutter or mirror unit. It is most prevalent with the D40, D40x, and D60, but can occur with newer models as well.

comment What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras?
@ides: Yes. This condition typically only arises when an extender is used. Note that the relevant aperture value is the maximum aperture. Even if your lens stops down to f/11, f/16, etc., what matters is the smallest f/number (largest aperture) the lens supports.

comment What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras?
@ides: Terms that compare the size of apertures, such as "at least" and "below", refers to the actual size of the aperture. Smaller f/numbers are consider to be greater than larger f/numbers, since they represent physically larger apertures. For example, f/4 is greater than f/5.6, and f/2.8 is below f/2. As such, f/4, f/2.8, etc. are considered to be within the range defined by "at least f/5.6".

comment What makes “fine art” fine art?
This definitely addresses the question in the most accurate manner. I, for one thing, consider a photograph "fine art" if it expresses some significant artistic intent.

comment autofocus and maximum aperture of 60D
See my answer to the linked question: "The limitations ... generally do not apply to third-party zoom lenses that have maximum apertures of f/6.3 at the long end of the zoom range, as they actually report a maximum aperture of f/5.6 to the camera...."

comment Pentax P-TTL: Why and when does underexposure occur and what can I do?
I don't have a chance to do this right now, but I do have several bad shots due to incorrect flash output. They'll have to be uploaded to my Flickr account, as Imgur does not keep Exif data.
