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 What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras?
@khedron, autofocus occurs with the lens wide open. If the maximum aperture is within the limits given in the answer, AF will work with the capabilities and limitations given above. The maximum aperture is indicated on the lens. For example, you may see "1:3.5-5.6" for f/3.5-5.6, so the maximum aperture varies with the zoom setting. The lens is stopped down only when you take a picture.

comment How to shop for a lens filter?
The OP may be right, but only to an extent. I've found that a B+W F-Pro MRC filter clearly outperformed a Hoya Pro1 Digital filter. The Hoya filter had a subpar coating and was much more difficult to clean than the B+W filter. I haven't tried the Hoya HD filters, and they may be much better, but I'd prefer to stick with the one German brand I can trust.

comment How do cheap macro ring flashes perform?
The Metz mecablitz 15 MS-1 is less expensive at about US$400 (under $350 from B&H) and will function with any camera (or attached flash unit) from any of the major systems with wireless flash control.

@StanRogers, are you implying that (focal length != field of view) when the lens is not focused at infinity?

No. This is the other way around.

comment What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras?
This is all in the manuals, but it would be more convenient if there was a comprehensive list that can easily be found. I decided to "seed" this question and answer to help Canon users with regard to what their lenses allow in terms of autofocus.
