I own the 85/1.8 which I've used on a 30D, 40D and my new 7D. This lens is definitely worth the relatively small amount of money it costs. Autofocus is quite fast, and manual focus is much smoother...

There is no single, simple answer to that question but I'll try to give my best two cents.


If you're using Canon's Evaluative Metering, the camera is telling you (to it's best ability) that the...

Alright, you guys seem to be a wealth of knowledge on this topic, so at the risk of going off on a tangent, I have a question.


If I shoot 10MP Medium RAW images with my EOS 7D, is the camera...

I have owned both the Canon EF 20mm f/2.8 USM and the Sigma 20mm f/1.8 EX HSM lenses.


The Canon lens was fairly sharp stopped down, and focused quickly, but it was quite soft, and showed heavy...

Jayson, I own this lens. It is quite sharp (my copy produces results very similar to Bryan's), and focuses pretty quickly. Focus accuracy is dead-on. My personal, anecdotal experience says the lens...

I own the 17-55 IS, and use it primarly for weddings on my 40D. It is, hands down, the sharpest lens I have ever used on a Canon Digital Body. 35mm equivalent of 27-88mm is a pretty nice range, and...

You're right. To some degree there isn't much need for a mechanical shutter any longer. In fact, some (or maybe a lot, I'm not sure) lower end point and shoot digital cameras don't have a physical...

So I've been lusting over one of these new Eye-Fi SD cards, and was bummed to find out that they are currently not available in Compact Flash format. Then I found some cheap (~$20) adapters, in which...

I can't help but be completely confused by this thread, and by the general frequency with which people on this forum multiply the maximum aperture of a lens by a 1.6x crop factor when it's used on a...

This lens was purchased used on Ebay, about six months ago. The lens is cosmetically beautiful, with only one tiny (<1mm) nick on the lens barrel. The glass is flawless, not a scratch, mark, or spot...

I would sell the Tamron and buy the Canon 17-55 f/2.8 IS. I've used this lens quite a bit for wedding photography, and it focuses very quickly. I can't compare it directly to the Tamron, but I...

I've been in a similar position. The secret is to be underneath the rain cover yourself. I would start with a large trash bag, a rubber band, and a lens hood if you have one. Cut a small hole in the...

My experience shooting weddings has convinced me that if I was to rent or buy a lens specifically for low-light work, it would be a really fast prime, like the 50/1.4 or 85/1.8. The f/1.2~1.4 L...
