Because people shoot different things, and need different focal ranges. There's no magic about an 18-50mm. 18-50mm is more useful for landscapes, but isn't a good option for portraits. On crop...

Panasonic GH2/GH3 are the only really worthwhile choices on the market.  For skateboarding, the Sony dSLTs would be better, due to the focus system, but the audio quality is poor, and the video...

My experience is not current, but I bought an underwater point-and-shoot many years back. The image quality made it not very useful for anything other than underwater use (Olympus...

As folks mentioned, most lenses will vignette a little bit. How much depends on the specific lens. Tamron doesn't make spectacular lenses, so I'm not surprised if it vignettes a bit more than most...

Slightly incorrect adapter length would do that -- more likely too short than too long.  Most lenses do not have a hard stop at infinity; turning it all the way will focus a little beyond infinity....

In terms of what's important in photography, this is a list, roughly ordered by importance:  Being there (good choice of subject, being there at the right time, etc.) Good lighting Good...

Good comparison, although "roughly equivalent" is a bit of a stretch. The NEX is roughly a stop ahead in equivalent aperture, which sets DOF. The Nikon 1 is a niche product for places where you...

Good comparison, although "roughly equivalent" is a bit of a stretch. The NEX is roughly half a stop ahead in equivalent aperture, which sets DOF. The Nikon 1 is a niche product for places where...

If you can afford it, you're looking at a Panasonic GH3. If you can't, you're looking at an older Panasonic GH2 (preferably used, for a nice discount). Many professional videographers use it...

In my opinion, by far the nicest compact camera (excluding esoteric super-premium models like the RX1, Leicas, etc.). It's expensive, but it's a radical step forward in what you get out of a...

I thought that too. Gerry corrected me. I looked at data. I was wrong. Longer lenses are generally better optically (distortion, bokeh, etc.), but not for sharpness. The sharpest lenses for the...

$2500-$3000 on a 5D MKII is not even in the ballpark of being enough. You'll do much better going much lower-end on body, and better lenses. I wouldn't switch to full-frame unless I had about $7000...

I was looking for data to back me up, and I found out that you are, indeed, correct. There are some very sharp wide-angle lenses out there, and there is less correlation with focal length than I...

I watched the video you mentioned on photos of children. Thank you. Direct link: http://www.youtube.com/watch?v=aTCQlFcDb9A It was helpful, but I would have done this shoot quite differently. If...

The sharpest lenses are all longer focal lengths (100mm, 200mm, and similar). There are very few really good wide angles. So no. On the other hand, there are differences in specific cases with...

This is a very clever way of looking at it. Unfortunately, it leads to incorrect conclusions. It would be closer to correct if lenses were perfect, but lenses have real-life manufacturing...

If you ever get into serious photography, the D7000 is a dramatically better camera than the D3200. The focus system, viewfinder, and ergonomics will be better than an entry-level camera. This...

A lithium ion battery can explode if you discharge it too quickly, overcharge it, charge it too quickly, overheat it, undercharge it, etc. Industrial-grade batteries are like hand grenades....

Summary: Last I checked, a few years back, full frame was very expensive. As you step down in size to APS-H, price falls dramatically. Below that, price drops much more slowly. Explanation: There...
