Olympus has a 300/2.8 design they could just take out and dust off, and Sigma makes all kinds of nice glass.

Nikon, as a mature company selling a mature product (DSLR's and lenses), doesn't really need massive R&D spending. They certainly still do it, though... *looks at 300 f/4 lens that's less than six...

Yeah... that doesn't really make sense. They could have had a much more cooperative venture, starting with an agreement about whether IS should live in the camera or the lens.

It's really a shame that the Olympus/Panasonic alliance in m4/3 hasn't resulted in more marketshare. Their technology is excellent on both sides -- the Panaleica lenses are great, the Zuiko lenses...

I definitely had the issue on a rented 300/4 two years ago on my D7100, so it wasn't just the D800. While you can certainly get "onion" bokeh out of it under certain circumstances, I find the bokeh ...

Reviews of good equipment are pretty short, since there are no interesting aberrations or flaws to talk about. The 300/4 is such a lens: images are sharp wide open with no visible chromatic ...

I have the Toshiba-sensored D7100 and, other than banding in some extreme circumstances, it's a fine sensor.

re: high ISO noise: remember that you in general get faster apertures than the DX crowd. You have f/1.2 or f/1.4 available for a lot of focal lengths, and the very high sharpness of a lot of the...

Olympus has always made fantastic stuff, dating back to my old E-510. They were held back by bad sensors for a while (made by someone else), but now that they've got access to good sensors, anytime...

When it comes to doing "real photography", this stuff matters only on the margins, but those margins do exist, and sometimes it's important to know what happens there.

For much of the stuff I do,...

The amount of light isn't that important until you get into shutter speeds that are long enough to probe dark current (like 1 second); the most notable thing about the incandescent light is the...

I shot 4/3 for years but never got a chance to use the 50 f/2; I used the 35/3.5 with teleconverters for macro work (which was quite a good lens, really)

Nikon ought to offer their cameras with...
