  • 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...

  • I rented one last summer to use for wildlife/nature use with my D7100. I didn't shoot it stopped down much because it's very sharp at f/4, even with the 1.4x teleconverter. But when I did (usually ...
  • As someone who actually shoots these sorts of lenses, the Olympus 300 and the Nikkor 300 are going to be used for much the same sort of work. The pixel density is similar between 24MP DX (what I...

  • @Sabatia: Was this the old 400 DO, or the new one?

    I've used the Nikon 300/4 Fresnel under very demanding conditions: on the D7100 (pixel dense sensor), wide open, and with a 1.4x teleconverter....

  • That's clearly moire, caused by the fine structure of the feathers.

  • The argument makes no sense -- we're spoiled for choice. Both 300 f/4's are great lenses; I've shot the Nikon one, and I have no doubt the Olympus one is fantastic, since most Olympus lenses are...
