2011.05.22, Lake Deseda, near Kaposvár, Hungary

Nikon D90-IR - 16-85VR @ 16 mm - f/7.1 - 1/125 sec - ISO 400 - B+W 093 infrared filter (830nm) - NEF - Capture NX 2.2.6 - PS/CS2

Took my recently bought (2nd hand, yay!) 830nm external IR filter for a test drive on my IR-converted D90 (~695 nm).

Pretty heavy result, huh? ;)

The only problem I'm having so far is the camera shake (hence the iso 400 here) - it's amazing how hard it is to keep the shots still in live view, when you're holding the camera (without the grip) in front of you, mid-air. Any tips?

Nice shot, I really like this :)

To answer your question on reducing the iso from 400 for handheld shots...

Your 16-85VR has an aperture of F3.5-F5.6, if can you find a lens that has the same filter thread as your B+W 093 AND has an aperture of F1.4 or F2.8, it will let in more light, reducing the need for a higher ISO.

This image was taken with an aperture of F7.1 (which lets in less light to the sensor) so maybe also shooting in A mode will give you more control? (with possible loss of overall sharpness in larger apertures)

Thanks for the tip, but looking at my gallery, you might guess I know how to adjust iso, aperture and shutter speed. ;) I stick to f6.3-f8 because that's the sweet spot of sharpness in IR on the 12 MP APS-C sensor, above and below these settings things get really soft.
Faster lenses, that work in IR too? I don't know of any I could afford - the 17-55 Nikkor is bad in IR (!), all the 3rd party fast zooms (Sigma, Tokina, Tamron, etc) are crap in IR too. Older fast primes have hotspots, newer fast primes, or more recent fast zooms (14-24, 24-70, or 17-35) all cost an arm or a kidney. And I don't have any spare arms or kidneys... ;)
Actually, the trick is in the neck-strap as I've found out. When I hold the camera away from me, as far as the strap allows, so that it almost hurts in my neck, well, then the shot will be sharp most properly. :nod:

Ah the hold your breath and brace neck strap trick! Haha, I can never pull that off, but I not got a converted camera ;)

Try here for some good nikon lens' they have a bargain basement too :- [link]

Nice to know about the sweet spot on the 12mp APS-C Sensor (cmos) as I thinking about picking up a D7000 (also a cmos but 16.2mp) or a Canon 7D/60D and will keep that in mind. :)

Those aperture settings are for infrared photography. At 16-18MP APS-C/DX things get even worse: at f5.6 diffraction starts to kick in already, so with slow lenses you can find yourself get diffraction limited even wide open.
For visible light, check the different lens review sites for the optimal settings - photozone.de, slrgear.com, etc.
