Which lenses have you found work well for Infrared on modified or unmodified cameras? Which cameras have you found to work well unmodified?

My list so far: UPDATED 7/16/2013

Good:
24-70Z - great color with custom IR, but occasional hotspots
Minolta 24mm f/2.8RS - No hotspots, beautiful results - PERSONAL FAV
Minolta 28mm f/2 - No hotspots, different WB than Zeiss but good results
135Z - Weird color shifts, but no hotspots yet. Color easily edited with CWB.
Sony 16-105 - So far so good. Maybe very mild hotspots, maybe.
Sony 18-55 SAM - No hotspotting, looks good (Thanks sdm9465)
Sony 35G - Excellent for IR. Great color, no hotspots.
Minolta 35-70 (thanks Twah)

Tamron 200-500 (thanks Twah)
Minolta 28-85 F3.5-4.5 (thanks Edinator)

*NEW*Minolta 28-85mm f/3.5-4.5 - good, but colours not as punchy as the sigma (Thanks mrggt)
*NEW*Tamron 20-40 F/2.7-3.5 - Central soft hotspot, pretty easily correctable. (Thanks kerrath)
*NEW*Sigma 24mm F/2.8 - Good image quality, even when close-focusing. No hotspots. (Thanks kerrath)

I tested the 16-80Z some more and had no hotspots, so I am confused. I also tried the Sony 50 f/1.4 and it had no hoptspots but a big blue shift.

um, perhaps it's a dumb suggestion, but did you put the VF blind on while exposing.

Lights could gou into from the VF into the sensor on long exposures, hence the shift you see.

If you already did that, then don't mind my comment.

he has an IR-modded A100, so i don't think long exposure is necessary

Like Soulfly said, these trial runs have been on a modified camera. When I shot the long exposures on my A700 I did use the VF cover.

The camera I had been playing around with for infrared photography (a Minolta DiMage 7) died recently when a water bottle in my backpack opened and flooded it. I'm now thinking of getting an A2xx/A3xx converted to IR and am wondering how the new 18-55mm kit lens would perform. Any one have any experience with that for infrared? I don't have any other lenses that are an ideal range on APS-C and would rather not have to share lenses with my A900.

I continue to try many lenses on my modified 7D/IR. Because I had mine calibrated for a 24/2.8, I've has BF issues on a number of lenses. I can have it re-calibrated to another lens by Precision and thinking it will be either the 16-105 Sony or 28-135 Minolta.

Having said all that, these are my favorites, even with the BF issues.

24-70Z, like groovyone, there are occasional hot spots but overall great lens for IR.
28-135, some softness at the tele end, 28-approx 80mm is wonderful.
58/1.2 Rokkor-X: most fun lens, gives a real feel of of Kodak HIE, still using the M to A converter, haven't decided if the slight softness added by this converter helps or detracts from the look.
24/2.8, original lens sent for calibration, still gives the best results at all apetures and I prefer the 36mm
slightly wider view as all purpose.
16-105 Sony, Best available range, but will need to be calibrated to serve as all purpose lens.
Lensbaby composer: My newest toy! I'm learning how to focus (tripod mounted, multiple shots) but once I feel confident, it will be a regular part of the kit.
100/2, lots of hot spots, BF like crazy at infinity but worth the work to get it right.

Still others to try...

Sigma 10-20 good, tested on KM 5D and Sony a700
Kitlens 18-70 very good, tested on Sony a700
Tamron 17-50/2,8 - very strong hot spot, definetely not recomended

All tested on unmodified cameras

Good to know on th e17-50 Tamron, since that was going to be my next attempt.

Round 2 of the 16-80 went better, but still not convincing. I just got a 24mm f/2.8 RS to try, so I am glad to see 2many's statements. I also have a 28 f/2 to test out on it.

Haven't done this in a while (the A100 was OK for it, the A700 has a too-strong highpass filter in it), but:

- 17-35/2.8-4 has a strong central hotspot
- 10-20 works well
C&C always welcome

I got an A200 modified and have so far only tried two lenses:

135/1.8: I had the same experience as groovyone.
18-55 SAM: Works great with no hot spots. (I bought this lens specifically to live on the A200 so I'm glad there are no issues.)

Of my remaining lenses, I doubt I'll ever use most of them for IR. I'll probably try out the Minolta 24-105 and 100-300 APO as that would cover quite a range in a light and compact kit. I'll post results if and when I test them.

Forgot all about this thread.

I can add to it.

Good:
Sony 16-105 - looks surprisingly good so far
Minolta 24/2.8 RS - still looks great!

16-105 @ f/3.5, ISO 200


24mm @ f/5, ISO 200



24mm @ f/6.3, ISO 200
