The 11-18 lens gives me a noticeable hotspot, Sigma 50/1.4 does do the job though.

Cheers

Minolta 28-85 F3.5-4.5. No hot spots what so ever. My IR lense for now. Images below were taken with converted A100 and Minolta 28-85.

I want to try out the Sony 18-250 for hotspots. That would be the perfect lense for my A100 :D

*edit can't seem to get my image to show up so edited for links

Just tested two more of my lenses.

Please add to the GOOD department. I tested at different focal lengths and did not see any hotspots.

Tamron 70-200 F2.8
Tamron 200-500.

Thanks and just happy to contribute to a WELL Needed posting for any one doing IR with the Alpha's/Maxxum's.

Would you say the 50mm is good or decent?

Just to add my two cents on the Sony 50 1.4, it produces very noticeable hotspots on my A700. I have several examples and immediately dumped it from my IR lineup and got the awesome minolta 35-70 just for IR.

I might be a bit off topic here, but did anyone test the a550 with IR?

I used to do lots of IR on my a200 and it was great, but when I went to test some on the a550, results seemed a bit weird (underexposed mostly)
I'm waiting for sunny days to test some more.

Could be the same issue I had with my A900. The A100 worked great unmodified, as did the A700, but the A900 was useless for unmodified IR. The newer filters were just too strong!

Camera list time? I can add it to the first post if people would like.

My list so far for unmodified cameras: UPDATED 11/08/2010

Good: (typical unmodified shot times)
Sony A100
Sony A700
Sony A200 (thanks to C-Hass)

Decent:

Bad:
Sony A900 - IR filter is too strong for any usable results

Hey Groovy

yeah do add the camera lists. I think it'll be useful for anyone wanting to do IR work.

I know Minolta's 5D and 7D work too (unmodified). I've read another post on dynaxdigital.com that people use 5D's and 7D's.

I had a A300 and it worked great for IR work as well then I sold it and got the A700.

Hey Groovy,

here's from dynaxdigital.com forums and a member posting with the 5D and 7D


All you need to do now is buy yourself an IR filter.

"From experience we as Minolta/Sony owners are lucky as our DSLR’s are suitable for taking IR photographs.
I have used the
5D
7D
A700
And successfully taken IR photographs with them, although I have not used the following camera's, I have been informed by other members that these are also suitable for IR.

A300"

Most likely due to the changed title, but it's sticky again
