Infra red filter - question

[gferdinandsen]

Another option to having an older DSLR converted by Lifepixel. Is to check eBay for Lifepixel converted P&S. Before I had D40 converted to 590nm, I bought a G9 conveted to the same cut-off for about $300 off ebay. Once I was happy with the choice of wavelength cut-off, I just relisted the P&S back on EBay.

just came across another resource at lens rentals.com:

http://www.lensrentals.com/rent/canon/cameras/infrared/canon-5d-mark-ii-ir-modified-715nm has a list of recommended lenses

I had my 40D converted by LifePixel - they are great! One thing I ran up against pretty quickly, tho, is that a lot of lenses, in particular the 16-35 I was hoping to use for landscapes, have a nasty PITA "hot spot" of reduced exposure in the center of every shot [due to the way IR reflects inside the optics]. I'm currently looking at the Sigma 15mm to use on WA shots, since it is reportedly better. It would pay to research your current lenses before you commit to IR.

The 16-35mm is indeed not recommended for IR work. Here's a link on which lenses are suitable or not for IR photography: http://www.lensplay.com/lenses/lens_infra_red_IR.html

Cheers.

It seems to be a rather "old" list.
In the list the Canon 16-35mm is mentioned but not the MKII. Does it mean that the MKII does not have the hotspot problem?
I also do not see the Canon 24-105.
Are there any updated resources of what lens to use and what not?

the mk2 does have the problem as i've tried it its not good

These lenses do not have hotspot's in my experiences.

24L
50L
135L
24-105L

the 50 f1.4 is just as bad as the 16-35 mk2 aswell

Here's one updated link from Life Pixel I stumbled today that proves that the 16-35mm II has hot spots, indeed. This also includes the superb 24-70mm II. http://www.lifepixel.com/lens-considerations

Thanks. Wow, even the 24-70 MKII.
What about the Tamron 24-70 VC ? I googled but could not find info yet.
