Originally posted by abruzzi I think the issue with full spectrum is it will let UV and IR through so you’ll get somewhat washed out images (from the examples I’ve seen.). My expectation is that post conversion the camera will be dedicated to the purpose you converted it (that why I didn’t convert a $2k camera.) I primarily wanted the HIE look, i.e. only IR light longer than 830nm, but if I had that filter installed inside the camera I couldn’t do the “aerochrome” color IR look (prior to this all my infrared photography was on film so I think in terms of the look of various IR films.). So I went with the 590nm filter which means, filterless I get the Aerochrome look, but I can easily stack a 830nm filter. It’s a little more cumbersome to shoot B&W IR but not bad. Right now I’m using a 40mm XS lens primarily (with a 27mm filter), but the camera bag has a 21 limited and a 70 limited which both take a 49mm filter. I’ve been very pleased with the results. I’ll see if I can post something later.
OK, so FS is out, good to know. Isaac says in
website that 590 is the most versatile and can stack filters, but honestly of all the wavelengths, I am not thrilled about the 830. I can see myself doing 720 most of the time but with an option for 590.
I have a 40XS and bought a Hoya 52mm IR that can go on various, including the 18-55 DAL which was supposedly surprisingly good for IR on an unconverted camera.
EDIT: Isaac just answered me!
I would be happy to convert your K-01 for you. One factor that might
play a role in your decision is that a 590nm conversion for the K-01
would cost $175, while a full spectrum conversion would cost $150.
Obviously you can use any IR filter on the lens of a full spectrum
camera, but you can also use IR filters on the lens of a IR-converted
camera as long as they are higher than the internal IR filter. So yes,
if you put a 720nm filter on the lens of a full spectrum or 590nm
camera, the camera will perform exactly the same as if it was converted
to 720nm.
I hope that helps. Let me know what you think or if you have any other
questions.
Thanks,
Isaac
