Dear HDR users
I am considering to buy a camera + fisheye in order to make luminance measurements (mostly daylight scenes) and calculation of glare indexes.
The camera seller said me that the only solution to have a full 180° view is the combination of the sigma f3.5 fisheye + a full format numeric camera (called 24/36 like with analogic cameras) and the cheapest one is the CANON EOS 5D (around 2500 euros).
I know that some of did some daylight measurement with cheapest camera. Who can help me with that topic ?
Thanks a lot
Magali

Hi Magali!
The SIGMA 8mm fisheye will work on a more reasonably priced camera with a
cropped sensor (usually about factor 1.6 or 1.3), but you won't capture the
full circle of 180deg.
However, I read a while ago that SIGMA is planning to release a full 180deg
fisheye for cropped sensors (like those used in the entry and semi-pro SLR
lines).
Here are the links:
http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3336&navigator=6
http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3337&navigator=6
These can then be combined with the more affordable Canon or Nikon SLR
bodies.
A benefit of a 36x24 sensor (full frame) might be the better low light
sensitivity due to larger photosites (pixels). It might be therefore worth
to give the camera systems of choice a try if possible if they fit your
need.
Cheers,
Timo

If a 3 MP camera will do, and you're not afraid of using a system that
isn't exactly cutting-edge, then you may use a Nikon CoolPix 990 or
995, in combination with a Nikon FC-E8 fisheye lens.
You'll get the cam + lens for around £/$/€ 200 on e-bay. I've used
both systems in the past, and would happily point out the pros/cons of
CP990 vs CP995. They actually differ quite a bit. Let me know if you
would consider this option.

Hi Magali,
I agree with Axel's comment. There are also some new(er) cameras that can use the FC-E8 or FC-E9(an improved version) Check http://nikonimaging.com/global/products/accessory/converter/list.htm I've used the Coolpix 5000, and they work very well in my experience.
However, be aware that with the latest model (Nikon Coolpix P5100) which I believe can take the fish-eye with an adaptor, you cannot use bracketing in manual mode which can be problematic, but that depends on the application.
Good luck with your measurements, and please keep us posted.
Regards,
Santiago
