here comes a post, i normally comment in other Forums with "you pay peanuts, you get monkeys
but thatÂ´s what it is about.
Actually i am shooting my panoramas with 24mm Canon lense. It works great. BUT I want to become faster - and the high resolution is not needed for the webprojects the panos are used for.
so i thought about a fisheye, where i can handle a 360 with 6 shots.
Lense for canon fullframe bodies.
And here the challenge: Is there a cheap lense out there, that offers acceptable quality?
The best way is to look for a 2,8/15mm Canon fullframe-fisheye when you use a Canon FF or a Nikon 16mm fisheye when you are on Nikon. You can get the 15mm these days fo a very reasonable price because itÂ´s out of production. The actual Canon fisheye is a zoom: 4/8-15mm. It provides surprisingly good image quality - but makes only sense whe you really need both focal-lengths.
The Canon 2,8/15mm fe and the Nikon 2,8/16mm fe need 5+Z shot @20% overlap resp. 6+Z @25% overlap. TheyÂ´re very good and sharp lenses.
Using an 8mm fe on a fullframe camera in my eyes is pure nonsense - you give away lots of resolution . . which means image-quality.
I donÂ´t know which camera you use. IF you use a DX camera i strongly suggest the Nikon 10,5mm - also on a Canon camera. I used it on a 20D for some time and it worked fine: http://360impressions.de/Tower/http://360impressions.de/Mini1.html
