wanting to get into astrophotography i did my research and found out the samyang 10mm f 2.8 would be a pretty good lens for my maybe not so good camera, nikon d3300. However it seems i somehow bought the "cine" version of the lens. which has a T number of 3.1 instead of an F number of 2.8. I am really conflicted whether or not i should send it back and buy the other version, the weird thing is that the "cine" version i bought was 80 euros cheaper than the other one. Are there any problems using a cine lens for photography? And does the T number of 3.1 work as well as an f 2.8 when doing night photography? The 2 lenses have pretty much the same weight and measures, so is it basically just the same lens? I know the cine lens has an aperture ring with no stops, but i dont know if it is different in any other ways. Any help is greatly appreciated, thanks in advance!
