ok i want to get a wideangle/fisheye lens i was playing with the nikkor 10.5mm but it wont AF for me. i have a d40x. so then im looking at the sigma 10-20 but its only 102 degrees or the 12-24 which is 122 degrees and both will AF for me. what should i do. im thinking to maybe go with a sigma untill nikkon comes out with a 180 fisheye that will AF for me but when would that be? and which sigma should i get in the mean time? i currently have a 18-55 and 55-200 vr nikkor lens

The Sigma 10-20 is wider than the Sigma 12-24. If you were to use the Sigma 12-24 on a Canon 5D or another full frame cameras it would indeed have an angle of view as big as you mentioned. However, on a dSLR with a APS-C sized sensor it would give a angle of view smaller than that of the Sigma 10-20.

The Sigma 10-20 is a excellent lens. Sharp, contrasty, good build quality, great AF-speed, little CAs, though it does vignet a little.
The 12-24 is also good, but it is bigger, heavier, and does not allow you to use polarizing filters due to extreme lens design (Only colour filters at the back of the lens).

I think its pointless to wait until Nikon releases a 180 degree fisheye with AF-s motor. It might take a couple of years... If you really want a fisheye, you can also just use manual focus. Fisheyes have a huge depth of field, so focussing is not all that tough anyway.

Yeah, don't wait for Nikon. Either live without the AF on the 10.5 or get the 10-20/12-24 from Sigma/Nikon.

Theres always the Sigma 8mm which for a D40x would be a related to a 12mm on a full framed censor.

I bought the Tokina 10-17mm and I love it. It's got full 180 degree view at 10mm and will give full cover with your sensor

I posted some pics here.


I would certainly recommend it.

I know the 8mm won't work on your D40x. I was just pointing out the lens.

I think the 10-20 would be a very good buy, but that Tokina sounds kinda nice as well.
