8-15mm or 15mm fisheye?
« on: April 11, 2013, 10:22:19 AM »
Hey guys,

Just a quick question... I did try looking but there seems to be a fair bit of conflicting info on both these lens... I have at the moment a Canon 15mm 2.8 fisheye. I am looking to use this as my main surf lens in my water proof housing... I have read that the 15mm suffers a lot from CA and that the autofocus isn't very good, to be honest I have never noticed it... My girlfriend really wants to buy my 15mm off me which is why I was looking at the 8-15mm. Am I going to be better off keeping the 15mm or will the L lens make a night and day difference?

Cheers
Alex

According to TDP, the 8-15 should be sharper outside the center (might help if you defish)  and it should be better against flare.

If you're happy with the 15mm, I don't think you'll be blown away with the 8-15's advantages for twice the price.  One of the advantages of the 8-15 is the flexibility you have with crop and FF bodies.  You can get a wider AOV with the crop, and you can get the porthole look with FF.  I don't use the porthole look much but changing the AOV on the crop is a nice feature.  I've unloaded the crop camera since moving FF, but I can imagine that the 8-15 would be a lot more valuable to someone that has both types of cameras.  You might have to try renting it out to see if it makes sense to you.
