Wonderful lenses! Both of them are extraordinary. I havn't had time to test out the 70-200 but its sharp as a tack from what I've seen.
Heres a few pics from the 8mm, as I don't have any shots with the 70-200 I'd like to share yet. No critique please, as these are only for demonstration of the fisheye effect.
The photos really add attitude to your shots. Both of the animals are cats. Regular old cats. heavily distorted due to the lens. I have to say, it is a favorite lens of mine. Well worth the $650~ imo. Very sharp at F/5.6 and higher. 3.5 is good for 4x6" prints. The camera has the ability to have a 72mm filter added to the front by the use of a thread riser which mounts infront of the curved front element. It cuts some of your image out on the sides, but protects the lens better. I need to pick up a filter for this lens.
This is a 100% crop with my 70-200 @ 200mm, F/8, ISO1600, 1/4000th of a second. I know the values are all over the place, so don't mind that. I'll keep the 70-200 on all day tomorrow, I'll come back with more shots then.
This lens is tack sharp! I love the clarity I get when looking at any focal length throughout its range. Again, I'll have more shots with it tomorrow for those interested. Great lens, and it has great color too! The elements are perfect and I see canon includes less dust with their 70-200mm F/2.8L IS than they do with the kit 350D lens, 28-135mm and 400mm F/5.6L lenses.. Im planning on getting a polarizer for it, as well as a polarizer for my 400mm prime.
Let me know your thoughts on either lens and pros and cons I should pay attention to/take advantage of/avoid.
