Just got the Rokinon FE8M-P 8mm F3.5 Fisheye Lens this month and am pretty excited about it, I shot a few images with it so far and overall very pleased with the results.
I am looking forward to going out with it to do some night time and also interior HDR scenes.
There are a few negatives that I found with this lens –
Chromatic Aberration, which I tame in Lightroom2 and Photoshop CS5, also when processing in Photomatix Pro I check the reduce Chromatic Aberrations box.
Close focus a bit fuzzy, I noticed when I have a subject in the scene too close about 2 or less feet it seems a bit fuzzy (even at f11) compared to the rest of the scene, but I think I have to fiddle with the focus more.
Manual focus, although with this kind of lens you can just set it in between and just shoot although as mentioned prior I think I need to tweak and test the focus setting a bit more.
And the plusses-
The price is not too bad – less than $300 dollars.
Dramatic views. This can really turn an ordinary scene into a really cool scene.
Fun lens!!! ah ok I said that already lol. But my impression overall is that it is indeed a fun lens.
Below are a few sample images that I shot so far. All were post processed in LR2 and also in addition some with Topaz Adjust and Nik Color Efex Pro as well.
In closing although I just barely begun using this lens I am really excited about it. This lens will be a regular addition in my camera bag.
