Love the photo's you posted with the fisheye Samyang lens, utterly superb!
Are they shot with a full-frame or cropped sensor camera??
Thanks for the comments guys! This lens has been a great addition to my bag. The build quality is awesome and really can't complain about anything. I really believe this lens can be used for just about any subject if the subject is properly placed in the composition. I shoot with a Canon 7D (Crop Sensor), so I do not have any issues with vignetting. I believe the FF body's have this issue which requires you to crop the sides.
