Canon EF 15mm f/2.8 Fisheye

Pros: Optical quality at f/2.8 PERFECT! Is there anything else I should know? The price is a bargain.

Cons: Fisheye distortion, but if you do not abuse it is perfect

Opinion: I had borrowed from a friend and I used it for night shots to the stars. The quality is really perfect until the corners even at full aperture and full frame. To my knowledge, there are similar objectives for canon with this quality and focus, especially among those in the rectangular projection of which are disappointing on the stars.

Canon 60Da

Pros: Simple, for the whole family, great compromise for day / night.

Cons: Sensibility to red not like a baader changed, possible mismatches color in special situations (but rare, I do not I've never seen).

Opinion: Excellent for the novice astrophotographer who want a car for the family, without the complications of a modified, and at the same time wants to use it to shoot the red nebulae in a decente.rnLa sensitivity in the red h-alpha is not equal to an adjusted room with baader.rnRecensione complete filter: http://www.juzaphoto.com/topic2.php?l=it&f=23&t=212112

Tokina AT-X Pro 11-16mm f/2.8 DX

Pros: Short throw, brightness, rectangular projection

Cons: I had problems on 5 different specimens, strength, flare, chromatic, coma

Opinion: It is now the fifth example of this approach, the paper good for the purpose for which I took, or astrophotography, large fields, timelapse. The first two examples arrived, new, had the focus locked, impossible to bring the ring to auto. The third is mechanically broken after a few days of use, at the beginning of a trip abroad where he was to be a highlight. Repaired in service but the result of focus. Replaced with a new one, but did not come to focus to infinity. Finally replaced with another (my fifth copy) and ok only at the center and left, while on the right is completely blurred. I know that if further tests conformed to the problem, I will also return this copy ... bah ... The service was excellent, replacing the lens several times, but apparently the production Tokina leaves much to be desired.
