I would still buy this lens again, even with my experience with it. After 2 months, part of the lens loosened to the point, that it now rotates freely, and there are no longer reliable focus marking ( as that ring now spins free ) It only makes mounting the lens harder, and I cant use infinity focus...

Wide angle is a "must have" product for any photographer. Any scenes, city photos, night sky (this lens has very low coma, which is is excellent for astro photography). Smooth bokeh is good for macro photo. The only one drawback is absence of auto-focus.

Good lens for nightscapes (for a 24 mm only!), including the Milky Way. Possibility to see the Andromeda Galaxy ^^

I bought this lens to take photos of stars using my Pentax K-50. I haven't been in the position yet to do so, but I did try it out by taking some pictures of flowers. The quality was excellent.

I am using this lense with a Canon Rebel. I made the RIGHT choice with this lens as I was told by others that if I wanted the right combination of lense and sky, this was it....IT IS !!!

Bought this lens for a Nikon body and the performance of the lens has been stellar. I'm big into low light photography and am always looking at lenses that offer the best f stop range, so when I saw that this was an f/1.4 I knew I had to check it out. It works great.

Very sharp from corner to corner when stopped down to ƒ2.8, ƒ1.4-2.8 is still very sharp but hey, it's a very narrow DOF so what do you expect! Possibly THE best lens for astrophotography, no coma in the corners and CA (chromatic aberration) is very well controlled. Recommend it.

Really in love with this lens

20 July 2014

First impressions are that this is a well made, good quality lens; although quite large at around 102mm long and not light at 680g. In use the initial impressions are confirmed, it is capable of taking good quality, sharp pictures.

I have the lens a little over a year now. So I can give a fairly accurate review. I have used theis lens on my Canon with adapter, a Nikon D600, Red One MX and an Epic. If you use this lens with an APS-C sensor like all of the above with the exception of the D600. It is sharp corner to corner.
