Excerpt: I broke new ground with this purchase; buying a 3rd party lens. Well, not entirely true, I do have a vintage soviet lens but that's an entirely different purpose lens. My main interest is landscape, waterscape, night and some astrophotography, aurora borealis, nature, macro, some architecture, etc.
Pros: Close focusing, Excellent Rendering, Lightweight, Nice Bokeh, Nice Focusing Ring
Excerpt: 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.
Pros: Consistent Output, Lightweight, Strong Construction
Excerpt: 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.
Pros: Consistent Output, Easily Interchangeable, Low Light, Strong Construction
Excerpt: I purchased this lens primarily for astro-imaging after acquiring the Bower 8mm and Samyang 85mm; both of which yield great stars edge-to-edge on an APS-C sensor. The 24mm lens is not as good BUT still usable if one doesn't mind knocking 10% off the edges...
Pros: Easily Interchangeable, Nice Bokeh, Strong Construction
Summary: 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.
Excerpt: Deze lens is door zijn handmatige instelbaarheid zeer geschikt voor gescripte video-opnames en fotografie vanaf statief. Samen met een goede variabele ND-filter (ik kocht de Heliopan) zijn mooie onscherpe achtergronden te creeren.
