[49 mm (Front)] The size and weight is fantastic considering what it delivers. Makes it a wonderful walk around lens that can take amazing portraits when needed. If I just had one lens it'd be this one. And then I'd need another camera for my 70-180 tamron and i'd be set.

[Sony E] This standard fixed zoom lens is very sharp even with full aperture f/1.8. The optical quality is consistently supreme from f/1.8 to f/22, which most of other 50mm lens can not beat. I own a Canon 50mm f/1.2L, but that is not comparable even with aperture goes down to f/1.8. Except the Zeiss Otus 55mm f/1.4, so far this is the second best standard fixed zoom lens I have seen. Given its price and weight, Zeiss has done an amazing job!

[Full-Frame] Love the lens!

[9, Rounded] I use this lens as professional photographer, incredible Zeiss, and if you look a premium lens, I say get it!

[9, Rounded] I'm an old school photojournalist guy that back in the 80's would never have been caught dead with a 50mm lens of any kind. As I learned to do environmental portraits, especially in tight spaces later on doing corporate work, I discovered the 50 as a great lens for medium portraits and even for sports coverage. I really struggled pulling the trigger on a $1000 50mm lens but I did it and have not regretted the purchase. The 55 Sonnar constantly produces breathtakingly sharp images that even my clients notice. Hitting the zoom button on my A7 and A6000 is a pleasure as it's always shocking to see what kind of resolution you get even at 400%, on a preview image. The lens is not only sharp but also has excellent contrast and makes it easier in post to get the snappy images I like to make. combined with Sony's recent sensors, which are really great, the 55 combo on my A7 is a really nice way to work. I find myself reaching for the 55 on jobs when maybe I shouldn't--finding excuses to use it when another lens might be more appropriate. In short, it's worth the cash and I have no regrets...

[55mm] I really love this lens. It is the lens that is always on my A7. I rarely use any other lens. It is extremely crisp.

[9, Rounded] Like everyone else's reviews this LENS is great. Used it one several projects and the results are beautiful. I debated between this lens and the SONY GM 50 1.4 but I thought this was a better buy. Besides I did tons research and most of the reviews rate this lens very high. Also BH sales was very helpful in the decision making.

[0.14x] I have bought and sold numerous lenses from B&H as I am very picky on lens quality and sharpness. This lens had stayed on my camera constantly and the IQ is unsurpassed with any lens that has come and gone since. What a primo lens and worth the cost. If you are wanting one of the sharpest and quality built lenses sold today for Sony, you need this lens in your bag... but need it mostly on your camera!

[49 mm (Front)] This lens definitely lived up to its Zeiss name! Superbly sharp across all aperture and from center to edges. The bokeh is very nice and smooth as a 55mm lens and the colors look great.

I actually bought this lens instead of the 35mm and have not regretted it yet.

[8 x 4.4 x 4.3"] I have primarily used the lens for landscape work and some portraits. I bought this lens to compliment the 35 FE as well; I needed something longer and the 55mm fit perfect for my needs. I'm using the lens on the Sony A7R and the files are incredibly sharp especially stopped down. It has been coined the Otus lite by some and seeing specs for both I would agree. It's a very sharp lens. I don't worry about getting another stop out of it because I shoot at higher apertures mostly. The focus ring is very sensitive, it's easy to move it out of focus if you're not paying attention but that would be my only gripe. The 35mm is more stiff, which helps keep focus. It's built very well too. I really like the 35mm FE 2.8 because I enjoy the focal length but this lens exceeds another lens I have in terms of sharpness. If something happened to my 55, I wouldn't hesitate to buy another.
