Product Description


The Sigma 50mm f/1.4 EX DG HSM Autofocus Lens for Sony & Minolta is a high quality, professional optics and youll know it the minute you pick it up. In the past few years, camera manufacturers have overlooked the need for a reasonable fast prime lens that is compact enough for everyday use, yet provides the necessary image quality to meet the highest expectations. Now, with the advent of the APS-C cameras, the long popular 50mm focal length takes on double duty as a portrait length lens of approximately 90mm on most of the small chip cameras. At a fraction of the size, weight and cost of comparable lenses, this is a lens that you might have on your digital SLR at all times.

I bought this lens as my 6th 50mm lens. Granted 3 are Canon mount and the other three are Sony Alpha mount. I bought it because it was said to be sharp wide open - and it is! The only other 50 that is so is the Canon 50mm f2.5 [quasi] macro.

I love the color, contrast and sharpness of this lens on my A700. It is fast focusing and hits more than any other 50mm that I own. It is way more reliable than the Canon 50mm f1.4 for sure. From f2.8 on the Sony 50mm f1.4 is its equal and the Canon version is close. I choose this lens over my cz24-70mm f2.8 mostly due to the superior DOF and low light capability.

The only thing about this lens that might be a draw back is that it only only goes up to f16. If I need higher than that I have to use my Sony 50mm. Usually, I rarely go beyond f11.

I would recommend this lens to to anyone looking for a fast focusing, sharp and reliable 50mm.

Having feared Sigma's QC, I felt hesitant to purchase. This lens works perfectly and is the companion to my cz135mm. lens. I've had to take in my Nikon 70-200mm VI, and 24-70mm zooms to the repair center, the first for back focus, and the later for the known abrasive sound from the zoom ring, and for front focus. Both now are superb. The Sigma has been through two shoots and performed as expected. The bokeh is creamy, the resolution and detail is quite astounding looking at a Sony A900 file. This is the first outside party lens I have purchased, and I may look at the upcoming 85mm f/1.4 lens by Sigma also if it proves to be as good as the 50mm.

This lens attached to my Sony a77 is a match made in heaven. For low light shots, this lens is amazing. For portraits at 1.4, the DOF is great, creamy bokeh, sharp subject. Manual focus is easy and smooth, but auto focus is amazing. This is the only lens I own with a HSM focus system and it is amazing and quiet. The auto focus hits quick with the a77 and is 9/10 focused on the correct area. I don't know what else to say other than get this lens, it is a great lens sharp at 2.8, creamy bokeh from 1.4-2.0 (still great after 2.0, but 1.4-2.0 is butter) just get it stop going back and forth, it is worth every penny.

I am TOTALLY PLEASED by this excellent lens. It is FAR MORE than I had expected. I do appreciate the Sigma people for designing, manufacturing and presenting it to the photographic public.

I am an available light photographer. Although I do occasionally use flash, I generally prefer the much greater convenience and practicality of being able to photograph without the additional complications, limitations and expense of additional lighting equipment. Also, some venues prohibit flash.

So, this Sigma 50mm f/1,4 EX DG HS lens is a welcome solution.

This lens has been designed to be practical, durable, simple and easy to operate and reliable. The resulting photographs are superb. I intend to purchase Sigma photographic products again and again. And I intend to return to Amazon as my source.

The lens arrived quicker than I had expected. It was in excellent condition. I feel that the price was highly acceptable. The bottom line: for me, this was a FIVE STAR deal in every way.

Thank you much,

Neil Wilson

I bought this for my Sony A77 after doing my research and looking at sample shots versus the sony and minolta options. What I needed was a 1.4 that I could shoot at 1.4 and the Sony version was soft wide open. I read how this was sharp wide open and it really is. I dare say that this is one my sharpest lenses. The bokeh is really beautiful too.... very smooth. I read some complaints about focus issues, but mine has done a good job so far, even just using the center point. Its also very quick. I would buy this over the Sony version all over again.

This is a real world review of the sigma and more of a hands on for the Zeiss as I don't actually own it but I did take pictures with both lenses in the same setting at 1.4 on my a99 to develope my opinion. Now for the short story I would not spend $1,500 on the zeiss, not because I can't but because I don't think it is woth the money. Instead I would wait around for the 50mm art. Stick around if you want to know why.

First the Zeiss. It is better built and has weather sealing and the focus is quicker and more accurate think Sony 16-50. But honestly the sigma is build good enough and the focus speed is fine, if my subject is moving I will use a different lens. Like my tamron 24-70 or 70-200.

Now the sigma, build quality is fine, focus speed is fine. Good enough for slow moving targets or people standing still. Now I will say that the sigma has about a 75-80 percent accuracy rating. This is my one big problem with this lens. If that was not an issue this would be a great lens, but it is inaccurate enough to make me want to get a different 50. Now if you don't get paid to shoot this lens is fine and you could probably deal with the inaccuracys of this lens, but I get paid to shoot and this is a problem for me. Sometimes it great and sometimes it is like what just happened. Sometimes I have to focus 3 times before I can see that It got it. And I am using the center point for focus and am not moving during all 3 times and neither is my subject. If it was me I would know. I am very anal about my focus and I don't miss it with my other 6 lenses.

Now to the iq compairison. As far as sharpness goes. Based on testing at 1.4 I could not tell a difference at the center of the image. Now I didn't do a scientific test or take a picture of a brick wall.
