User Reviews about Sigma 50mm f 2.8 EX DG Macro Lens for Pentax and Samsung SLR Cameras

This lens takes some of the best photos I have taken the color & crispness of shots is great both inside & out the detail of macro shots is great there may be a pro with somthing bad to say about this lens but for the money from beginer on up this lens is a must have. -- great lens

This is a great macro lens if you are on a budget. I was going back and forth between the Canon 50mm 2.5 and the 60mm 2.8. The Canon 50mm didn't have the greatest reviews and I didn't want to spend another $100 for the 60mm which is an EF-S lens. The Sigma is a very sharp lens along with some great colors and smooth silky bokeh. Perfect lens for weddings (rings) and flowers. It will work well for insects as well as long as you don't spook them by getting up-close. The auto-focus tends to take long to find the subject but no different than any other macro lens. It would be nice to be able to manually focus while in AF mode. The lens hood is worthless and annoying. You have to have the lens cap off to attach the hood. -- Great Budge Macro Lens

The Sigma's autofocus is nearly useless at 1:1, but many high end, dedicated macro lenses are manual focus only. For doing real close up work, I find manual focus is to be preferred; Autofocus is nothing but an annoying distraction.

I bought this lens to be used both for macro work and as a standard 50mm prime. When used at longer focal lengths the AF is fine. A bit slower than some of my other lenses but more than adequate. I have not noticed any focusing slip as one other reviewer noted. Perhaps I will with more use, but so far so good.

The images are crisp and detailed edge to edge. Although the least expensive lens I own it may well be the best for image quality! -- Great blend of performance and value

What a great value for the price! I would recommend that those of us on a budget could well afford to have this high quality lens in our bag for this price. I find that I am using it more and more and not just for maco photography. It is sharp and quick to focus. A bit of noise, but that is fine considering the results. It does exactly what I purchased it for. It is well built, sharp and affordable. -- Sigma 50mm f/2.8 EX DG Macro

I bought this lens for the macro capability, which worked out just fine, but what I soon discovered is that it is a great all around lens! This lens does a great job of portraits and just about anything else. If you want a good macro lens and something to keep on your camera for general purpose this 50mm is a bargain. The only thing that is a little aggravating is the switch you use to go from manual to auto focus, but it is really not a big deal. Hard to beat this one for the money. -- Great Purchase
