I was looking for a prime lens with macro capability and since I already had the Pentax 50mm f/1.4, I needed something in the 100mm range. There were two options: this Sigma and the Pentax equivalent that was slightly more expensive. I've seen some great recommendations for the Sigma on photo.net, so I decided to go with it and I don't regret that choice. If you've been using cheaper lenses, this lens will show you why it's worth investing more into a good prime lens. I've been using it for macro photography (flowers) and for portraits with great results. I also recommend the Sigma DG 58mm Multi-Coated UV Filter to go with it.

I use this lens daily in my dental office with a ring flash. It is big and heavy but takes great pictures. It is not a versatile photo item and has specific uses. I would not take it on vacation but it is excellent for telephoto, portrait or close-up, macro photos. It works well with the auto focus system on my Pentax 200D. Because of it's size, I suspect it will use up battery power very quickly if you use it with auto focus and it is forced to move alot. I use it in manual focus and just move forward or backward to get a sharp image.

If you wanted to try out some true macro photography this is good lens to start with. It provides a decent working distance to the subjects and also doubles as a very nice portrait lens. It's quite sharp even wide open and it renders colors and blur very well.

excellent product with excellent service from the supplier. My son loves his new lens. Far exceeds expectation.
