Summary: The only reason that I have given this lens a four star rating is due to the fact that this is the older model of this lens and I purchased it used from a seller on Amazon.com. Had some trepidations about buying something of this nature used and unseen. Must say that I was pleasantly surprised at the condition and cleanliness of lens, well taken care of. Will be looking at used lenses in the future. As stated this is the older model Sigma 105mm macro lens.
I paid $90. After trying it out, I called my buddy and told him to get one

Summary: I purchased this as my 3rd Sigma out of 12 lenses. I wanted an all-around, full frame, light, fast to reasonably fast zoom, knowing that the sweet spot will never be 2.8 but hopefully it will be no greater than a 4. I got mine for under $90.00 including shipping. It is a primarily plastic, and I like it best around F4.
Summary: I am not a professional photography by any means. I bought my Canon camera less then a year ago and I knew I wanted to do some macro photography. I read a lot of reviews before buying this lens. I did not have a whole lot of money to spend on a lens so I went with this one because of the price and the reviews. This lens I believe is well built. I have taken some really nie crisp photos with it.
Summary: I paid $380 for a used lens that looked brand new out the box. At that price I had to buy it. The lens takes great pictures but it is a subsitute for the Nikon VR 105mm. The virbration reduction is the only thing missing. I have to shoot more off the tripod for shots like ring and marco shoots. The Nikon lens saves me a little more time. If you have the money buy the Nikon lens. However, If money is a concern the Sigma 105 is a great buy.
Summary: I did my research before settling on this lens. I knew I wanted a mid-tele macro instead of a shorter version. The focal distance for the shorter macro lenses seems unrealistic - how can you get the lens out of the way of the shot? I knew I wanted at least a 100mm, so it was between this and the Nikon 105mm Micro/macro.
Summary: This is a great lens! Build quality is not Pro level, but optics are darn close! CA/PF rears its ugly head a bit, but nothing too major. If you can find one at a decent price, get it, you won't be disappointed!
Summary: I read too many blogs and magazines to finally decide upon this lens as the best quality/dollar in a macro for my serious amateur ways. I considered the 60mm nikon, but ultimately wanted the ability to shoot a little farther away from my subjects and the prospect of having a decent portrait lens appealed to me. Reviews say the quality of the glass is better in this older model than the newer model and I can say it's super sharp even when shooting wide open.
