1. Sigma 15-30mm f/3.5-4.5 EX DG IF Aspherical Ultra Wide Angle Zoom Lens for Canon SLR CamerasI am a pro shooter work for several papers and celebrities as well and I take this everywhere.
   This is the best lens for the price. I have used this lens on my 1Ds & 30D and performed remarkably. I also Had the same one when I was a Nikon shooter in fact I only had one glass that was not Nikon and this was it. I have never worried about it failing on me at all and it covers the full frame digitals as well as the 1.6x factor. It is sharp as a tack in all ranges for me that is even better than my 28-70 2.8 L series lens from Canon. It is Rough and can take a beating, so if you are looking for a lens that does not cost an arm and a leg and will perform in all conditions this is the one for you in Nikon or Canon.

1. This is one fantastic lens. It is BIG, built like TWO TANKS, and takes gorgeous gorgeous shots. I bought this lens after a year or so of excellent results from its smaller sibling, the venerable 105mm macro. I thought it would be useful to get the extra working distance that the 180 affords. I can say with certainty that the longer focal length is a dream come true. You get so close up to your subject without being right "in it." I had imagined that this would be a "tripod only" lens as it is hard to hold a large lens steady. I have been amazed at my hand held shots coupled with my Konica Minolta 5d (in body image stabilization surely helps!). I have taken excellent tack sharp images hand held with shutter speeds as low as 1/25 at ISO 100. I don't regard myself as a particularly steady hand either. Color is great, sharpness is superb, accessories (case, hood, & tripod collar) are all first rate. Most importantly, photo colleagues are as enthusiastic as I am (more so I suppose) about the results. You won't be disappointed if you can find one for your KM 5d, 7d, or Sony A100! By the way, them Minolta /Sony mount of this lens is NOT HSM, you know that. AF with macro lenses is tough anyway, you know that, right? Right! Even without HSM, AF is better than on the 105mm. Enjoy!
