You said the magic words – under $750 and 30D.
As I started in DSLR, I read the forums and the reviews quite a bit. I decided that I would have enough problems with my capabilities without worrying about the weaknesses of my lens, so I decided to skip the kit lens. Now it’s back to the reviews.
I wanted a fairly versatile lens – preferably about 10-800/f1.4, sharp at all apertures and all ranges. Oh, and it should be ‘L’ quality for under $500. I couldn’t find it.
Initially I was very impressed with the range of the Sigma or Tamron 18-200 lenses, but if they won’t focus properly and are soft at many areas, what good are they? Back to the reviews . .
Since I wanted a range of views from wide-angle to telephoto, I quickly narrowed my search down to the Canon 17-85/4-5.6 ($510), the Tamron 17-50/2.8 ($450), and the Sigma 17-70/2.8-4.5 ($389). All of these lenses do well on the reviews on image quality, focusing accuracy, and solid lens construction.
The IS on the Canon was very attractive, and the constant f2.8 of the Tamron looked very useful, particularly for indoor events. But I finally decided on the Sigma 17-70. For me this lens has a very nice everyday range, from medium wide-angle to mild telephoto (effective 27 mm-112 mm on a 1.6 crop camera). I like the wide aperture at the wide angle, where I’m most likely to need it – close quarters indoors. I also liked the idea of the semi-macro capability – 1:2.3, which I’ve found quite satisfactory for a LOT of wildflowers. Although I have additional lenses now, the 17-70 stays on my camera 75% of the time.
And let’s not forget portraits – get the Canon 50/1.8. It costs about $80, and is an under priced jewel. Great for low-light, such as museums which don’t allow flash, and quite nice for portraiture. It’s effectively 80 mm for the crop cameras, and shooting at wide aperture does an excellent job of fuzzing out the background, emphasizing the subject quite well.
Note – please take a few minutes to think about your long-term plans and how the lens you purchase now will fit into that plan. I determined that I wanted to be able to cover from extreme wide-angel to medium telephoto. With additional lens purchases, my focal length coverage is now from 10 mm (effective 16 mm) to 300 mm (effective 480 mm) with no gaps (10-20, 17-70, 70-300). I honestly don’t think I’d miss a small gap here and there, as I would have had if I had chosen the Tamron 17-50, but there is a pleasing symmetry knowing that if you’re stuck in a particular position, such as a zoo railing, you can still frame as you want.
