I'm generally delighted when people use my photographs under the Creative Commons by-nc-sa license. "Photo by Glen K. Peterson" is the appropriate credit. If you find that license too restrictive, just tell me what you are planning and ask for more rights and we can work something out. I always love to see the finished result!

Since April 2009, I've been using a Canon 40D with:

Canon 24mm f2.8 - nice, but gives significant barrel distortion making anything that dominates the frame look bulbous.

Canon 100mm f2.8 macro - OK, but only sharp from f4-f11, making it kind of a poor choice for macro.

Canon 50mm f1.4 - best lens I've ever owned. Tack sharp from f2.8-f16. Great for macro (with extension tubes) at f16, great bokeh at f1.4 for portraits.

Canon EF 100-300mm f5.6 L - At 300mm, it gives a soft-focus until f9. Otherwise, the quality is excellent for a zoom. Not sure why Canon didn't put a rotating tripod collar on this lens.

Canon EF 28-105mm f3.5-4.5 - quality is good, but not as good as a prime. Looks a little like shooting through cellophane.

Tokina 400mm f8 - grainy, not super-sharp, poor contrast, with strong cyan/magenta borders of highlights (chromatic aberration). Still, it's 400mm and has a rotating tripod collar so I use it for birds sometimes.

Kenko extension tubes.

Earlier pictures are taken with a Nikon D50 using:

- Nikon Nikkor 60mm f2.6 macro (1/1). My best Nikon lens. Pin-sharp at f11. Only complaint is that the front element is recessed, making lighting difficult with 68mm of extension tubes.

- Nikkor 24-85 f2.8-4 - It's not as sharp as the Nikkor 60mm, but the quality is still very good and the zoom feature is so handy that this is rapidly becoming my most used lens.

- Tamron 28-70mm f3.5-4.5. Blurry, poor color and contrast, and all the movable parts were loose.

- Nikon 70-210mm f4-5.6. Tends to produce some weird cyan/magenta highlights on back-lit subjects at 210mm. It's fairly sharp, but could be better. Using it with extention tubes makes it look grainy somehow. I wish it had a rotating tripod mount!

- 500mm f18 POS
