Canon 60mm macro vs. Sigma 70mm?

Discussion in 'Canon EOS' started by tom_worster, Apr 2, 2008.

  1. The reviews at pop photo and photozone give the Sigma the edge in image quality -- the Canon vignettes wide open and the Sigma is sharper off-center -- though both are clearly very good. Advantages to the Canon are USM autofocus (faster, quieter) and that it doesn't extend when focusing, which should help keep dust out. Thoughts?
  2. You nailed it, optical quality vs USM. Which is more important to you?
  3. In this instance I'd go for the Canon. For macro work you won't be shooting wide open and for potrait work vignetting won't matter as much and you will want USM. The Canon is reportedly very sharp anyway so evn if the Sigma is a bit better it may not be noticeable in practice. My impression is that Sigma suffers a little bit more in terms of quality control too. Finally I much prefer internal focus designs, not just for dust but also for handling.
  4. Ps I should add that I would and did actually go for the Canon 100 f2.8 macro. It is bigger, heavier and more expensive than the 60/2.8 macro but I prefer the longer working distance both for macro and portrait work as well as the focus limiter.
  5. The PZ test leaves little to be desired. Also, USM and IF/RF mean a lot to me, even in macro. I have the 100/2.8 and toying with the idea of adding the 60/2.8 as well. The Sigma 70/2.8 is not even a consideration.
    But as always, YMMV.
    Happy shooting,
  6. Just one thought to be added to the mentioned tests at PZ ... these tests are done with focus at (or near) infinity. Eventually the situation in the macrorange isn't the same. I would still think that both are very decent lenses, but for macro work, you shouldn't derive too much from these tests.
  7. None of the pictures I saw on the web indicated that it is anything but excellent in macro shots. Happy shooting, Yakim.
  8. Hi, here is another link that has a Canon EF-S 60mm Macro review. Best
  9. What are the trade-offs of the Canon 60 vs 100 macros? Even more than close-up photos, I'll be shooting ceramics typically between about 4" and 16" high. Maximizing depth of field is very important. Do I get more DOF with the 60 and the camera closer to the subject that with the 100?
  10. DOF is the same. For all practical purposes, at the same macro magnification, DOF is always the same whatever lens you use. You may be able to influence it a fraction by using retrofocus or telphoto lenses with a pupil magnification other than 1, but generally speaking with "normal" lenses, DOF is pretty much identical at the same magnification ratio. The 60 is smaller, lighter and cheaper. The 100 gives you more working distance and covers full frame.
  11. "What are the trade-offs of the Canon 60 vs 100 macros?" Mostly working distance and some features like focus range limiter and the possibility of using a tripod ring. More apparant background blur due to percepective "I'll be shooting ceramics typically between about 4" and 16" high" For insects the 100mm would be recommended but for quite big objects like those something around 50mm is probably best unless you hav a lot of room. If you are working with a plain backdrop you don't need to consider the percepective advantage. "Do I get more DOF with the 60" At closeup and macro distance DOF is independent of focal length for a given effective (not set) f-stop and framing. Some info on Canon macro equipment
  12. >> More apparant background blur due to percepective Which is important for isolating your subject from the background. Happy shooting, Yakim.
  13. I checked at that DOF is exactly the same (0.9ft at f/8) for a subject at 10ft with a 100mm lens and a subject at 6ft with a 60mm lens.
  14. "Which is important for isolating your subject from the background. " Hmmm, I thought the OP might understand the implicit point. It sounds like they are studio working anyway so than can just use a backdrop.
  15. lester, yakim: i think i understand your point now. i saw 3 photos comparing the same close-up scene with 3 focal lengths, i thought the smoother blur of the background indicated smaller DOF, thinking that wide angle lenses have bigger DOF. but eventually i figured that's only true if you don't move the camera to frame the subject the same. so now i get it that it's the narrower perspective that achieves the additional blur. it's true that we will be using backdrops. even so the blur is good to hide the surface texture of the backdrop. but i'll choose between 60 and 100 by taking some pictures of pieces of various sizes with the zoom lens to decide whether i want more or less perspective on the subject. the pieces, like the example photo i posted above, mostly have significant depth which needs to be properly represented. 100mm lens on an aps camera is like 160mm on 35mm which might flatten things too much.
