Sigma - 28-135mm Macro Or Sigma 28-105mm Lens?

Mon Nov 25, 2002 10:38 am

I recently bought an SLR camera a few months ago, and am now looking into to getting some better lenses for it. The camera is a Canon Rebel 2000 (EOS 300) and came with a Canon 28-80mm lens. The lens is okay, but not great. I have already decided on a 300mm lens, but not on a replacement for the 80mm one. I have narrowed it down to two lenses. They are the Sigma - 28-135mm F3.8-5.6 IF Macro Lens and the Sigma - 28-105mm F2.8-4 Aspherical lens. Here are links to the Ritz Camera website so you can see some of the statistics: http://www.ritzcamera.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&catalogId=10001&langId=-1&productId=7465726&topCategory=1004&cat1=1022&cat2=914962 and http://www.ritzcamera.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&catalogId=10001&langId=-1&productId=7465721&topCategory=1004&cat1=1022&cat2=914962#description. Which one do you think is a better lens? What is most important to me is sharpness, so which one is sharper? How much sharper? Would this lens work well for very close up aviation photography? Would there be any other similarly priced lenses that you think are better? Also, in maybe a year or so, I would possibly like to upgrade to an Elan 7e (EOS 30) if I am really enjoying photography. I like it a lot now, but for me, that is a sizeable investment, so I want to really like it before I buy the Elan 7e. Would those lenses fit the Elan 7e? Thank you very much for your help!

First of all, yes, the lens mount is the same on all EOS models, so all lenses fit all cameras.

I have the 28-135mm lens on my EOS30, which I use for most of my general photography. I have a 70-200 and a 170-500 for aviation.

For the F2.8
  • The 28-105 should be better, being f2.8-4. Generally, an f2.8 lens used at f3.8 should be sharper than an f3.8 used at f3.8 since it is stopped down.

  • You also get the oppoptunity to shoot at F2.8 in low light.

  • F2.8 glass tends to be better.

  • The extra length from 105 to 135 is probably covered by your other longer lens.


  • For the F3.8
  • Lighter than an F2.8

  • Cheaper than an F2.8

  • Good 1:2 macro if you want it


  • Have a look at the reviews here.

    Thank you very much for your help  Smile! The 28-105mm lens sounds better for what I want, but I do have one question. What is vignetting? People complain about that with the 28-105mm lens at 28mm of zoom.

    Airplanetire,

    Notice on the photo below how it gets darker towards the corners, that is vignetting. It usually happens when you use cheaper lenses with the aperture wide open. Closing it down a stop or two usually gets rid of it.
