Hi, First of all, I thank to all people who answered my EOS 3 exposure question. It was most helpful. I will have my test slides back from the lab soon, so I will let you know the results.
>I'm looking for a good tele-zoom to add to my EOS 30 with 28-135 USM IS >lens. Sadly, my budget (and wife) doesn't allow for a 70-200 f/2.8 USM L >IS so I have the following options: > >70-200 f/4 USM L >OR >75-300 f/4-5.6 IS USM The appropriate zoom is a problem for me, too. I need at least 300 at the long end because it is necessary for wildlife photography. But in the case of telezooms there is no such an affordable compromise like the 28-105 among the wide angle zooms (between the kit lenses and pro zooms). I need a quick solution but now I can't afford a 100-300 L. I found the following lenses: Canon 75-300/4-5,6 (III/USM/USM IS - optically equvivalent) Canon 100-300/4-5,6 USM Sigma 75-300 DL or APO macro /4-5,6 All of them is consumer grade lens and is said to be soft between 200-300. The Canon 75-300 has an extending/rotating front element. The build quality is poor. But the USM motor is fast. Lightweight. The Canon 100-300 has much nicer build, non-rotating front element, ring USM. It is significantly heavier, disadvantage if you take it in your backpack to the mountains. I thought that its optical performance is better but, to my amazement, some people stated that it is softer at the long end. I don't really know the Sigma lenses. Rotating front element, slow and noisy AF, slightly more weight and better build quality than Canon 75-300. Macro feature at 300 - said to be nice for butterfly photography. Some people say that the APO version, which has better color reproduction, is less sharp than DL. Their optical quality maybe like the 75-300. Hard to decide.
