Thanks all for your suggestions. Actually I do have a 50 f/1.8 (beside the 28-80 kit lens), and really love it...

I was asking about these Tamrons because I saw them on B&H catelog, which fell into my budget. As a beginner and definitely an amateur later, it's hard for me to justify a bigger budget, particularly for a tele, which I probably don't use that much...

From the review on this site, Canon 80-200 sounds pretty bad (as good as my kit lens, I guess). How does it really compare to a 75-300 in terms of image quality? The latter (non-IS) is still within my budget.

I'm thinking about a zoom tele lens for landscape and possibly for

portrait. I guess I can live with manual focus to save some money.

There are 3 Tamron lenses (used, with adapt-all mount) that look

promising:

80-210 f/3.8-4

70-210 f/3.8-4

70-210 f/3.5 SP

Does anyone have experience with these lenses? How good is the image

quality of each one of them? How do they compare to Canon 75-300

f/4-5.6? Btw, my budget is $200. Thank you.

I have a Canon Elan IIe. But I cannot make the kit lens, EF 28-80mm

f/3.5-5.6 working with depth of field preview (DOFP), either by eye

control or using AE/CF/DOFP button when custom function (CF) 04 set to

2. In both cases, my EF 50mm f/1.8 works fine. My understaning is that

DOFP is purely a function of the camera body, not that of lenses. So

what went wrong? Please give me some advice. Thank you.
