So I want to get one of those funny looking do-it-all lenses... zooms is what they call them, right? Seriously, I've come to the point where I am happy with what I have (considering the budget) but for the first time in forever I find myself wishing I had one lens that could do most of shooting, at least in certain situations. I have looked around and pretty much nailed these two down for final consideration: Nikon 28-105 f/3.5-4.5 and Tamron 24-135 f/3.5-5.6 The usual question: Which one do you prefer at their common focal lengths? Even if you have used only one of these, it's fine to leave your comment on it and I will try to cram it all into one useful piece of information (or I will just flip a coin, depends on moon phase). What I "know" is that the Nikon is excellent. I also "know" that the Tamron is excellent and that is very good at 24mm, which I like a lot (wide end is more important to me than long). I have no idea how they compare in build, feel while zooming dnd manually focusing... but I do know that Nikon costs about 50% more. My wishes/requirements, in case you have some other ideas. - I want it to work with both film and digital, so it must have the aperture ring. My cameras are FM2n, F3, F100 and D90. - Manual is ok, though since I am trying to provide myself with an easy shooting option, AF feels much more appropriate. Obviously, the lens MUST have the possibility for manual focusing. - Ideally, the zoom would start BELOW 28mm. - This will not be my primary shooting lens, so I don't care for lenses that cost more than $200. These two can be had in the 100-150 range, in excellent condition. Thanks!
