Hi Evrim, Given your usual subjects and already owning some good solid primes that match up well for ballroom shots, street images and portraits, I'd consider keeping the EF 28-105USM for it's fast AF speed, low cost and the versatility. Obviously it can't reach out to 135mm but IMO even used at f/5.6 it's already to slow for typical 135mm uses like portraits, street shooting etc. (where I like to shoot very early or very late in the day/evening wide open), and at its best performing apertures, f/11-f/16, really quite slow for anything except broad daylight using moderate to fast ISO films. As you know, given a choice I'll take aperture over IS under most situations because I prefer the option of using higher shutter speeds vs. low shutter speeds. This leads to your second option, selling the 28-105USM and keeping the Tokina 28-80 2.8 or EF 28-135IS. I personally prefer the fastest, least amount of AF hunt possible and a fast f/2.8 aperture helps this under low light if you can retain cross type AF operation on your camera body. But the Tokina will not AF as fast as the 28-105USM or 28-135IS even in full daylight due to the lack of USM and from what I've read, slightly lower contrast. From my POV, between these two there's not much of a choice, the Tokina is a much faster lens it's sharper and perfectly usable at f/2.8 vs. the 28-135IS which is not in the same league in terms of optical quality, lens speed or build quality. Even with Canon's fast USM AF motors this lens' slower than f/2.8 lens speed will turn off the cross type AF sensor in most EOS bodies and probably only work at the same level under low light for which the 28-135IS lens is utterly unsuited. Granted the EF 28-135IS has quite a bit of reach, quite a bit more the Tokina's 80mm but it's of little value given the slow lens speed it's been encumbered with and the subjects you primarily shoot. Given your subjects and your style of shooting which is strongly emotive and interpretive I'd say having more image control is what you'll appreciate most and the Tokina 2.8 can offer more of it and is a sharper lens to boot. Also consider the EF 85 1.8USM and EF 50 1.8 when used on the D30 will effectively be fast 80mm and 135mm lenses. Add an EF 20 2.8USM and EF 35 f/2 both moderate cost lenses and you'll have the full range of classic street focal lengths (35mm, 50mm, 80mm, 135mm), for your D30. Crank it up to an EI of 400 for some atmospheric noise and be happy. On the longer end the 70-200 4L is a nice lens and probably somewhat less used then your middle length lenses given your subject matter. The EF 70-200 4L is a whole stop faster than the EF 28-135IS, MUCH sharper and is better suited overall for longer focal length shots IMO. So the 70-200 4L is a keeper, to date there's no substitute for focal length and lens speed when you need it and this is a very good performing lens for the money especially when you add an EF 1.4X to the mix.
