Nah, I'm getting the 100l macro, and I'll be back to show how it's faired for me. I'll take it purely because it is sealed, and the IS, as I plan on using this lens a lot and 300 bucks is nothing if I compare it to the amount of frustration I'd get from motion blurred images over the years.
180mm is not suitable for full body shots due to my studio size, if I had a bigger studio, I might have considered it. And also no IS at 180mm? I don't think I could handle that.
200 is way too long to be my workhorse, not to mention the lack o IS, but given the image quality/price point, I'd be tempted to get it rather than a zoom as my tele-lens.
I'll get something more compressed later. Probably the 70-200 with IS. I played with my lens with IS OFF, and it really is a must have feature on any lens.
I've shot with TS-E 90 and I loved it, but it is really only suitable to shoot fashion if model is sitting down and you're shooting from a tripod, as focus is crucial in modern photography.
There are plenty of current editorials that benefit from "focal plane" of the tilt shift lens.
It's just that those knobs on Canon are way to small for my taste.
And, as it is MF, there really is no reason for anyone into tilt not to just purchase a used lens and use an adaptor for their camera.
