....you lose features?
I'll provide and example. Recently, I owned both a 7D and a 5D II. The 5D II had nice images with better sharpness and noise handling. However, the 7D beat it in almost every other single category. The dial wheel on the 5D II felt cheap. So did the spiked wheel near the shutter. The 7D felt much better in my hands and was more responsive. By upgrading, I'd also give up perceived reach. My 300 prime is at 4@480mm (INVALID EMAIL) on the 7D. To even reach 420 on the 5D II, I'd need the prime and TC, and I've be at 5.6.
In the end, it didn't feel like a $1000 "upgrade". Yes, the sensor was superior. But I'd have to go backwards in some areas to move forward. I'm not sure if that's ever an "upgrade".
The same applies to this Sigma 8-16 I'm looking at. Awesome lens with amazing reviews. However, it can't use filters. If I "upgrade" my 10-20 to the 8-16, I lose an important component of my photography--using a CP for wide angle shots of water scenes. So is it really an upgrade?
Anyway, something to think about. Sometimes the best move we make, is none at all.
