Would you consider a super zoom lens over a good Bridge camera, where image quality is concerned?
More specifically, I am looking to get a Fugifilm X-S1 which goes from 24-640mm and gets very good reviews/feedback; minus initial releases which had a sensor and lens droop issue. We just got a Canon sx-40 and I'm impressed with the image quality in comparison to our former sx-1 and sx-10. The Fugifilm is supposed to be even better given it is a 2/3 sensor camera.
However, I've also considered the new Tamron 18-270mm pzd which would be equivalent to 432mm on my 40d.
I have my short ranges and quality covered with Tamron 28-75mm 2.8 and Canon 15-85mm but need something for the long end and would like versatility, so the 70-300's are out. 70mm just isn't wide enough as a "do-all" walk around for me.
