I've been a serious amateur for about 10 years now.. Â i have a canon 50D right now, with a few lenses....70-200/2.8, 16-35/2.8 and 24-70/2.8. Â I also have a 50/1.4 ....these 4 lenses suit almost all of my needs, but i do want an extension tube as well. Â I do it for me...although I have easily filled the house and countless others with pics, and i mat everything myself so its quite easy to get that done with my preferred cropping :) Â I base my lens preference beautiful bokeh :) Â i would never stray from canon or nikon, but have committed to canon and never had to question that, fortunately.
