Want another body partly as back up and so I don't have to change lenses too much, my main interest is macro and wildlife though my time for wildlife is very limited with work I have a sigma 70mm macro, sigma 100-300 f4 and sigma 50mm 1.4 and will probably add another lens to cover everything. I bought a 5d classic as I would like to try ff but it was faulty so had to return it.Tbh apart from the sensor it felt a step backwards so would go for something more up to date but do It need ff? I don't print anything bigger than A4 size prints so would I really get any better iq thats noticeable than my 60d produces which is great when I get it right
