I recently bought a Novoflex "EOS-RETRO" Lens Reverse Adaptor which retains all EOS lens functionality (including autofocus). The standard thread fitting is 58mm, although standard stepped adaptors can be used. I have been using the Novoflex with a 50mmf1.4, and intend to buy another prime (probably 28mm) to extend my capabilities. But I would like to experiment with the flexibility that a zoom offers. The subjects will vary, as I am experimenting at this time. The only zoom that I have is the 28-135 IS (72mm thread). My questions are: (1) What would be the effect of using the 28-135 IS in terms of picture quality (naturally I would need to buy a 58-72 step-up ring)? (2) What fairly cheap used EOS zoom would readers recommend to buy that would be capable of achieving quality approaching a prime? BTW, previously I have been a reverse lens adaptors with my F-1 and 20, 24, 35, and 50mm primes.
