I have been mulling whether it is worth getting a teleconverter or just buy a Super-Zoom P&S. I want to get into shooting birds, but I can't really get close enough with the SEL55210. I end up performing a huge crop, resulting in a mushy low-res picture. I have seen super-zooms do much better at the sacrifice of low-light and DOF. I was about the make the Super-zoom plunge, but someone I know sugested a teleconverter. However, I really can't a lot of quality stuff out there. The 2 that seem good are: The Sony DH1758 seems to be what everyone uses, but it is discontinued. I don't want to pay $200 to someone on ebay for a used lens that may be garbage. The Olympus TCon-17x seems to be viable, but I can't find more than a couple of examples of people using it on a NEX. Also, one guy said it was too heavy for the SEL55210. Can anyone recommend a 500mm+ setup for the NEX? Please provide examples if you can.
