Hi all, Hope people can help me out with my buying strategy for lenses. I got the Nex 3 kit new for 140€ including the 18-55 lens. Its great fun so far. The pictures taken indoors without flash or in lowlight are much better than my compact. I use my camera when on holiday to take the pictures of the sights. But mostly its to take pictures of family gatherings. So lots of people, kids indoors at lowlight. my friend told me its a good idea to buy a fast prime for this. What was shocking to me was the prices of the lenses. Much more expensive than expected. So with my budget i will need help with choosing the addons that fits with my need. 1) A friend is giving me his olympus OM 50 1.8. Just waiting for my 10$ adapter from ebay. Lens seems as fast as teh Sel50f18. just no OSS. but much much cheaper of course. \is this good enough as my fast prime lens? 2) Sigma 30mm 2.8. Great reviews and even greater price. Just 128$ here. Cheapest lens available. i love the focus length. Only i am not sure if its fast enough for lowlight pictures? otherwise it would be perfect prime. 3) Sony Sel 16f28, available for 123$ via ebay. Reviews are not great..but what makes it so interesting are the adapters. Wideangle and fisheye for about 146$ per adapter. Making it quite versatile and cheap.I ave no idea how use full these adapters will be. pretty great value.Consideirng how expensive the seperate lenses would be. 4) lastly the 55-200MM. Would it be better to buy this? perfect complement to my kitlens. looking forward to your advice and input.
