So... Today I woke up and decided I had enough time reading reviews, forums, browsing flickr for samples... And decided I would finally pull the trigger on a telephoto lens. As you can see from my sig, I currently cannot shoot past the 45mm focal length. I would like to start taking some different pictures, like going for a walk in the forest and shoot some birds, or squirrels. Do some landscape shoots with high compression. Go by the river and shoot some boats and water activities and go by the airport and do a bit of plane spotting. Now, the thing is I cannot make my mind between the Panasonic 100-300mm and keep it all m43 or go for the tamron 70-300 VC USD to use with my 350D. First the prices: - Panasonic 100-300 is 470 Euros. - Tamron 70-300 is 320 Euros. So, the panasonic is about 50% more expensive. If I go with the Panasonic, I will use it with my E-PL2. I was thinking about buying a OM-D but decided to hold on until the announcement of the new Panasonics, namely the G5 and GH3, to then decide which new body to go for. So I am really having a hard time deciding here... I guess my main concern is that because contrast detect AF is not good to track subjects, I won't get good pictures with the 100-300 and end up being frustrated... If I go with the Tamron, I might like it, but then I might start thinking about buying a new DSLR for it, since the 350D is pretty ancient and start getting GAS for a used 40D or a new 60D or whatever... I know the main thing is go out and take pictures and have fun, and that equipment is secondary, but I guess I am going through one of those times of reading reviews and reviews and forums and thinking about gear... Oh well... Can you help me out please! Thank you! Cheers!
