FZ35 vs 55-210 on NEX 5N-- a little math help
I have a Panasonic FZ35 superzoom and recently acquired a Sony NEX 5N (still researching and determining if I want to get a DSLR also, but that's a different thread :-)). I don't use the FZ35 much these days as I don't need the long end much, but it is useful when going on a vacation where I might be seeing/viewing wildlife and if going to a zoo, etc.
I'm wondering if I should sell the FZ35 and buy the Sony 55-210 mm lens for the NEX. Essentially, would the results be better on the NEX even though the reach is not as far?
The FZ35 has a 486mm equivalent 2.8 - 4.4 lens and a 12.1 megapixel point and shoot-sized sensor.
The Sony 55-210 would give 315mm equivalent on the long side and has an aperture range of 3.5 - 5.6, of course with a much larger APS-C 16.1 mp sensor. I figure that given the much higher ISO ability, larger sensor and additional megapixels I should be able to crop and get an image on the 5N that is significantly better than the FZ35 even though the lens is a little slower.
Am I thinking about this correctly?
