Terry posted in another thread how she used the 100-300mm Panasonic on safari and was now testing out the Nikon 70-200/2.8 on the V1. I wanted to continue the discussion started by the following three posts without taking that other thread off track:
It's interesting to compare the 10MP Nikon V1, 16MP Panasonic G3, and 24MP Sony NEX-7. On the face of it, we have 2.7X, 2.0X, and 1.5X crop systems. However, if we crop the Panasonic and Sony sensors to 10MP each, then on the basis of the resulting sensor area, we get 2.7X, 2.6X, and 2.5X crop systems, respectively. Very little difference.
At that point, the effective reach is more a function of which system has a lens that can outresolve the sensor. Of course there are operational issues (VR, AF performance) which may prove even more important.
Hmmm, but how about a NEX with adapter and the nice Sony 70-300G? Not long enough?
Correct - I did 75% or more of my Kenya shots at 600mm or longer.
So, Nikon gives me two extra stops (I know partially offset by good high ISO on the NEX 5n and cropability of the NEX 7). We shall see how this goes. I was really just looking to take advantage of the crop sensor of the Nikon and then the extra DOF that comes along with it.
As Jan alludes to, crop sensors can give more effective reach because of smaller pixel pitch. Ie, there is nothing specific about the sensor size itself that gives more reach.I wonder how the V1 with a Nikon tele compares to the NEX7 with a similar lens (like the Sony 70-200/2.8G) cropped a little bit?
