That's... Not.. How.. Crop factors... WORK

The only advantage you get over just cropping through using a small sensor is pixel density, but that doesn't matter when you're using a cheap lens that isn't anywhere near approaching the resolving power of the sensor.

Getting back into it again mate? You and me both! I purchased a 600D, have the 18-55mm and a 50mm 1.8! Have just been given a 80-200mm lense for free but it has no IS and I don't have steady hands!

Let me know which lens you go with as I'm interested in replacing my 80-200mm with something with stabilisation!

One of the cheapest ways to get extreme reach with decent image quality is to use a Nikon V1 + FT-1 adaptor and whichever f-mount lens you choose.

It retains full AF & metering with no loss of light and because of the 2.7x crop factor, the cheap Nikon 55-300 VR (as an example) would become a very powerful 150-810mm with stabilisation.

The V1 has a 60 fps burst as well which is great for birds!

This x1000
There is simply no better setup for birding without spending a fortune.
Nikon even released a 70-300 CX lens.

No, the end result is a mediocre 150-810mm field of view with stabilisation and the image quality of a massively over-cropped cheap 55-300, without the AF performance for birding and with a really weird front-heavy balance .

Not at all true really.

Plenty of pros using a Nikon 1 with 70-300 as a backup solution or for a lighter setup.
Thom Hogan raves about that setup; you get good results overal, tremendous reach, great image quality (sufficiently resolving feather detail), and AF close to DSLRs.

Don't under estimate the Nikon 1s. They have their issues (no serious camera with appropriate controls) but image quality is similar to previous gen DSLRs, autofocus is similar to modern DSLRs, they are amongst the fastest cameras around and the ft1 adapter is by far the best adapter.

When it comes to wildlife pixel density is very important and although it is surprise the Nikon 70-300Vr does resolve plenty of detail in the centre covered by the Nikon 1 sensor. It is actually a very sharp lens overall, in the 70-200mm range it is just as sharp as my Nikon 70-200mm f/2.8 VR1

Hi Mike.yes getting back into it:).i eventually bought a new 55-250 ii is for £110 and I really find it good for my needs.havent managed to shoot any birds close up yet but with the lens and a crop should satisfy me for now. and if you put it on the tripod that should help:).

I also have the 50mm 1.8 and kit lens with the 600d :).

i just bought a 6D with the 24-105L is as well but i won't sell the 600d as its a great little camera.

ps DP-late night eh? :)
