Hi !

I just made a quick test of the two 70-300 VR f/4.5-5.6 lens on my Nikon V1 ! (of course, I used the FT-1 adapter for the 70-300 FX).

I set the V1 to Aperture Priority (wide open) and ISO 100 ! The others settings are 100 % equals for the shots with both lens. I shot in RAW and compared the images 2 by 2 in FastStone, then saved a screen-copy in *.JPG, so there have been no conversion/post-process at all !

LEFT: 70-300 CX - RIGHT: 70-300 FX

FULL FRAME at 70mm.

To my eyes, it looks like the new Nikkor 1 VR 70-300 f/4.5-5.6 is slightly sharper (and colorful) than the FX one !

Comments ?

Ohhhh... and another thing: the AF speed of the CX lens is MUUUCH FASTER than the FX one ! It lockes on the subject immediately !

Oh, you just rigged this test. You drank lots of coffee so the caffeine was buzzing when you took the 70-300 VR shots. You shot the 70-300CX locked down on a tripod, the 70-300VR you were waving around like a flag. What kind of objective test do you think this was?

Oh, wait, it perfectly matches my own experience and I don't drink coffee ... oops, I guess you DID get it right after all! :);)

J-P, the one issue I do have with the 70-300 CX, and this is really more the V3 than the lens, is that you really need to fill the focus reticle for quick and accurate lock-on. Not surprising, I guess, but I do find it more "finicky" in this regard than the D810 and D7100. But fill that focus point up, and BANG, you got it!

Nice example of the differences, well done.

Oooopps ! Indeed, I totally goofed !

The 200 and 500 % images above are in fact crops of the 70mm. shots !

Awfully sorry !

NOW.... here's the 200 and 500 % crops of the 300mm shots wide open !

Nikon has hit a homerun with the 1Nikkor 70-300.
Where else can you get 800mm f/5.6 performance (in daylight conditions) for only $1000?
Achieving the same thing on my D4 would cost $18,000 for the FX 800mm f/5.6 lens.

...and just think of the PORTABILITY of such a combo ! (I mean the D4 + 800mm f/5.6) ...and you MUST add a tripod, which is more weight to carry !

I am trying hard to use the V1 + 70-300 CX (at 300mm.) HANDHELD :) ! ...of course, tis needs quite some light, but it should work allright !

Of course, if someone next to you shoots the same subject, with a D800/D4/D810, when you check the image, there's a "slight" IQ difference, but.......

:D
