Now you propose to test a Nikon F-mount (135 format SLR lens) because it is so small (pancake)...

First of all, I never asked that Klaus test the 45mm focal length GN Nikkor.

I simply asked if anyone knew whether or not the $100, 31mm physical length GN version

was as good as the $320 (US dollars) 17mm long Ai-P version that Klaus

did review, on a Nikon camera. It makes sense to me to ask Photozone folks, you are a

pretty sophisticated bunch.



I confess to having an indirect hope to intrigue Klaus as to the topic,

but thank heaven I never proposed any such heresy as a "non-Leica-mount, inexpensive"

lens test for the Nex on Photozone.

But that is exactly what does not make sense. It stops being small on NEX because it

needs a big fat adapter, making its big plus... disappear. And that is a very simple and evident point.

Brightcolours, you're making the same mistake I did at first. EVEN WITH the

18mm-longer-than-Leica-M-mount Nex-to-Nikon adapter,

the Nikon AI-P 45/2.8 and the GN 45/2.8 lenses ($100 on eBay!) are about as small or smaller

than ALL the non-e-mount (and expensive) lenses Photozone has tested on the Nex:



45mm long with adapter, 120g Nikon Ai-P 45mm f/2.8 (PZone reviewed on Nikon camera, several on eBay)

59mm long with adapter, 150g Nikon GN Auto Nikkor 45mm f2.8 (not reviewed, plentiful on eBay)



52mm long with adapter, 147g Voigtländer Heliar 50mm f/3.5 (this and the rest PZone reviewed)

53mm long with adapter, 230g Voigtländer Ultra-Wide Heliar 12mm f/5.6 Aspherical II

61mm long with adapter, 230g Leica Summarit-M 50mm f/2.5

75mm long with adapter, 230g Voigtländer Color Heliar 75mm f/2.5

78mm long with adapter, 240g Zeiss Biogon ZM T* 35mm f/2

78mm long with adapter, 230g Zeiss Planar ZM T* 50mm f/2

100mm long with apater, 260g Voigtländer APO Lanthar 90mm f/3.5

One could argue that the 50mm f3.5 Voigtlander collapses to ~33mm length in the non-operating position,

but the overall point is clear that there is nothing physically disqualifying about the Nikon 45mm f2.8

lens sizes that make them silly to consider for the Nex.

Besides that, the Nikon has been out of production for ages, and is hardly to be found easily in the 2nd hand marker.

So, there are two reasons to wonder why Klaus "should" test it on NEX.... it is NOT compact on NEX, and it is hardly a lens one can purchase.

That's like saying the 50mm f1.8 FD Canon lens is hard to get, because it's not made any more.

The world appears to be awash in 45mm GN Nikkors, take a glance on eBay. There are the multiple $320 Ai-P

versions on there as well.



So I still want to know if any of you brainiacs have had a chance to use the 45mm f2.8 GN nikkor on a digital

camera...
