10,5 mm Nikon rangefinder lens

[digitalintrigue]

I find the heft of the 10.5cm makes it well-balanced, and relatively easy to hand-hold without motion. Not sure how much bigger it would have been to reach f/2.0; besides, that's what the 8.5cm/2.0 is for.

I agree with you;the 85mm/2 is not to large or heavy but the 105mm/2.5 is large enough. This makes me suspect that the 105/2 for RFF would be even larger and heavier. The SLR 105/2 is large and heavy, isn't it.

Actually, the 105/2 AF lens. The 105/1.8 was the manual focus lens:

"The 105mm f/1.8 has a 9-bladed diaphragm, has a built-in telescoping hood, and takes 62mm filters.

It has five elements in five groups.

Close focus is 3 feet or 1m.

It is 3.1" (78mm) around by 3.5" (88mm) long and weighs 20 oz (580g)."


The weight is 580g,and this is quite a lot. If a RF version of this lens wieghs this much, it would be too heavy for a RF lens.

This page indicates 525g. I doubt the 105/1.8 has any brass content like the 1950s lenses. Also, note the weight reduction progression in the 135/3.5.

The Canon SLR 100/2 takes a 58mm filter and weighs 16 ounces/460g -- that's with a modern lens. If you used the brass and chrome of 1950s Nikkor construction quality, it would have jumped a lot higher. The RF Nikkor 105/2.5 weighs about 500g.

Vince,

Usually, AF lenses are lighter than their manual focus counterparts. Maybe that's why the 105/2 has as weight 500 grams.

Raid,
the 105 f2.5 in RF mount weighs 525 grams
the 105 f2.5 in SLR mount weighs 435 grams
the 105 f1.8 Ais weighs 580 grams
I have the 105 f2.0 Defocus control lens, it's the heaviest @ 640 grams

I have the 105 f/2.5 in Contax mount that I use with my IIa. Getting the Nikon BL finder was a pain and cost me $300 when I found one. Great lens.

I also have the black 85mm f/2 in Nikon mount that I use with my SP. Great lens.

I use them both. The 85 is easier to use with the SP viewfinder

there is a very clean looking 105 in LTM on ebay right now, ending in 1 hour, price is climbing... kind of dramatic (no connection to seller...)
