NIKON NIKKOR 105MM-F/4 LENS FOR BELLOWS FOCUSING ATTACHMENT

paulr

Do any members have any experience of this lens when used with a PB-6 and a PB6E Bellows

It is designed to be used only with bellows. It's a tad expensive and rare so help would be appreciated

Godless

Why bother with one of those? Get a 105mm Micro-Nikkor f/4 AIS and a cheap bellows unit instead..

paulr

Thanks for the advice Godless,
But normal Macro lenses have limited use when used with extended bellows
when focal lengths change. It as to be a specialist lens to cover the reach , up to 483 mm when fully opened
Even reversed lenses cannot cope. Sometimes enlargement lens are used due to the front flatness but it's a trial and error method.

This particular lens is designed to cope with this problem, focus is done by moving the bellows, It is not a lens made for camera use.

Paul, what is the primary difference between the optics of this lens and something like a Nikon 80mm f/5.6N EL-Nikkor? Is this 105 you are mentioning a fully coated lens with all the f/stops? That is of course the issue with the enlarging lenses...not a lot of control.

paul, thanks to your input I checked a dealer's website. Currently a lot of Rodenstock large format lenses are on Sale at ridiculous prices, between 20 and 40 % of new price. I'm very tempted.

I own as well enlarging lenses from Schneider Kreuznach which I used to reprograph my slide collection. Problem was, the f-stops were illuminated by the enlarger lamp, I first had to close the light channel with black tape. otherwise it went well. The Schneider Componon S have steps for f-stops which can be switched off.

Even Dear Old Ken R. as something to say about this Lens





:-h

Msmoto

Thanks, paulr....

I am still thinking an El-Nikkor might be better when one is at magnifications of larger than 1:1...like 1:5 or more. The El-Nikkor would be in its working range of about 1:3 to 1:20.

But, we will have to see. I might get hooked into this macro stuff...

Macro Photography keeps you occupied when the weather is bad, and in the Uk we get plenty of that. \:D/

After spending hours trolling through the Internet I found this Nikon 105 F4 bellows Lens in

MILWAUKEE, USA in near new condition

Now its mine on route!

Msmoto

Mmmm...must be the one I was outbid on yesterday... )

paulr

Msmoto I would never bid against a friend LOL

While I am waiting for delivery I am still playing with toys, Here is a photo I did today It was a little plant. It was not until I saw it under the macro lens I noticed the plant had company, I could not see it with the Naked eye. Scary

I use a 50 f/1.8 on a reversing ring and bellows. The resolution I get is pretty close to being at the limit of optical resolution.

Yes you can get higher magnifications, but you can't resolve better than a wavelength or so.

The big problem that hits with that setup though is the depth of field goes really thin and you need to stack shots to get useful results. The DOF goes to fractions of a mm.

What I really want to do is to mount the camera and bellows securely to my CNC mill so that I can use that to move the camera in and out and take a set of stacked shots automatically.

paulr

Myrddin, Stacking at high magnification is the only way forward, as you say, DOF is virtually zero, Gognisys are the only manufacture as far as I know who make a pre set auto system with extremely small movement.
Its early days and I am testing al kinds of configurations with different lenses and bellows attachments.

I am near to the edge of microphotography, but at this stage simple macro images will have to do. :-?
