Extension Tube for Nikon 105mm F/4 AiS

[gad-westy]

Hi all,

Sometime ago I grabbed a bargain Nikon 105mm AiS F/4 micro lens. In common with seemingly most Nikon Micro lenses of the period it has a maximum reproduction ratio of 1:2 rather than 1:1. Ideally I'd like the option of 1:1 on occasion.

I know at the time Nikon made a PN-11 Extension tube which took magnification back to 1:1. It looks a lovely bit of kit but would cost me more than I paid for the lens itself so unless I stumble on a bargain, I think I'll rule that one out.

So, just wondering what I should be looking for, ideally in the way of an ebay bargain. If it's tube's I'd ideally like to keep being able to meter. I'm also totally unclear as to how the length of tube affect magnification. I also wondered about a Raynox. I've had one before but never used one with a macro lens.

Overwhelmed!

Seriously though, surely somebody else has messed around with these old Nikon micro lenses?

Have a look here for info about your lens,

and look here for info about the various Nikon tubes,

Get 50mm Ai extension tube set, for 1:1.

Bayonet type is best for quality, as the threaded type feel cheap and are more awkward to exchange the varying lengths ( you normally get 3 tubes in a set ).

Also with threaded tubes, as you change the 3 tubes around for different effects, fine alloy dust eventually starts to emerge. Its very miniscule, but not something you want

Just another thought...you could use a 2x TC, although it acts differently to a tubeset, the end result is the same.

A 2x TC will magnify the image, so you wont have to move closer like you do with an extension tube, which moves the sensor away from the macro lens, which mean you have to move close, and therefore the image size increases

Cheers gents. Some great info here.

Funnily enough I did give it a whirl with a 2x converter that I used to own and the results were good. The reason I've shied away from that is partly because they're expensive but also, they will always have some sort of detrimental affect on IQ where as tubes avoid this.

Cheers once again. Off to look at tube options.
