This is yet another early 1960's novelty lens from Tamron. The "Nestar" is a collapsing or nesting lens, that can be shortened by unscrewing the back half and pushing it into the front half.

This does reduce the length of the thing by almost 1/2, which helps fit the thing into a small camera bag, or an overcoat pocket perhaps. There have been several lens makers (Komura and Nikon, among others) that have attempted to make long lenses more manageable, but the usual solution is just to unscrew them into several pieces. This one keeps the whole thing as one piece. A neat trick. Also neat is that the thing includes a tripod mount placed flush on the barrel, the first I have seen.
Otherwise its a very conventional preset T-mount telephoto of the period, probably the same as the other, fixed, Tamron 400/6.9. The fit and finish is perhaps not as good as the earliest Tamrons, the engraving is very shallow and the finish is semi-flat, not deep gloss enamel. The finish looks much like that of the historic 95-205 zoom. I think this was meant to be sold cheaply.
Tamron made quite a few of these types of gadget for the consumer market - the first consumer zoom, cheap long telephotos, duo-lenses with matched multipliers, extra-long zooms, etc. as this sort of novelty appealed to the amateur.
Optically, this is a perfectly usable lens with more than enough sharpness and contrast to give good results for anyone who can master a manual 400mm. Even if it did make consumer novelties, Tamrons lenses were still respectable.
It does have an annoying tendency to unscrew while focusing, as mine has a rather stiff helical. Minimum focus is typical of its type and period at 30ft/9m, which is a bit long.

It looks like you guys still have nice weather down there.
Here in northern Washington it's violently stormy.

The Cormorant shot is gorgeous, such detail for a black feathered bird. This 400mm is very decent lens.

I've not been out with my copy yet (which I've somehow managed to seize the collapsing threads on, doh!), but my quick and dirty tests out of the window show this to be my best 400mm prime, better than my old Hanimex Tokina made 400/5.6, the newer Soligor Tokina made 400/6.3 (also sold as a T4) and the newer Soligor Kino made 400/6.3. The minimum focusing distance, while stated at 9m, is actually slightly less too! The best feature those is the almost complete lack of CA

Thanks Marcus, very interesting.
My own tests with it to date confirm that the extension screw could REALLY do with some sort of locking pin. The focus on my copy isn't particularly stiff but the nesting still comes loose in operation (the T2 ring wants some thread lock too)
It does seem to perform reasonably, beating my other 400mm lenses (it's not a common focal length in my hoard), with no purple fringing in the shots where I nailed focus on APSC.
I've not yet tried it one my A7ii, which will test FF performance & IR handling. |
