I tried using this lens for birding but was having quite a hard time focusing this monster on fast moving birds.

Tonight I decided to "shoot the moon" ... Very Happy

I added an old Kristar doubler to the lens.

Pretty decent I didn't see better moon shoots with any 400mm lens.

Hey guys, thanks for taking a look.

I was surprised that the lens performed halfway decent on these images. I was truly thinking I would get very soft images especially with the old Kristar doubler attached to the lens.

All in all, the lens performed OK. I think I will be doing more shots like this in the near future.

I also have a telescope on the way. This could be quite fun... Very Happy

It may be interesting to have a picture of your lens.

I've read somewhere that Optomax is actually a rather sharp el cheapo lens. One of the best at that price point. Anyway, that's some surprisingly good output indeed!

It looks like Soligor 400mm f6.3 :

Looks like a Tamron make.

Im not sure if mine is a Tamron. The grip is all wrong when compared to my 200mm and 300mm Tammy's.

Not Tamron, Tokina.

It is the same as the T4 version sold as Soligor and Vivitar.

Which lens is the Tokina, mine or the Soligor above?

Both I think.

Well, I made a mistake in identifying my 200 and 300 as Tamron made. They are Tokina, my mistake. Embarassed

The 400mm dosent look like either of my tele's, Im not so sure it is a Tokina lens, but I could be wrong.

Really nice pictures, almost seems to be better than my Pentacon 500mm.

The mount end is different because the Soligors (and the equivalent Vivitars) are equipped with the T4 interchangable mount. Thats why they lack the M/A ring for one thing, that feature, if necessary, is built into the T4 adapter itself.

But Tokina also made this model for many other vendors, in fixed mounts, hence the M/A ring, and the wide variety of other cosmetic variants, like the different covering or knurling of rings. These cosmetic items were easy to vary while the underlying structure remained the same.

That structure is visibly similar in these, the location and spacing of the various features is identical and distinctive, though the most telling feature of this particular lens is actually the enormous built-in hood.
