I'm not much of a collector of gear...at least not intentionally....but, well, this lens had been on Craigslist for a few weeks and I finally caved...
It has the same optical formula and coating as the AIS...apparently the differently configured aperture leaves may affect the bokeh differently than the AIS and I'll be testing that....
...what I've always wanted to do was to compare this version's long-throw focusing to the shorter throw of the AIS version I have...to see which version is easier for me to lock focus.

It's very clean, inside and out....except for the "stardust" you can see here.
I've been told it's condensation...looks like it...but it appears to be permanent...hopefully it has little affect....

Can anyone explain how to remove the front element to get behind it and clean off the droplets....?



...one reason to "bag" this lens is that I have two of the others in this "family"....the 200 being the last lens I own from my 1960s PJ days...
