Re: Micro-Symmar 3.5x

on the 50mm Micro Symmar I'm still confused about the F2.3 Curves (and missing F2.8 curves) in their data sheet, so I have no idea how to interpret that. very unfortunate though that in real world it doesn't perform as you'd hoped. Hi Chris, The data sheet for the Micro-Symmar has been discussed he...

Re: Newport Damped Optical Posts

Hi Cam,

I have tried a dampened post years ago but I did not like the nylon geared rail strip that was mounted on the post.

Have you seen the dual post Z column that Thorlabs sells? They pop up on Ebay sometimes for tempting prices.

Re: US Buyers Beware of Tariffs on EU Products

Wow this is... ridiculous. (Just remember it's better to not swear! #-o ) Here I am, still annoyed by the 10% we have to pay in Australia. This tariff war was originally waged against China under several debatable arguments that I'm not drunk enough to entertain, now it's extending to Europe and (t...

Re: US Buyers Beware of Tariffs on EU Products

Oh no!!!! Many months ago I bought a $2000 Superachromat lens from a vender in Holland. He sent it a few days ago. Most expensive thing I've bought in a long time. Why did the Korean shipment get charged? Are there more countries besides the ones you listed which have a 25% tariff? Or is itthe plac...

Robert, thanks for the tests and congratulations on a year of life after death. I'm curious why you tested the old Sigma 70mm rather than the new one that did so well in your recent tests? Maybe the new version would have done better. Also, in my tests of the new Sigma, it is sharpest at f/4.0. So ...

I agree that the SM2 solution is very handy ... as long as both lenses fit inside the tube. For the Macro Irises that is likely the case. The adjustment and lens change is not as easy I would like, though. Not true, both lenses do not have to fit inside of the lens tube. I've been using the same Th...
