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...

Guilty as charged

Will re-up now.

https://www.photomacrography.net/forum/download/file.php?mode=view&id=931 These are highlights from the Minolta DiMAGE Scan Dual IV AF3200 lens I just posted on my site. Some of the results were a nice surprise. I also ran about 10 other lenses at the same time, also at 1.4x, that I will share late...

My project to-do list has been taking all my time lately but I am slowly making progress! First up: AF-3200-layers-blank.jpg But the test is not public yet, anyone have some free time to help me with errors, typos etc? https://www.closeuphotography.com/minolta-scan-dual-iv-scanner-lens-test PM me fo...

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.
Best,

For lenses (and other photographic equipment), the place of manufacture is restricted to Germany. See https://captureintegration.com/tariffs-that-will-affect-you-the-photographer/ Best wishes on the safe and trouble-free arrival of your Superachromat. Best regards, David Hi David, It is Germany, bu...

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...

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...

Quick heads up to anyone living in the US and thinking about ordering something from overseas. Earlier this month a South Korean seller sent me an inspec.x L lens for this post: https://www.photomacrography.net/forum/viewtopic.php?f=25&t=41911 A couple of weeks later I got a bill in the mail for Fed...

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 ...

On the 1 year anniversary of my Cardiac Arrest and heart attack, I'm glad to be able to share the inspec.x L 5.6/105 lens test results. The full test on my site: https://www.closeuphotography.com/inspec-x-l-lens The inspec.x L lens was tested at 0.3x on extension and 3x stacked. The results were ver...

I would like to buy the Nikon MM 10x Measuring Microscope objective.If you can send payment details including postage to the UK.

PM sent, thanks.

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...
