Re: MEJIRO GENOSSEN FL0530 4.0/110 FLOAT LENS TEST IS FINALLY ONLINE

For those interested, Chendata recently listed a FL0530: https://www.ebay.com/itm/116040198607?hash=item1b0488e9cf:g:Pb0AAOSwZoRkMCXu Admittedly, I had to stop myself from purchasing the lens! He also has a Schneider Xenon-Diamond 2.3/116 3.5X listed, which is very intriguing.. https://www.ebay.com/...

FS: Color Gauge Nano - Xrite configuration

Color Gauge Nanon in Xrite Color Checker Configuration for sale. Perfect for color calibration in macro work. I purchased this a few years ago from Digital Transitions and simply never used it since my extreme macro work slowed down: https://heritage-digitaltransitions.com/product/colorgauge-nano-ta...

Trisetella hoeijeri

It's been quite some time since I've posted here. My little Trisetella hoeijeri is in bloom and it's too beautiful not to share. Images taken on Fuji GFX50S using an Arca-Swiss Universalis II and Schneider-Kreuznach Apo Digitar Macro 5.6/120 at ~0.5x. I haphazardly moved the back standard instead of...

Ushio line scan lens (3.5x) on Ebay

An interesting lens popped up on Ebay recently. It's an Ushio line scan lens purported to be designed for 3.5x. https://www.ebay.com/itm/1PC-USHIO-UPL-64-TAB-exposure-machine-line-scan-UV-macro-lens-3-5-times-M72-port/303444994342?hash=item46a6bb2926:g:pswAAOSwuCBeHYMM I tried to find information on...

Thanks for your work, as usual, Robert! I own the APO digitar 120 and absolutely love it. Your stacked results continually tempt me to try purchasing a Componon 35 or 28 and giving it a go with the Fuji GFX sensor. I have only found these for sale on Edmund Optics new for just shy of $1000. Were you...

Thank you for sharing that slide, Robert. That is definitely something to take into consideration. Also, the working distance of 31mm may bit a bit limiting but to be expected with a focal length of 50mm. If I were adept at testing I'd ask the dealer to send both the micro-symmar and the xenon-sapph...

Robert,

I may also be confused, but I do think the MTF is for 3.5x. The way I interpret it is 1/magnification=0.29. This works out since 1/3.5 =.29 , though I could be interpreting this all wrong!
Now, why they have MTFs for f’=2.3 and 2.5 when the lens is listed at 2.8 is beyond me!

Robert, your results are quite impressive! I do wonder what type of image circle your lenses can cover. What intrigued me so much about the micro-symmar is it’s ability to cover a large image circle (though I do agree, the dataSheet seems a bit off). Chris, here are the quotes: Xenon-Sapphire 4.5/95...

Found a dealer for the SK Micro-Symmar 2.8/50mm !

The Schneider-Kreuznach Micro-Symmar 2.8/50mm is no longer listed on the SK website and as far as I knew the lens was discontinued. I contacted a dealer of line scan lenses about pricing for the Xenon-Sapphire line and to my surprise they told me that they can in fact still get the Micro-Symmar! The...

SK contacted me saying that the 1.5/82 is discontinued. What a shame. Maybe it will emerge on the used market at some point. Excuse my ignorance Ray, but what are "TB" and "AE"?

Schneider Xenon-Diamond

I've been thinking more about higher magnification lenses for large sensors and my search always brings me back to the Schneider Xenon-Diamonds. Initially I was looking at the Xenon-Diamond 2.2/117mm which is optimized for 3.5x with an image circle of 62.5 and Schneider notes that it can even cover ...
