Re: Nikon Eclipse DIC PF and PA objective prism sliders

Thank you for the insights. Will be happy with the sliders that have as notice even the PF sliders are now much more expensive than when I bought them in 2019.

Hi In case of interest, the November 2018 issue of Micscape e-zine has a review of Julian Cremona's latest book published in September as below.

Paper comparing Olympus TG-4 camera and Canon macro lenses

Hi Recently treated myself to a secondhand Olympus TG-5 in particular to explore its built in Microscope Mode with internal and external focus stacking options. The public domain paper below by Jan Mertens et al is an interesting comparison of the TG-4 (same features) with the Canon 60mm and MP-E ma...

Interesting :). Any reason why you couldn't drill a hole in a cheaper unit? Hi Chris The plates as far as can gather from online resources are an array of semiconductors filling the whole plate area so would compromise the unit if drilled a hole. These examples also have very tough ceramic plate to...

Maybe I'm easily pleased, but watching something akin to snowflakes growing (actually dew condensing and freezing) in real time in a warm room is rather fun and fascinating. Zeiss 2.5X objective, side gooseneck lighting. This uses the Peltier plate at 10V 2A remarked on previously. Although as it's ...

Peltier plate TES1-11930 with hole for cold stage

Hi Peltier plates with holes seem much less common than the solid plates but the TES1-11930 3 x 3 cm with 5 mm hole 14V / 3A 24W works well for transmitted studies from early trials. (Plate mis-labelled as TES1-11903 by some eBay and Alibaba sellers.) Easier to work with than the cheap TEC1-12706 so...

Hi Pau

Ah. many thanks, you've just unclouded my flawed thinking.

Been using a mirrorless EFCS more than the Canon and got confused how EFCS worked on the latter. Setting a long exposure does show the EFC working during exposure.

Doh.

Hi Rik

Thanks for the quick response and good thought. I haven't used the flash but tried opening and shutting to check OK and still gives no EFCS.

Lost EFCS on Canon 600D?

Hi At the risk of asking a dumb question I’m a bit baffled by my Canon 600D. In Live View mode by default doesn’t it always have EFCS on with no option to disable. So mirror stays up all the time and when fire shutter it exposes with electronic first curtain, finishes with mechanical, and mirror sta...

Hi John

It was just basic near IR with an optical microscope using a security monochrome camera as the sensor. Only a VGA sensor when taken so had to stitch to get a passable image.
