Is this the one you are referring too? https://www.ebay.com/itm/Lomo-microscope-1-7x-projection-photo-eyepiece-for-full-frame-cameras-RARE/254601704553?hash=item3b4771b469:g:j80AAOSwOyNew~Hv I have a 3x homal eyepiece in a drawer, but never tried it out. Didn't know they made a 1.67x. Would be inter...

Oh and since it is CF the image is fully corrected by the objective.

You are talking about the first generation CF with plain barrel, as opposed to the CFN (CF new) 60x planapo 0.95 which has a knurled ring. I own the CF PlanApo 60x 0.90 and like it well enough. It's nice and convenient to have a high NA dry objective, but it's never going to produce as nice an image...

This forum is amazing.

I know that Håkan Kvarnström, hkv, has laid his hands on some UPlanXApo's and posted some images on his instagram (@micromundusphotography). Not that his photos were lacking before, but the images from the XApos look outstanding.

At least for me, it would really help to see a wider FOV, I'm not used to seeing only a 400% crop. I've also been quite unimpressed with 100x 1.25 achromats in the past (like my Nikon E plan) so I'm not overly surprised to see CA in the centre, but it's just not clear to me exactly how pronounced it...

Disassembled, cleaned and regreased the focus block of my Vanox AH today. Finally! Didn't take it apart completely, as I didn't want to mess with the gear box, but it seems to be working fine now. The coarse and fine focus shafts were really sticking to each other, but can now move independently. Re...

Yeah, that's the first criticism I've heard of the CFUWs. In what setup do you use them? Since you mention both Zeiss and Leitz, I find it hard to guess what other optics might be in you optical path.

That photograph is great! I'm kind of in a similar boat, although I'm a couple of decades behind, as I'm collecting PlanApo objectives for my 1970's Vanox. But I'm also just beginning to learn to use those objectives to their full potential. Inspiriting post!

My Vanox AH is still not quite operational, but my gear acquisition syndrome is getting worse. Been assembling some more Olympus short-barrel objectives, a 10x PlanApo as mentioned earlier for $70, a 100x Fluor 1.30 for $70, and today I couldn't resist a 100x PlanApo for $175. Costed £602 in 1978, w...

Having small kids is exhausting, so I have almost no time and energy for microscopy. But buying optics makes me happy, so why not look for something new. I am looking for some Olympus short-barrel PlanApo objectives for my Vanox AH described here: https://www.photomacrography.net/forum/viewtopic.php...

Haven't been able to do any further testing lately, but I did pick up a fairly cheap Olympus short-barrel 10x 0.32 PlanApo the other day (will take a while to arrive from China). Will be interesting to compare it with the rest of my objectives, and to see how it works with DIC. I'm starting to gravi...

Pete, I very much appreciate you making these comparisons. It would be good to try at least one identical objective/prism to ascertain if our prisms differ. I mostly use the Nikon CF Fluor objectives, the ones that you can see in the "Nikon CF" catalogue on Charles Krebs' site (not the later Plan Fl...

I did a very very quick test with the Olympus objectives first, the DIC effect was kind of bland. But I was too curious to test the Nikon's so I didn't set it up very carefully. Agree that optimizing it with the Olympus objectives first is the way to go. Klaus Kemp is currently not taking any new or...
