I love the Lomo 3.7 on FF, but I have had other Lomos that were garbage. In addition, one of my Lomo 3.7 objectives was considerably better than the other. If the price is right, take a shot. If it is very expensive, better to go with known-good objectives with the same parameters.

That objective is for phase contrast and has a dark ring at its back focal plane. It will have poor image quality if used for brightfield microscopy or macro.

Also note that these at short barrel objectives. Most microscope stands can't focus close enough to reach focus. (not a problem for macro).

I bought it from the site and when I arrive I will experience the experience and tell you the result, God willing thank you

I have not tested the Lomo 10/0.3, but do have the 10/0.4. It is quite good in the center, but coverage is poor. I have the Unitron 10/0.3 and it's a decent performer on APS-C, getting a little soft in the corners but OK for some purposes. Hopefully the Lomo 10/0.3 is better than these in the corners. So far I think I've tested >10 Lomo objectives and none have been near the spectacular quality of the 3.7x.

Edited to add:

In my search, I ran across a Lomo 11X/0.4 that I had not seen before. It has an adjustable aperture. Generally the lenses I've seen with adjustable aperture are geared toward photography, so I picked it up. Just had a good feeling about it.

Is there an available reference for the different series of Lomo objectives? Would be nice to know if there are others in the same series as the 3.7X that might be worth looking into.

Edit2: I see there is a 8x/0.2 objective that appears to be from the same series as the 3.7x. Has anyone tested the 8x? There is one online ref from someone using both 3.7x and 8x, with 8x performing miserably, but at the end of the thread it miraculously performs beautifully, with no explanation. Anyway, the 8x seem very cheap on ebay, either because they are not good, or not yet "discovered".

Here is sample from Lomo 8 0.20 160/-

It is only achromatic lens and apparently it needs eyepiece correction.
WD is more than 10mm if I remeber it good.
Sample:

Ray,

Robert has my LOMO 9/0.20 160 plan. I sent it to him, as I heard it is good. LOMO also made an iris version of the same optical design.

LOMO's 8/0.2 160 non plan is a different design. I have not heard people praise it, so I did not send it to Robert.

LOMO also made a plan 3.5/0.1 160. Not sure show good it is.

The 11/0.4 is probably for Fedorov's universal stage and usually used with glass dome. NA 0.4 is not that low to be pushed around beyond design limits, but it may work. Try it and report back , please. Twisted Evil

For sure I will post results when it arrives. I'll also do something with my 10/0.4, and pull out the 9/0.2 as well.

I'm not familiar with the Federov stage or glass dome. Can you elaborate, or point me to a good ref?

Ray,

Regarding that 10/0.4 for universal stage:

https://m.ebay.com/itm/LOMO-Polarizing-objective-for-Fedorov-universal-rotating-stage-11x0-40-iris-LWD/273438591163

https://www.rafcamera.com/lomo-microscope-objective-achromat-11x0-40-polarized

I don't have a good reference for universal stage. I would have to google it myself, so your searching should be as good as mine.

Edit: here is an article, though I don't like how long it is:

I did not like my LOMO 10/0.4 achromat as much as my LOMO apo 10/0.3, under transmitted oblique and darkfield illumination. The 10/0.4 produces visibly more CA and haziness. Oblique and darkfield microscopy are quite demanding on objective quality, but they are very different application than macrophotography through direct projection. So YMMV.

However, the LOMO Phase Lumin Fluor objective FL 10x 0.30 is close to Olympus UPlanFL N 10X / 0.30na Objective

I received the Lomo 11/0.4 objective today. Unfortunately, it is very disappointing. Seems my "gut feeling" was way off. Wide open, the contrast is horrendous. I think this is due to flare, but I can't seem to control it. The contrast problem improves stopped down 3-4 stops, but by then the resolution is poor. Plus, it has a lot of field curvature, and does not cover APS-C. What a boondoggle!
