I have used Olympus splan objectives and they do work. However they also tend to be higher priced than the Nikons. I am always looking for the best value for my money. Although if a good Splan objective pops up I will look at it, especially given the Splans have a wider FOV.

So I have looked at the Nikon 20X/0.75 Fluor vs the Leitz Pl Fluotar 25X/0.60 objective. The Nikon has about a 25% larger FOV which corresponds well to the lower magnification. Resolution of the Nikon objective was slightly better than the Leitz although very close. I stared at multiple Diatoms for about 30 minutes. The image was brighter when using the Nikon, no doubt in part due to the lower magnification.

All in all the Nikon performed admirably with the Leitz eyepieces. I still have yet to look at the Leitz 25X Oil immersion objective. I expect to do that tonight perhaps.

As mentioned my purpose was to determine if I could use Nikon objectives as less expensive alternatives to Leitz objectives. I have previously looked at Olympus objectives and found them to perform quite well also. However, Olympus objectives tend to be a bit pricey also.

This particular Nikon Fluor objective only cost $90, quite a bargain actually.

When rotating the turret to the Nikon Objective it did require some minor adjustments in focusing so it was not parfocal with my other Leitz objectives, but the difference was not significant and did not present any potential slide contact. Given the working distance of both objectives I would not have expected that anyway.

More to come.

They can be pretty good value for sure, I got my set of 10x 0.50, 20x 0.75 and 40x 0.85 Nikon Fluor's for $250 (originally $300, but the seller knocked off $50 because the correction collar on the 40x was stuck, which I have since fixed). I also have the 40x 1.30 oil, but paid a bit more for it. All give a very very clean and super bright image. The 40x 1.30 is stellar. They aren't designated as Plan, but give a perfectly fine image nearly all the way to the edge of the field when using CFW 10x eyepieces. Quite underrated, me thinks.

Just keeping this thread open. I have been traveling but hope to post some additional comments regarding the Leitz oil immersion objective.
