Re: Olympus BH2 LED Lighting

Viktor, I use a Yongnuo YN560EX (GN 58) with a cube beamsplitter in this setup: http://www.photomacrography.net/forum/viewtopic.php?p=224611#p224611 I don't recall having used more than 1/8 power setting for 40X 0.70 DIC, although our systems are very different Well, that suggests that there is roo...

Re: Olympus BH2 LED Lighting

This is such a great post! I actually have a question about flash illumination that I've been meaning to ask. I have recently put together a combined flash/led illuminator for my Vanox AH, based on the same principle as Charles Krebs' setup - flash tube removed from the flash and placed at the locat...

Re: Unidentified OLYMPUS objective

It's a centrering objective, used to center the image of the lamp filament in epi fluorescence.

Re: This Just Seems Strange

Between the "best offer" option, low postage costs, no need for a credit card, no new account, and no restocking fees, it might even be easier to buy from them rather than from Thorlabs directly. I think this is spot on. I've never bought anything directly from Thorlabs so I don't really know how i...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

That Nikon 60x 0.95 is really impressive, Soki. I need to test my 60x 0.90 more carefully to see what I can get it can do. I never really expected it to produce such good images; I simply assumed that it would always be better to use immersion objectives for those kinds of subjects. I tried to take ...

Were you thinking about these measurements? It's the only quantitative measurements I've been able to find. Would love to see more data like it.

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Interesting to hear about the Olympus/Lomo match! I've never seen any data on the LCA of Olympus SB objectives. Where did you find this information? Do you know how similar the SB and LB objectives are to each other? They say that FK and NFK eyepieces aren't interchangeable. But I've briefly tried ...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Now thats comprehensible. There seem to be some Olympus Vanox with DIC for sale out there, because they were probably used often with DIC. This DIC looks really awesome, especially in combination with SPlanapos. Congrats for the great deals! The prices for these lenses are really low. The standard ...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Oddly enough, I am moving to the Olympus short-barrel PlanApos. I've come the opposite way :), well, almost. Old JIS Olympus Plan objectives was the first "imported" objectives for me (eastern bloc LOMO/Zeiss/PZO/Meopta etc. doesn't count), and I did like them. Some photos using LOMO MFN-11 trinocu...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Yup, Alan Wood's site is such a treasure trove. The most complete catalogue of SB objectives is this one:

They are said to be corrected up to a field number of 29mm! Would be cool to find a UW head for my Vanox...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Hey guys, It seems like I'm moving away from Nikon CF after equipping my Olympus Vanox with PlanApos, but if I had continued to invest in Nikon I would definitely had bought a 60x 1.40 planapo. My impression is that there has been more of those on the market over the last year or so, for quite dece...

Re: Nikon CFN Fluor / Planapo 100 160/0.17

I agree with PeteM. While I haven't tried the 100x's, I can't imagine the difference being very noticable. All the Nikon CF (non-plan) Fluors I own are really excellent (10x 0.50, 20x 0.75, 40x 0.85, 40x 1.30). The 40x 0.85 is perhaps the weakest link, as it does seem to be a slight step behind the ...

Re: MAG.X 8X / 0.32 LD PLAN APOCHROMATIC OBJECTIVE

Haven't read your test in detail yet, but in the last picture you posted here I definitely prefer the right-hand image. Sharper, as you say. But I'm also seeing quite a bit of purple fringing on the long bright lines in the section above the numbering on the left-hand image? These lines are very cle...
