What is the thread size on a Mitutoyo 10x?

I picked up a 10X Mitutoyo Plan Apo Infinity-Corrected Long WD Objective. I bought a 70-200mm f4 lens to mount it to. What is the filter size on the Mitutoyo? I measured it and thought it was a 40.5mm, ordered a step down ring, but it doesn't fit. It is just a little too big, so I figured a 41mm but...

Re: FOR SALE: objectives

Hello Forum, Following changes in set-up, I have a few objectives spare and have put some on eBay. Those potentially of most interest to members of this forum are: Nikon 10x/0.25 Achromatic 160mm Conjugate (Item 171068647569) Nikon CFI Plan Apo 10x/0.45 Infinity (Item 171068658242) JML 20x (Item 17...

I guess a 70-200 lens would work as well? It should work very well, Jody, as long as you keep it close to 200mm. At some point shorter than that, it will almost certainly vignette. However, I suspect--perhaps unfairly--that a good prime might deliver a bit more quality than a good zoom. For someone...

Jody, I've used the Mitutoyo on a 150mm lens (as the "tube lens") and it worked fine. However I was using a an APS-C sized Canon body...sensor size 22.3x14.9mm with a 26.8mm diagonal. Your camera has a an APS-H sized sensor... 28.7x18.7mm with a diagonal of 34mm. This is a close call as far as havi...

re: the mechanical implications, any help you want to provide would be awesome. I've edited my prior post a little bit since having a chance to check the equipment used in some of your recent posts. I'd recalled that you use an MP-E 65mm lens, but not whether you are using a StackShot. The placehol...

Jody, Optically, the basics are that you need a lens to converge the rays from that objective (a converging lens or "tube lens"), and an adapter to fix the objective in front of it. Given your non-macro work, I'll bet you already have some lenses that would work well as converging lenses. Top conte...

Help needed please

I am going to purchase a Mitutoyo M Plan APO 10x/0.28na 33.5mm Working Distance Objective.

I use a Canon 1DMK3 for my camera. Would someone be so kind as to tell me what else I need to purchase to make this work?

Thanks much!

Nicely lit, as always. I put my reading glasses on and see how out of focus this is now! Personally I'd bet on motion-blurred. 1/5 second is about the worst possible shutter speed for picking up camera shock. As Michael mentions, EFSC can solve this problem if the camera has it. I'm not sure this i...

Hi Jody, a beautiful large scale. Nice exposure. The impression of sharpness is not quite as good in my opinion. The sharpness falls off. If you are using the MP-E in the Studio. trying times 5:1 f 3.5 4.5 4:1 f 4.0 4.5 3:1 f 4.5-5.0 2:1 f 5.0-5.6 1:1 f5.0-6.3 I'm using the Mark II, here I put a li...
