Re: Remedy for vibrations
Hello everyone, A very interesting discussion. As Kurt has already mentioned, using very short exposure times can be the solution. My setup is ultralight, yet I can take pictures with high NAs by using 4 YN660 flashes set to 1/128 power and remote triggering, synchronised via RF605C https://www.fac...

Re: Loss of Robert OToole
I hope his website can stay up going forward so that his work can continue to live on. I was reluctant to breach this topic, but now that it's open, I'm wondering if anyone has been in contact with Robert's widow/estate to decide how best to preserve the massive amount of important information cont...

Re: EL Nikkor+Fujifilm GFX
You may have answered this before, but why is it important to cover the full mag range with a single lens? Thanks for the question, Ray. In fact, I think I already answered, but I don't mind answering again; it even helps me remember, because my memory is not good, nor is my attention; I'm diagnose...

Re: Remedy for vibrations
Thanks Ray; It's a great suggestion and more practical to implement. Something like? https://www.gorillatough.com/product/gorilla-double-sided-tape/ Yes, like that, but I've found Gorilla Tape products to be a bit aggressive, and often leave residues. Honestly I've been using tape I picked up from ...

Re: Remedy for vibrations
Hello, unexpectedly I have two identical granite stones -+ A3, which were from a kitchen, about 30mm thick. They are perfectly flat, polished and are very heavy. I remembered that they can provide a good anti-vibration base to place my FLM ballhead. Do you suggest any quick and stable way to attach...

Re: Small backlit stage
Out of interest, will you be using the backlight to help with background removal for coin photography? If so, I have a shared interest in the results you get! Yes, it is for ancient coins. I have a commission from a numismatic archaeologist at a Spanish university to replace/augment their current c...

Re: Exactly how fragile are the mitutoyo 10x 20x etc, or is it an enigma?
Well, I dropped one from waist height onto a bare concrete floor. I think it is de-centered now, but still produces pretty good images overall. The problem I saw with most of the bad lenses was "delam". I don't know if this happens when a lens is allowed to "fall or drop" but it's definitely bad ne...

Re: Exactly how fragile are the mitutoyo 10x 20x etc, or is it an enigma?
I purchased several Mittys, 5x, 10x, 20x, 50x, and every one of them had issues. The only good ones I've purchased were brand new. Not sure how much of a shock is required to damage them though. Some looked fine by inspection, but produced a poor image. Others had delam. I don't think the delam is d...

Re: KEYENCE VH-Z75 what is it?
Looks like a nice microscope Z-stage, and decent XY-stage as well, and you get the objective as well! You'll need to research to find the manual as it is discontinued, but appears to be a 10:1 zoom lens with a high quality objective. Great score for $81+shipping.

Re: Small backlit stage
Thanks Alan! This one looks good at 75mm diameter. I'll see if I can find it from a US seller.

Re: Small backlit stage
Has anyone seen a small backlit stage? Round is preferable, perhaps 100mm diameter. See if this might suit your purposes: https://aliexpress.ru/item/1005006132420668.html?sku_id=12000035904315191&spm=a2g2w.productlist.search_results.3.1a653f428LGVJP Looks very good!

Edited to add: I picked up a 6.5" round LED light from Amazon to try it out.
