Re: 24MP "only" FF camera with Pixel-Shift

Macrero, even I think that my description of the modification process is confusing. I swear it seemed clear when I wrote it. If you have trouble, when you get the parts I can open my adapter and post a photo. The S1's 96MP pixel-shifted files are more than I need resolution wise. But I promise you t...

Re: 24MP "only" FF camera with Pixel-Shift

Btw, I recall reading you had a problem with triggering the camera with the controller. Can't find the thread now. How did you solve it? I got a simpler Lumix FZ300 remote control and cannibalized that to attach to the WeMacro (Stackshot would be the same with different end socket). I had to modify...

Re: 24MP "only" FF camera with Pixel-Shift

I have the S1R and though I don't use the pixel shift very often, I really like to have it there when I want it. My computer is old but manages the stacks, though slowly.

Re: Blog on UV and other aspects of microscopy and imaging

This is a very nice resource; I learned a lot from your articles on silica slides and on Luminars for UV!

Re: Packing expensive objective lenses for shipping.

But seriously, you're buying 1k objectives from god knows who??
Where else can we get them? Most of these are not current models, and are not available anywhere. And there is feedback, so we do know something about the seller.

Re: Packing expensive objective lenses for shipping.

That's terrible! But I have seen even worse packing. One seller on ebay sent me a beautiful Zeiss photolithography lens that weighed ten pounds or so (perhaps a hundred thousand dollar lens when new), with no lenscaps, in an unpadded cardboard box. Not even bubble wrap. And nothing to anchor the len...

Taht's what I do now, with a geared cine follow-focus device.

Re: Packing expensive objective lenses for shipping.

I detest B&H Photo and Vidoe packing. They used to be good but over the last few years they often include only ONE (often deflated) little airbag, on one side of a six-sided box, and no styrofoam or other padding, even when the lens inside costs thousands of dollars. They should be sued for negligen...

Re: Delphinium

Thanks for the information. I have been trying to build a rear standard stepper system with a full size view camera but without much success.

Re: Detalles moneda de 2 céntimos de euro, luz coaxial. 100x (apilado).

Thanks for your answer Adomacro. My question was more specific. What 100x objective was it? Finite or infinite? And what size is the sensor: APS, FF, MFT? Also, why the dichroic mirror? What color does it reflect? Are you sure the mirror was dichroic? The diversity of colors in the final image sugge...

Re: Delphinium

Very nice, and completely free of stacking artifacts. Do you think moving the rear standard helps with that?

Re: A question for fluorescence microscopists

Excellent, this is great information, thanks! I had seen blanket recommendations that a normal thin glass coverslip does not block UV light, but your thoroughness reveals that this (and fluorescence too) changes dramatically with just a small change in excitation wavelength. Very nice thougthtful de...
