I just looked through it using the "see inside" feature of amazon.com, and was most favorably impressed! http://www.amazon.com/Digital-photography-science-hardcover-Savazzi/dp/0557911338/ref=sr_1_1?ie=UTF8&s=books&qid=1300318565&sr=1-1 Unfortunately, none of the really useful text is there, but if ...

Is there any chance that this book will become available through Kindle e-books or some other e-book format? I have to admit that I've become somewhat addicted to e-books. I clicked the link on the Amazon.com listing for your book that says "tell the publisher that I'd like to buy this book via Kin...

Some of the relevant answers have already been dealt with in this thread. The main points of using a trinocular head (or a beam splitter/prism/mirror box like Soldevilla's, which is also commonly used in photomicroscopy) are three: 1 - The external eyepiece must be perfectly parfocal with the camera...

angle finder? The big advantage of these optical systems is that they are placed before the camera, and that the eyepiece focuses on an aerial image instead of a ground glass (= much brighter and more detail visible). Precision focusing becomes much easier than on a ground glass screen (as long as ...

Spinning/vibrating DoF adapters
It seems these things are used to artificially decrease the DoF, i.e. produce images equivalent to those made with very fast lenses. They seem to be used mostly for movies, but probably could be used in photography as well. I found the following by accident: http://www.modo35.com/products.html and t...

Nikon infinity CF objectives, instead, seem to work fine (which is not really a surprise). But Nikon CFI60 have a 60mm parfocal distance while Mitutoyo uses 90mm, no? Obviously they can still be mixed provided the person operating the turret remembers which objective is where ... Yes, and it helps ...

As a partial update, while testing a makeshift photo tube, I found that the Zeiss Luminar 63 mm on the FS-60 gives a quite large amount of lateral chromatic aberration in pictures (more than when used without a tube lens). So this is not a workable solution for low magnification. Nikon infinity CF o...

If I remember correctly Pentax made some 2" diameter eyepieces for some of their (tele/spotting) scopes! Not sure how applicable that would be here... 2" eyepieces are in fact available for amateur telescopes, and even a few 2" binocular viewers at high but not impossible prices (see http://www.sie...

Re: Mitutoyo FS-60, first impressions
The binocular head uses eyepieces with 30 mm barrels, by standard 10x with a field stop (i.e. the diameter of the field of view) of 25 mm. The Mitutoyo M Plan Apo objectives are specified for a 30 mm image circle, which is enough to cover an APS-C sensor. I just assume that the tube lens provides t...

Thanks for posting this, Enrico--very interesting to me. I'll be looking forward to hearing more as you go forward. Too bad that zoom isn't 0.5x-1x, instead of 1x-2x. If it were, I'd really be itching for one. The Mitutoyo VM-40 might be interesting. It has a 0.25x-20x tube lens, in total 25x-2,000...

Enrico, Thankyou for the report and details related to this 'fine' scope. Let us know what happens when you introduce light via the illuminator port and if it impacts on image quality. I am planning to build a camera adapter for direct projection, which brings the sensor plane very approximately 10...

Mitutoyo FS-60, first impressions
I took the plunge last week on the big auction site, and this is what the postman dragged in today (not including the objectives, which I already had). It will take time to build a camera adapter and modify the focusing rack for automated stacking, but here are my first impressions. The Mitutoyo FS-...

Thanks for the information. Contrast and color look good. It would be useful to see a 1:1 crop of a portion of the picture, in order to judge the resolution. It is particularly interesting that you did not get any visible vignetting. This is unusual for such a short focal length (although 2x and 5x ...

it could be that the Macro Nikkors act as if their apertures were smaller than their ratings also! As I implied above, I remember seeing somewhere that the 19mm Nikkor was more symmetrical than the Oly. I can't find the reference though, and the memory is fickle. I have a pupil ratio of 0.7 for the...
