I would like to indentify generations and age of Zeiss Diascope 85 T*FL.
What colours was DIASCOPE 85 T*FL models just before Harpia's (I think Black, right)?)
Are the green versions older or not (I would says yes, right?).
Thanks for confirmation
Never mind the colour, look at the focusing knobs.
The oldest models had two focusing knobs, one for fast focus and one for fine (slow) focus.
Later models had only one focus knob but which combined both fast and slow focus depending how fast/forcefully you rotated the knob.
To my knowledge as Lee says the Diascope was updated from the green and silver 20x60 versions in 2013 to the black 20x75 single dual focuser. I have a 2015 85T*FL model which i have found excellent. The image at 20 through to 75 is natural and pin sharp. The FOV is also superb and because the eyepiece is big it feels very comfortable to use and has good eye relief. It is built like a battleship....well crafted and handles well . It is extremely smooth and fast to focus. I have the latest version stay on case....also very well made but the whole package needs a good tripod as its quite heavy.....about 5.5 lb with eyepiece, case and arca Swiss qr plate. I use a Benro CF tripod with S6 fluid head. You'll need a good fluid head to stabilise the scope. It's great for phonescoping also. I use a Samsung S9+....and mount it on a PhoneSkope case and eyepiece attachment with blue tooth shutter control.
You might guess from this that I'm a big fan of Zeiss.....
Here's a picture I took yesterday....I think the photos compete with some of the pro cameras and big lenses ( only my opinion).

Very Nice Scope :t: Also your back yard/lawn and garden looks pretty nice also. That’s one thing I do not miss doing anymore ... getting that dam lawn mower, along with all those garden tools out of the garage :C:C:C. Thanks for sharing
Thanks for your kind comments.
Have you British origins?
We nearly moved to Florida in the early nineties.....but didn't! What a wonderful place. I know Jacksonville is to the North but I've never been there.....only went to Orlando, Miami, Sarasota etc:t:
I thought that the 25-75 zoom was not the best for the oldest generations
The 20-75x (it's a 3.75x zoom!) works well on the older scope versions - just don't lock - the last version has a ep locking system that didn't existed before. This zoom isn't the best for eye-glass users since the eye-relief can be a limiting factor for some - it's for me - the reason why I don't have one...
Zeiss Diascopes are known by high sampling variability and not so good finishing quality - test always before purchasing!
Have you had a bad experience with Diascopes? When I researched them before buying there were many excellent reviews and articles which along with the Zeiss brand reputation, convinced me to buy. Allbinos and respected birders/naturalists gave it superb reviews and in its day (only a few years ago) it was regarded as one of the best scopes.
I'd be surprised if Zeiss, with their quality control, guarantees and high craftsmanship would allow sample variation and questionable quality in such a flagship product.
I've tried Kowa, Nikon, Hawke and Opticron scopes and with the 20x75 zoom I found the 85T*FL to live up to its name as an impressive bit of kit.
Mine is an old Diascope 65, 15-45x, in silver, with two focusing knobs and looks like the pic below.
I still have one of these, although I now use a lighter scope 50 mm scope for general use and a heavier 82 mm for when I want more light/power but if I had to go to back to one scope I'd use the Zeiss. It had over twelve years of use and I described it many times as the best bit of optical gear I'd ever bought. The zoom eye-piece had a huge field of view for the time.
