Arthur,
We know by omission that this particular 7x42 does not have phase-coated prisms. If it did, we would have been told so with no uncertain terms as soon as the question came up.

...We have the "pump," with the conspicuous absence of an answer to whether it has phase coating, and no explanation of the warblers in Colorado, in February. I am waiting for the "dump."...
...The great thing about the 7x42 BGATP is that it's so simple - no funky focuser (that may go wrong or requires springs and the like in its mechanism to work properly)...
Hi guys! I was just wondering which 7x42 Dialyt version is the most advanced/modern? The long line of letters after the bin's name confuse|:S| me...
As far as I know, the last BGATP always have the T* P* labeling, but I'm not sure if there is a way apart from perhaps serial number to tell one of those from the mid 1990s from one made later, when they started calling it the "Classic".

So I guess the T stands for LotuTec coating, and the P for phase coating? What does BGA stand for?
No, we are talking about the "Dialyt" or "Classic" model prior to the FL. There was also a 7x45 "NightOwl" or "DesignSelection" model prior to the FL, but there was never a 7x Victory or Victory II model to my recollection.
T* stands for Zeiss' multicoating, P or P* is for phase coating, B is for high-eyepoint (i.e. long eye relief) and GA is for rubber armor. LotuTec came much later, part-way through the production life of the FL line, and is indicated on those bins with a domed-drop icon which looks like a little arc over the format (8x32, 7x42, 10x42 etc) label under the hinge.

How about the contrast and color saturation? How did they compare?

The Zeiss T marking goes back to the early days of WW II and means Transparenzbelag (Transparent Covering) indicating the presence of anti-reflective coated optics. The T* marking goes back to the late 1970's or early 1980's and indicates anti-reflective multi-coated optics. The B means Brille (eyeglasses) i.e. the binocular is suitable for eyeglass wearers and the GA means Gummiarmierung (rubber armoured).
Sorry Brock, only just seen your post.
At the time I was more interested in looking through Dialyt 7x42s for the first time and I didn't A / B them against the SFs, which in any case were being passed around from person to person. So the situation wasn't condusive to detailed comparisons and this wasn't on my mind at the time.

Thanks for replying. I'd be very surprised if the SF didn't have better contrast since that's the primary characteristic I find different in binoculars with newer coatings.
Color saturation is a bit trickier to evaluate because it gets mixed up with color bias. Someone wrote that the Dialyt's image was "warm" vs. the FL's image being "cold," which makes me wonder if Zeiss at one time didn't make AR coatings with a dromedary hump in the middle and steep drop off in the red like the FL, HT and presumably, the SF. Zeiss bins usually have red reflecting off them, perhaps for this reason.
Hello,
We have the "pump," with the conspicuous absence of an answer to whether it has phase coating, and no explanation of the warblers in Colorado, in February. I am waiting for the "dump."
I could join the discussion of this fine glass, but I do not care to play Chariie Brown to his Lucy.
Happy bird watching,
Arthur Pinewood
I paid over $900 for the Zeiss 7x42 Dialyt and I am asking $900 so I am not looking to pump and dump and make a profit. The optics are excellent on it but I just prefer using the SV 8x32 and the 28 oz. of the Zeiss is a little heavier than I prefer. I came to the realization that I really only use my SV 8x32 95% of the time so I decided to get rid of the binoculars I don't use that much. I am actually selling three of them if you look at the items I am selling. I am going down to one binocular because that is the one I use. Many of these other binoculars are excellent but as I have said before " Once you have Alpha it is hard to go Backa". It is kind of stupid to use a $500 binocular when you have a $2400 just sitting there collecting dust. I really don't care what you think of my selling and trading binoculars. It is my business what I do.
Here is the Zeiss lineup for 1984. Note that there is no reference to "Classic," and none were P-coated. The later P and P* models have armored axels with two ribs. I own and use the P-model. Very nice, but not as bright at the current 8x42 SLC-HD, and with slightly smaller AFOV (~60˚). I don't know where the "immersive" quality comes from, but that's a subjective reaction. Mine is a keeper.
