My favorite 7x42 is the Zeiss BGATP/ClassiC. It has excellent handling properties, rapid focus, 450 ft FOV, easy eye positioning, reasonable weight, and less off-axis astigmatism than the FL. If I could overlook the astigmatism, and wanted even better waterproofing or consistent focus performance at extreme (high or low) temperatures, I'd get the FL. The FL is also an excellent choice for all-purpose use as it focuses to a class-leading 6 ft. Swarovski and Leica alternatives, by comparison, suffer some combination of failings such as high weight, focus that doesn't work as well with gloves, 420 ft FOV, poor close focus, much more CA (esp. off-axis), and not so generous eye-relief for glasses.
If I already had the P model Dialyt AND the FL, I wouldn't bother with trying to acquire another 7x42, unless I was a massive Swarovski fan. That said, comments relating to the 7x42 SLC appear very positive, except for its weight (I was going to suggest you correspond with dwatsonbirder as I recalled this was his work horse for many years, but see he's already replied). Trying before buying would be (as always with these things) the best policy, but they're not too common, so you might have to wait a while to do so - though cooling one's ardour might not be a bad thing...
I have the 7x42 Dialyt and, though it still delivers a great image, the bridge setup is a potential weak point of this design - mine was a little wonky when it came to me (resolved after service by ECBR, thank you Mr Hawkins) and other owners have also noted instances where this has happened to them - and although a lot of 7x42 Dialyt owners use them much harder than I do mine, if truly hard usage a la dwatsonbirder is in store for your 7x42, I can see why something like the SLC or the Leica BA/BN might be preferred. A pity Zeiss never updated the old Hensoldt design - those excellent optics in a chassis similar to the 8x30 and 10x40 Dialyts would have been a superb package. They could then also have made a 10x42, with Abbe-Koening prisms...
Swarovski still makes the 7x42 Habicht, both in black and green armored.
The FOV is smaller than some others, but the view is special and very good.
I have a 7x42 Leica BR (2004)that was repaired and optically upgraded by Leica a few years ago. I also have a 7X42 SLC that I purchased second hand after it was refurbished and upgraded with a new serial number by Swarovski.
The Leica is deadly sharp in the center field and, for most people, a solid performer. For me, the edges are often distracting and there's a bit too much CA in some circumstances. Eye relief is barely enough for my eyeglasses. If it was the only bin I owned, however, I could be content.
The SLC is better for me for a few reasons. Edge sharpness, though not perfect, is never a distraction. CA control is not perfect but it's rarely a problem. Eye relief is exceptional in the SLC. Weight is not a problem because I carry it bandolier style.
The SLC is my go to 7X42. I cannot part with the Ultravid but, truthfully, I don't use it very much. It's a great loaner!
Mine is a SLC 7X42B NEU and was made in 2008. It features SWAROBRIGHT and Easy to Clean. That's probably pretty close to the last year they were made. It's comes across as the highest quality SLC I have and maybe any Swarovski binocular period. The focus adjustment is probably the best of any Swarovski binocular I've ever owned. Documents included with it indicate:
Diopter adjustment- +/- 3
Close focus- 13ft
One thing I've noticed is previous versions don't have the same case. A few pics will be included at the bottom.
For sure I've never had ANY reason to purchase any other 7X42. This binocular is superb. It lags slightly behind the current UVHD+ and Meostar B.1 in terms of light transmission and with the FL a little more so. In the field of course this is really never noticed. I think this model would be a nice addition for you.
