Incidentally, I just bought a pair of Zeiss FL 10x32 a week ago from the same dealer. An incredibly sharp pair with a very wide AFOV and TFOV. And just so tiny and comfortable to hold. So I took those 10x32 FL's and the 10x42 HT's out for a first daytime test. Here is what I found:
The new HT's are beautifully made binos. And the views bright, with an electrifying touch to the image. They are also a bit longish. The adjustable eyecups are the same as in the FL's, with a bit less resistance when resting in the stops. Focussing is light and responsive. Ergonomics are good. The AFOV and TFOV are less wide than in the 10x32 Victory. Amazingly, the 10x32 are a bit sharper during the day. Not quite as bright, but sharper. Difficult small details reveal themselves in the tiny 10x32's first. Hmmm.
Under the stars, the HT's are brighter, but the FL's images are tighter, more apo-with-nagler like stars. The viewing experience wider and more immersive. Edge of field correction better. And at 10x, the 32 FL's easily fit in both the Belt and Sword of Orion, while the 42 HT's can't quite manage that.
I also tested the sharpness on a solid tripod with my Zeiss 3x12 mono to magnify the image to 30 times. Starimages where noticeably tighter in the 10x32, with perfect tight pinpoint stars. In the 10x42 HT stars were not quite as tight and didn't quite have the nice intra- and extra-focal images the 10x32 showed.
Long story short, I decided not to buy the 10x42 HT's. However, I did find I really enjoyed the brightness of the 42 mm bino's and set out to find a bino that would team up with the 10x32 FL's and have better brightness and a wider TFOV.
Since I already tested 8x32 FL's and 8x42 FL's with the same AFOV and TFOV as the still unavailable 8x42 HT's and found those FOV's still on the small side for my taste, I decide to take a different approach. I'll share that below, but first a picture of the Zeiss 10x42 HT's and 10x32 FL's.
