Okay, let me see if I can recap your review and rank the three bins in the proper order.
1. Zeiss 8x32 Conquest HD
2. Zeiss 8x32 Terra ED
10. Swarovski 8x30 CL
I followed this review more easily than I did the HT/SF comparison. One sentence, however, did confuse me: The CL’s focuser is “smooth and luxurious but is so stiff that I had a hard time getting a focus on even moderately fast birds.”
The words "smooth and luxurious" and "so stiff that I had a hard time getting a focus on even moderately fast birds" in the same sentence seems like an oxymoron (you thought only Arthur knew how to use $10 words!).
I think we can conclude that the CL has yet another "wonky" Swaro focuser. No surprise, but at least it's "smooth and luxuriously wonky."
RE this observation: The CL is a most attractive instrument and in the hand feels worth every penny of the asking price, which makes its modest specifications all the more puzzling.
The modest specs relate to the need to keep the weight down, or at least that's what someone from Swaro (or a Swaro "insider") once wrote. But really, would adding a 1/2 degree FOV make the prisms that much larger as to negate the bin's "companion" travel appeal? It would still fit in the overhead compartment of a plane or in a glovebox of a car. It wouldn't, but it doesn't matter, because the CL wasn't made for birders, so FOV wasn't a priority. I've concluded from the dozens of reviews of the CL I've read that it's a hunter's bin, not a birder's.
If you hunt and want lightweight, diminutive binoculars to find a deer and count how many "points" on the buck's antler, the CL will work just fine. If you want to find birds and look for subtle field markings, not so much. But it wasn't made for that, so comparing the CL to the TED and HD was apples and venison. But it is in the same configuration category and similar price point as the Conquest, so I understand why you included it.
Interesting that you mentioned who might buy the CL, and came to the same conclusion I did not long after the bin's release, namely, those who already own a full sized or midsized Swaro. From the CL owners who posted on these forums, this seems to be the case, though according to Swaro's marketing, that's not the target market CLs were designed for, but rather as an entry binocular to Swaro's "family of optics." Didn't seem to work out that way, but it did work as a "companion" bin for existing Swaro owners, so it was appropriately named.
I'm impressed that you could see more feather detail with the CHD that you could with the TED since the TED is no slouch in the resolution dept., at least the 8x32 model.
Bob and I never see eye to eye with our eyes. I haven't tried a CL but if the CL's edges are better than the 8x32 TED's, then the CL must be sharp to the edge, because the 32 TED has a very big sweet spot, or at least the sample l have right now, and it has .7 a degree more FOV than the CL. The edge sharpness held up in a star test, not quite as good as during the daytime, but better than the other roofs I compared it with, which all have smaller fields of view (8x42 P7, 8x42 M5, 8x42 TED).
I've been using the 32 TED mostly in the backyard, but yesterday I had to drive to the other side of town. On the way back, I stopped at a park at the base of Mount Nittany (where the Penn State football team's mascot's ancestors once lived).
I took some peanuts with me because I feed the crows at the park. They recognize my car and start gathering as soon as they see me pull into the parking lot. I walked up the hill near the ball field and watched as the crows swooped down and took peanut after peanut from the parking lot and hid them in the nearby grass. I couldn't detect any CA watching the black colored birds against the blue sky.
I also watched BOP riding the thermals above the mountain ridge and didn't see any CA around them either. I've also tested the TED with the white soccer goals on the field across from the house and saw very little CA. Not bad even off axis.
The view is very "transparent," and that was particularly noticeable yesterday looking at farther distances where the fast focuser was not an issue. For the price, I could live with the focuser, which isn't as fast as the ultra-fast 8x42's, and would probably be "just right" if it had as much stiction as the 8x42's.
I was disappointed with the 8x42 TED, but surprised and pleased with the 8x32 model.
If I were King of the Forest (head of product development at Zeiss), I'd drop both models and ask the design team to make an 8x36 model with the optics and ergos of the 8x32, focuser stiction of the 8x42, increased focus range from 1.5 to 1.8 turns, use the color and smooth lines of the 8x42, beveled eyecups like the Conquest HD, the better working click-stops of the 8x42 (the 8x32s are "mushy" and don't "click" in place), polycarb body of the 8x32, and throw in the Cordura case of the 8x42 model (no plastic display cases please, I don't have a curio cabinet!).
The 8x36 configuration is a neglected niche. Hawke has one, which has the same design as the ZR 7x36 ED2. You nearly get the compactness of an 8x32 and nearly the light gathering of an 8x40. Best of both worlds.
But alas, I'm not King of the Forest, nor duke, nor prince, nor direct debit and membership and professional development stock and credit administrator, so the configurations will stay as they are and you pays yer money, you takes yer chances. My money (in bit coins) is on the 8x32 TED.
Tomorrow, Steve's coming over with his 8x32 SE "reference standard" and we're going to compare it to the 8x32 TED, 8x42 TED, 8x42 M5, 8x42 P7, and 7x35 Aculon.
