Zeiss Conquest HD 15x56

Over the years I’ve been fortunate to be able to use some of the best optics made. Usually, that top shelf includes Zeiss, Leica, and Swarovski. Generally, I’m the type of hunter who is in the timber, tight to what I’m hunting. When a last-minute Idaho mule deer hunt fit into my schedule this past fall, I jumped on it. Lucky for me, Rokslide needed a set of 15×56 bino’s reviewed. Que the Zeiss Conquest HD 15×56. Although they’d be perfect for my mule deer hunt, I planned on using them for my other species’ hunts too.  Right off the bat, I was impressed with the packaging presentation. Does it add any value to the binocular itself, absolutely not, but it sure does add to the total experience. Well done.

Included in the box

Binoculars, lens covers, cleaning pads, shoulder strap, and tripod adapter. Yes, you read that right. Included tripod adapter–an added value of $130. This was another nice touch  adding to the experience.  A few other specs:

Zeiss Conquest HD 15×56
  • Magnification: 15x
  • Lens Diameter:  56mm
  • FOV @ 1000yds: 240 ft
  • Close focus: 12 ft
  • Eye Relief: 18mm
  • Water resistant: 400mbar
  • Length: 8.27 inches
  • Weight: 45.7 ounces

As this was my first set of high-power tripod mountable binoculars, I was about to jump head first into something I knew nothing about; but between high-end spotters, binos, and rifle scopes, I knew I had the optics needs covered. Some long-range reconnaissance was about to take place.

Wyoming Elk

My season started with archery elk season in early September on a Wyoming mountain. I packed in the Zeiss Conquest HD 15×56’s, a pair of Leupold 10×42 BX-5, and a Leupold RX-1600i rangefinder. I knew, for the most part, I would be in tight and not need the high-power glass, but I wanted to be able to use it in some situations if given the opportunity. I’m glad I decided to take them, even though on the pack-in I was questioning it. They are listed at 45.7 ounces. With the tripod adapter and case, they are closer to 56 ounces.

On the first morning just after daylight, I spotted a herd of elk high above me, just about at treeline. They were a long ways, and the 10x showed a couple of bulls, but I couldn’t see any details. Shooters or not? It took a couple of extra minutes, but I pulled the big 15x out and steadied them on my bow. A little shaky, but I could now see the frames on those bulls, and one of them was big. The 15x told me what I needed, it was time to climb.

Not Right For Every Situation

I found that as the hunt progressed, I started to leave the big bino’s in camp, it was just too much weight for the return I was getting on them. They had their place, but dark timber archery hunting was not it.

Once I tagged my Wyoming bull, I was back home for 10 days. I would repack for Idaho mule deer and head West again. If you followed along on Another Season you know this would be my first rifle hunt out West, my first mule deer hunt, and my friend Jenn’s first with a rifle and for mule deer. Our plan was to put these big binoculars to the test, and that we did.

Idaho Mule Deer

For this trip, we packed the same optics but also threw in a pair of Zeiss Victory SF 10×42’s and a Swarovski HD 65mm spotting scope. We threw the Conquest’s and the spotter on the tripod and then had the 10x’s chest mounted. It was a good set-up. We could glass quick and close with the 10x, then switch to the tripod mounted set-ups if we needed a close look at something. Once we reached the edges of the 10x range we switched over to the tripod mounted glass. Here we picked the nooks and crannies, peering into the shadows of the early morning, looking for movement of those feeding bucks. As the sun got high and then progressed into afternoon and evening, it becomes a total game of the tripod-mounted optics. We spent hours breaking down the shadows. It was tedious looking for ear flickers, antler tips, and tail wags.

Feel and Ergonomics

Although these were tripod mounted for 90%+ of the trip, the feel is worth noting. Right out of the box I could see and feel the body armor. It is a nice soft and warm feel. The tapered body has a hinge mounted focus knob. This knob really jumped out at me. It was smooth and fast, needing little effort to readjust. This allowed quick, easy movements, to refocus as animals were spotted. Very convenient. The tripod adapter sits at the other side of the hinge.

The diopter was a little different though. Located in front of the right eyepiece, it’s a no click, non-locking adjustment. The ring on this particular set was very tight. It definitely needs to be tighter than the main focus knob so as not to be inadvertently moved, but this was too tight for my liking.

Glass Performance

Light transmission is quoted at 93%, due to the Abbe-Konig prisms. The eyepieces are rather large 25mm lenses that yield a nice almost 70-degree field. The eyecups themselves have a very nice, appealing feel. Easy to sit behind for hours. Although rotationally they seemed choppy throughout the different adjustment locks.

The view is excellent. Sharp and detailed, with good brightness at first and last light. During the heat of the day, per typical, the heat waves were noticeable. Not unexpected. In the evenings, the binoculars definitely increased our number of spotting minutes, penetrating the shadows and adding precious time to spotting those reclusive bucks.

We spent a lot of time behind those binos over that 8-day hunt. Although we didn’t punch tags, the binoculars left us feeling comfortable that we didn’t miss anything. It was nice to be able to break up sitting beyond a spotting scope, with the dual eyepiece of the binoculars. It would allow the eyes to rest a little. Next up would be a West Kansas whitetail hunt.

Kansas Whitetail

I do believe I found the perfect use for these binoculars, although heavy, the Kansas terrain was the ideal use. For miles, there was nothing but open, rolling terrain. Lots of hills, coulees, and draws filled with sage, brush, and a lot of space for big whitetails to hide.

While in Idaho they worked well, but there were many times when the 15X couldn’t cover the distance that the terrain allowed us to see, so we would have to jump behind the spotter. Kansas, on the other hand, was built for this setup. There were times where we would drive and glass right from the truck. Mostly though these worked great for glassing those long ravines that had multiple coulees winding up out of them. The deer were bedding in these areas and then working up to the tops, or out of the bottoms. With the Zeiss Conquest HD 15×56 mounted on the tripod, I could glass those distances 200-1200 yards really well. After spotting them, I could also then determine if they were of enough quality, to want to put a stalk on. I’ll definitely run a setup like this anytime I do that hunt or a similar hunt in the future.

The nuts and bolts of the Zeiss Conquest HD 15×56

These are an excellent binocular. Having never used 15x, I wasn’t sure what to expect. Having used Zeiss binoculars in the past, I had a preconceived expectation of the quality. I wasn’t disappointed. These provide a great view at this power, with excellent edge-to-edge, lowlight optical clarity. The body armor is comfortable and easy to hold, and the focusing knob was smooth, fast, and easy while holding. The eycups are removable for easy ocular lens cleaning. The prefered method is washing away the field debris under running water. Another nice touch is the included tripod adapter, for where these binoculars really shine, on the tripod.

Really the only downside that I found with them is the weight, although the Zeiss Conquest HD 15×56’s are comparable in weight to the competitors in this platform. For someone like me who cuts and trims ounces in every imaginable area, the three-plus pounds is a tough pill to swallow on a backcountry hunt. It’s a non-issue for a base camp hunt. Even the $1,799 retail price set on these isn’t really a downside. You get what you pay for in optics, and I think this is a good price on a great binocular.

Les Welch has been hunting and shooting for over 30 years. He grew up chasing small game and whitetails in the big woods of Northern Wisconsin. Having the ability to roam for thousands of acres hunting, scouting, and exploring without seeing people and civilization ingrained the public land DIY mentality deep within. After harvesting dozens of whitetails with archery equipment, including many P&Y, and countless more with rifle and muzzleloader the desire to explore the mountains had become to much to overcome. In 2006, he started researching antelope. That led to the harvest of 6 DIY, public land antelope in 2007 between him and his father. That trip was the beginning of the obsession/addiction. Since that trip he has traveled West of the Mississippi on 8 more hunts, all 100% DIY public land.....with 100% success rates, harvesting multiple elk, mule deer, and antelope. Coming home to the flatlands after that first hunt back in '07 he realized the need to be in shape if success was going to continue. He dropped 60# and 20% bodyfat in a few months. He has since become a certified Personal Trainer and Fitness Nutrition Coach. Understanding what the body needs to maximize performance whether he is running a race, competing in triathalons, or preparing for 15-20 day backpack backcountry hunts help insure he achieves full potential. Year around gym time, training, scouting, and spending time in the outdoors with family maintain that healthy lifestyle to keep "mountain" ready! He is on pro-staff for Sitka Gear, HECS, and ElkNut Outdoor Productions. When he is not chasing down something with stick and string, rifle, or muzzleloader he can be found spending time hunting, fishing, camping, or something of the like with his family. You will also see him at many of the RMEF events as he is Chapter chair in Wisconsin.
