Which one to buy
An older full-size against a newer mid-size, at almost the same money: the Conquest HD 8x42 is $1,000 and the Conquest HDX 8x32 is $980. The HD has been discontinued, and its owners say people hunting for closeouts in 2025 mostly came up empty, so a new one may be hard to find. That alone pushes most buyers toward the HDX.
The HDX 8x32 is lighter at 21.9 oz against 28.0 oz, shows a wider 420 ft field against 384 ft, and focuses much closer at 4.9 ft against 6.6 ft. It pairs ED glass and field flattener optics with a magnesium body, and is rated at about 90% light transmission. The field flattener matters here, because edge softness is the HD's known weakness: its owners say sharpness falls off beyond about 50-60% of the way out, with some color fringing.
The HD 8x42's advantages are light and eye relief. Its 5.25mm exit pupil beats the HDX 8x32's 4mm, which counts in forest shade and at dawn and dusk, and its 18mm of eye relief against 16.5mm works for most glasses wearers, per its owners. They also praise its center sharpness, fast focus and tank-like build, while noting its weight and some glare when panning against backlight. For a birder who often starts before sunrise or wears glasses, a Conquest HD 8x42 found well under $1,000 still makes sense. For everyone else, the HDX 8x32 is the lighter, wider and easier-to-buy binocular.
Zeiss Conquest HD 8x42
Worth it only at a real closeout discount, for birders who need a brighter exit pupil for dawn and shade or 18mm of eye relief for glasses.
Zeiss Conquest HDX 8x32
The practical choice for most: current production, lighter, a wider 420 ft field, closer focus and a field flattener for sharper edges.

What birders say
Zeiss Conquest HD 8x42
- ✓On-axis sharpness that forum veterans say is 'very hard to beat' - some rate its center resolution alongside binoculars costing three times as much
- ✓Outstanding brightness with roughly 90% light transmission - in group comparisons at the $1,000 point, one reviewer judged it best overall
- ✓384 ft field of view - the same width as the Conquest HDX 8x42 that replaced it
- ✓Fast, precise German-made focus mechanism with excellent depth of field - a repeated owner favorite for birding
- ✓Built like a tank - owners describe the German construction as bomber-grade, and long-term reliability reports are excellent
- ✓18mm eye relief that genuinely works for most eyeglass wearers, with Zeiss having supplied longer eyecups free to owners who needed more
- ✓Discontinuation means falling used and closeout prices - the classic sub-alpha benchmark can now be had well under its old $1,000 sticker
- ✓LotuTec hydrophobic coatings shed rain and smudges, and the whole package carries Zeiss's limited lifetime US warranty
- ✗Edge sharpness is its known weakness - the field softens noticeably beyond about 50-60% out from center, well short of a Swarovski EL or Zeiss SF
- ✗Heavy for its class at about 28 oz - noticeably more than an HDX (25.2 oz) or Nikon Monarch M7 (23.6 oz)
- ✗Some eyepiece-sourced glare when panning against bright backlight or silhouetted branches, varying with eye position
- ✗Chromatic aberration is visible in the outer field on high-contrast subjects - well-controlled in the center, less so at the edges
- ✗The diopter adjustment doesn't lock - one of the specific things the HDX redesign addressed
- ✗Discontinued in 2024, so buying new means hunting scarce remaining stock; forum members looking for closeouts in 2025 came up mostly empty
- ✗Included accessories underwhelm for the price - the tethered objective covers in particular draw complaints across Zeiss's line
- ✗The design dates to 2012, and spec-for-spec the HDX offers a lighter magnesium body and locking diopter at the same original price
