Match DHAP Orange Vswabs to your medium format sensor: 30-33mm coverage, pack size, and when the 1.0x full-frame swabs are the wrong choice.
Quick answer
For most medium format cameras with a 30-33mm sensor vertical or horizontal length, the VisibleDust DHAP Orange Vswab for Medium Format 30-33 mm (12 Pack) is the correct fit. If you shoot full frame instead, choose a 1.0x DHAP Orange Vswab rather than forcing a wider swab into a smaller chamber. Buy the 12-pack when you clean occasionally or want a low-commitment first box; step up to a larger pack only when you already know the swab fits your camera.
Why the 30-33mm size exists
Medium format sensors are physically larger than full-frame sensors, so a full-frame 1.0x swab cannot cover the sensor in one controlled pass. The DHAP Orange Vswab for Medium Format 30-33 mm is sized for cameras whose sensor vertical length or width falls in that range, including the Leica S2, Pentax 645, Pentax 645D, Pentax 645Z, Fujifilm GFX 50S, Fujifilm GFX 50R and Hasselblad X1D. If your camera is not on that list, measure your sensor's short edge before ordering rather than assuming any medium format body uses the same swab.
What the DHAP Orange fabric actually does
DHAP stands for the double layer High Absorbency fabric used on these swabs. It is made of super-thin fibers and is designed to clean a delicate sensor without leaving streaks, pooling or abrasion. The patented mini-channels with contour are intended to provide even saturation across the swab surface, and the patented V shape is meant to give better maneuverability inside the camera chamber. In practice, that combination matters most when you are working close to the shutter and want the swab to stay flat and evenly wet rather than dumping liquid in one spot.
Pack size: 12 vs 50
The 12-pack is the sensible starting point because it lets you confirm the swab fits and that your technique produces a clean result before you commit to a larger box. A 50-pack only makes sense once you already know the size is right for your body and you clean often enough that the per-swab cost matters more than the upfront spend. If you are unsure between sizes, buy the smaller pack first; a wrong-size swab is wasted regardless of how many you buy.
When a full-frame 1.0x swab is the better buy
If you also shoot full frame, the VisibleDust DHAP Orange 1.0x Vswabs are the correct match for that sensor size. The 12-pack with bonus CurVswab and Corner Swabs is a practical choice for full-frame bodies because the extra corner tools help with edges the main swab can miss. The 50-pack suits full-frame shooters who clean regularly and want a longer supply. Do not use a 1.0x swab on a 30-33mm medium format sensor and expect full coverage in one pass, and do not use a medium format swab on a full-frame body.
Decision rules for buying DHAP Orange Vswabs
- Match swab width to sensor short edge: Measure the vertical length or width of your sensor. If it falls in the 30-33mm range, choose the DHAP Orange Vswab for Medium Format 30-33 mm. If it is full frame, choose a 1.0x swab. Wrong width is the most common reason a swab fails to clean in one pass.
- Buy 12 first, 50 later: Start with a 12-pack to confirm fit and technique. Move to a 50-pack only after you know the size is correct and you clean often. A 50-pack of the wrong size is an expensive mistake.
- Add corner tools for full-frame work: If you shoot full frame, the 12-pack with bonus CurVswab and Corner Swabs gives you edge coverage the main swab may miss. Corner Swabs are a practical add-on, not a substitute for the correct main swab.

This is the fit check: if your sensor's short edge is in the 30-33mm range, this is the swab width designed for your body.
- VisibleDust DHAP Orange Vswab for Medium Format 30-33 mm (12 Pack): The patented V shape of the sensor cleaning swab results best maneuverability inside the digital camera chamber. Medium format mirror boxes are tight; the V profile is intended to help you angle the swab without scraping the chamber walls.
- VisibleDust DHAP Orange 1.0x Vswabs (50 Pack): Double layer High Absorbency fabric is super soft and made of super-thin fibers, ideal for cleaning a delicate sensor without leaving streaks, pooling or abrasion. This is the reason to use DHAP Orange rather than a generic swab: the fabric is designed to hold liquid evenly and release it without streaking.

Who should buy which swab
Best for
- Medium format shooters with a 30-33mm sensor short edge, including Leica S2, Pentax 645 series, Fujifilm GFX 50S/50R and Hasselblad X1D
- Photographers who want a low-commitment 12-pack to confirm fit before buying in bulk
- Full-frame shooters who need the 1.0x size and want bonus corner tools
Not for
- Full-frame camera owners who should use a 1.0x swab instead of a medium format swab
- Medium format owners whose sensor short edge is outside the 30-33mm range
- Anyone looking for a dry-only cleaning method; these are wet-cleaning swabs
