Variants & identification

Variant	Mount	Years	Serial ranges	Production
MS-MODE-AH APOQUALIA 3.5/50, collapsible, on the MS-51.6 helicoid	LTM (Leica M through a screw-to-bayonet adapter)	2009–2012	N.098 (a copy sold on Yahoo! Auctions, October 2026)	170 according to Phillip Reeve's site. Camera-wiki, citing an archived Hayata Camera Lab page on the January 2009 announcement, says 300 were to be sold, with a first lot of 170. No source records a second lot; asked in November 2012 whether there would be one, Japan Camera Hunter replied that the lens had been discontinued.

Weight: 90 g in Japan Camera Hunter's 2012 listing, in shige's table and on Phillip Reeve's site; Lars-Göran Hedström gives 115 g. Camera-wiki, from Hayata's announcement, gives 90 g for the lens and 115 g as a set, which probably accounts for both figures.
Minimum aperture: f/22 according to Hedström and to the comparison table on shige's own page for this lens; shige's MS Optics overview table gives f/16. The copy photographed for auction in 2026 has a depth-of-field scale running to 22 on its helicoid.
Closest focus 0.8 m (Japan Camera Hunter, Hedström, shige), 0.85 m (Phillip Reeve). Shige says the rangefinder stays coupled down to the closest distance. Size: 38 mm long and 49 mm across (shige); Reeve gives 38.5 mm extended and 50 mm. True focal length 51.6 mm (Japan Camera Hunter, Hedström); Reeve gives 51.9 mm and f/3.58.
Dates: camera-wiki has MS announcing it in January 2009 for release in February; shige and Japan Camera Hunter give 2009; Reeve gives December 2009. The 2012 end date rests on Japan Camera Hunter's replies of 8 November 2012 (the lens had been discontinued) and 22 November 2012 (its stock had sold out). When the last copy was made is not recorded.
The 12-blade diaphragm is German-made (Japan Camera Hunter); Hedström names the maker as Otto Niemann Feinmechanik of Berlin, which Reeve's site says supplies most MS diaphragms.
Some Japanese listings give the mount as Leica M; the 2026 Yahoo! Auctions title says Mマウント. Japan Camera Hunter, Hedström and camera-wiki all give Leica thread mount, and the copy sold in 2026 has a screw thread. Shige's comparison table also says M, probably because the lens is used on M bodies through an adapter.
Market: copy N.098 sold on Yahoo! Auctions on 4 October 2026 for ¥50,050 including tax (¥45,500 before tax) after 26 bids, from a ¥1,100 start, described as used with marks. This was a store auction's final bid, not a list price.

How to tell them apart (expand)

The only 50mm f/3.5 MS made with APOQUALIA on the ring. The later Xenomax 50mm f/3.5 and Lumitar 50mm f/3.5 are different lenses with their own names engraved, and neither sits on a separate MS-51.6 helicoid; the Lumitar also collapses (Reeve), so collapsibility alone does not identify this lens
Black throughout, with no chrome; the separate MS-51.6 helicoid gives it a two-piece look

MS-MODE-AH APOQUALIA 3.5/50, collapsible, on the MS-51.6 helicoid:

Front ring engraved MS-MODE-AH, then a serial in the form N.098, then APOQUALIA 3.5/50, white on black
Collapsible: the lens tube slides into a separate black helicoid engraved MS-51.6, with a focusing tab, a distance scale in metres and a depth-of-field scale to 22
Male Leica screw thread at the rear; on an M body it needs a screw-to-bayonet adapter
Clickless aperture ring behind the front ring, red index dot, scale from 3.5
30.5 mm filter thread in the front ring; the hood fits the outer ring of the lens

MS-MODE-AH APOQUALIA 3.5/50, collapsible, on the MS-51.6 helicoid: The only version made. It is engraved MS-MODE-AH, which shige says he was told stands for Apo-Heliar or Apoqualia-Heliar. The Yahoo! Auctions seller of copy N.098 titled it MS-MODE-HA, but the ring in the seller's own photographs reads MS-MODE-AH. The same title called it "Mマウント", but the photographs show a screw thread at the rear and no adapter. Hedström received his copy in M39 thread and used a Voigtländer M39-to-M adapter (the 50/75 frame type) on his Leicas. Japan Camera Hunter wrote on 8 November 2012 that the lens had been discontinued, and on 22 November 2012 that it had sold out.

Serial-range notes

N.098: The one serial seen in a photograph: a black copy on its MS-51.6 helicoid, sold on Yahoo! Auctions by a store seller on 4 October 2026, photographed with a capped hood. No numbering scheme has been published. A three-digit number below 170 is consistent with the reported first lot, but one copy proves nothing about where the numbers start or stop.

Original price: ¥59,850 including tax at launch in February 2009, the figure camera-wiki gives from an archived page of Hayata Camera Lab, one of the few shops that sold MS lenses. shige's MS Optics table gives a list price of ¥65,000 before tax, and Japan Camera Hunter, a Tokyo dealer, offered it at ¥65,000 in June 2012 without saying whether tax was included. The launch figure and shige's list figure do not agree, and neither source reconciles them. (today ¥68,000)

What reviewers say

Lars-Göran Hedström (Japan Camera Hunter) (blog) — Used on a Leica M9 and M4-P alongside the Perar 28. Sharp in the centre, with sharpness and colour contrast its strong points, and almost no vignetting or distortion. Edges and corners go soft, with some coma, and pixel-peeping at 100 per cent shows lateral chromatic aberration, which he said would not matter for most of his pictures. Focusing is quick and exact with a quarter-turn throw; at first his copy would not focus to infinity because the helicoid was heavily greased, which settled quickly with use. There are no aperture detents.
shige (Shige's hobby) (blog) — Tested on Leica M10, M-P 240, M9 and M8.2, Epson R-D1xG, Leica T and a Hasselblad X2D-100C. With few glass elements it draws crisp, clear images from full aperture, a lens for connoisseurs. Background blur is fair, but on high-resolution sensors branches can double. The image circle covers the 44×33 mm sensor, with soft edges wide open that improve by f/5.6. He suggests the Xenomax 50/3.5 as the easier lens to find for anyone not set on a Heliar.

History

The Apoqualia 50mm f/3.5 is the second lens Miyazaki Sadayasu designed himself rather than converted from another maker’s glass. It followed the MS-Mode-S 50mm f/1.3 of 2006. Camera-wiki, drawing on an archived Hayata Camera Lab page, has MS-Optical R&D announcing it in January 2009 and selling it from February at ¥59,850 including tax. It was a five-element, three-group Heliar in lanthanum glass, collapsible, in Leica thread mount, with a 30.5 mm filter and a 12-blade German-made diaphragm. Its true focal length is 51.6 mm, it focuses to 0.8 m and the lens weighs 90 g. Shige calls it the only Heliar type MS ever made: what followed, he says, were Sonnars, Gauss types and, rarely, retrofocus designs. The Apoqualia name went on to MS’s fast lenses, the Apoqualia-G 35mm f/1.4 and the Apoqualia 28mm f/2 among them, and shige points out that this one does not share their wide apertures. Shige also recalls the shop owner who sold it complaining that, after the f/1.3, this was a specification that would not sell well.

Very few were made. Camera-wiki’s reading of the announcement is 300 to be sold, starting with a first lot of 170. Phillip Reeve’s site says only 170 were produced, and nothing has surfaced to show a second lot. Japan Camera Hunter offered the last of the stock at ¥65,000 in June 2012, in very limited numbers, and wrote in November 2012 that the lens had been discontinued and then that it had sold out. Shige’s MS table gives ¥65,000 before tax as the list price, which does not match the launch figure. There is only one version. The front ring reads MS-MODE-AH, a serial such as N.098, and APOQUALIA 3.5/50. Shige was told the AH stands for Apo-Heliar or Apoqualia-Heliar. The lens tube collapses into a separate black helicoid engraved MS-51.6, the same designation auction sellers give the helicoid under the MS-Mode-S. Sellers sometimes write the model as MS-MODE-HA and sometimes call it M mount. The copy that sold on Yahoo! Auctions in October 2026 had both errors in its title, while its photographs showed the AH ring and a screw thread at the back. It sold for ¥50,050 including tax after 26 bids.

Both published users found it sharp in the centre; shige says it draws crisply from full aperture. Lars-Göran Hedström used it on an M9 and an M4-P through a Voigtländer M39-to-M adapter. He praised its colour contrast and found almost no vignetting or distortion. He saw softness, some coma and lateral colour in the corners, which he decided would not matter for most pictures. Shige shot it on digital Leicas and on a Hasselblad X2D. Its image circle covers the 44×33 mm sensor with almost no vignetting; the edges break up wide open and improve by about f/5.6. The later MS 50mm f/3.5 lenses are the Xenomax of 2022, a Xenotar type that Reeve’s site calls the successor to this lens, and the Lumitar of 2025, which Reeve describes as retractable. Shige compares it with Voigtländer’s Heliar 50mm f/3.5 of 2001, made for the Heliar’s 101st anniversary with the same specification, and says he does not know whether Miyazaki had it in mind.

When buying, check that the copy is complete and moves freely. A new lens came with a dedicated hood that fits the outer ring; Hedström’s could be reversed over the lens. Shige suggests the 30.5 mm Contax TVS metal hood T-550 as a substitute if the original is missing, gold though it is. At first Hedström’s copy would not focus to infinity because its helicoid was heavily greased, which settled quickly with use. Check infinity on a little-used copy, and check that the collapsing tube slides out and back smoothly. The aperture ring has no detents, so check the setting before each shot. The lens is a screw-mount lens, so on an M body the adapter decides which frame lines appear, and a listing that says M mount should show which adapter it includes. MS also mounted other makers’ glass, EL-Nikkors among them, on helicoids of the MS-51.6 type, so the ring should read APOQUALIA.
