Konica Hexar RF

AE, Motor, Leica M mount

After rumors for about three years or so,  Konica finally introduced the Hexar RF on October 13, 1999.  The new Konica is the first substantially new M mount camera body since the M6 in 1984, discontinued October 2003.

Imagine starting with a Leica M6, adding AE exposure with AE lock, motorized film advance and rewind, a great finder shutter speed display, and an electronic metal shutter with a wider shutter range:  that's the  Konica Hexar RF -- more or less.     The Hexar RF is an excellent camera.  With some features that no Leica M had until the introduction of the Leica M7 in 2002.   I expect  some Hexar RF's finding  themselves into a Leica  bag, working besides an M6 to offer the photog the best of both.   Another way to look at the Hexar RF is as a grown up Minolta CLE with AE lock, metered manual, a wider shutter speed range, and motorized film advance added -- but with the TTL flash taken away.

How good is the Hexar ?  Excellent indeed.  Feel and fit are up to Leica standards.  If it had the better Leica finder,  I would have little trouble believing a Leica label on the top plate.  Very simple well placed intuitive controls help make this camera a pleasure.    The standard top and bottom covers are Titanium- a very nice touch.

Leica Copy ??

Did anyone say "Leica Copy"?

The Konica RF's  Rangefinder / Viewfinder is very similar to the Leica M6.  Curiously  the Hexar has the SAME framelines as the M6: 28, 35. 50, 75, 90, 135.    Konica uses the SAME framelines combinations as Leica:  28+90, 50+75, 35+135 which are automatically selected when you mount the lens, and even uses the same type of frame preview lever in the same M location.   Wow, what an amazing coincidence that Leica and Konica came up with the same framelines and frameline combinations -- what are the chances of that happening??   More amazing is that the internal design seems to be a obvious copy of the Leica M.   This near clone of the M6 finder (at least from the standpoint of bare specifications) is a first.  No other camera  manufacturer, including Nikon or Canon or Zeiss, ever manufactured a viewfinder as complicated as the Leica M.   The obvious question is whether it was done with Leica's  help.    Despite rumors to the contrary, the answer seems that it was not.  It turns out the Konica Hexar RF finder is produced by a prominent Japanese wholesale supplier with little retail recognition, which strangely also produces the finders for the Contax G2 and Fujica/Hassy Xpan.  While all of excellent quality, all are definitely a bit darker than the Leica M or Voigtlander Bessa R.  

Alas, the Konica's framelines are not quite as bright and easily seen as in the Leica M6 finder -- though they are still quite bright.     The Hexar's brightlines can sometimes have bright/dark line patterns in them --  for reason's I don't understand.  The Hexar RF rangefinder patch is slightly  smaller than the M6, but just as a tad less bright    at least to my eyes.  It would be interesting to measure and  measure each camera's finder and rangefinder brightness, but I do not have that capability.   

The Hexar RF's viewfinder/RF is not as bright as a Leica M, or a Voigtlander Bessa R.  You need to keep your eye centered in the rangefinder exit pupil --  a bit one way or the other and the image will seem to be out of focus when it isn't.  The smaller image size of the framelines make it better suited for 50mm lenses and shorter in my opinion.  The 90 frameline is OK depending upon the subject, but the 135 frameline is so small you will probably have a hard time framing what you are shooting.   On the other hand, the 28 and 35 framelines are more usable for glasses wearers than any Leica M camera except the .58.   The .58 M6 does have a noticeably better finder than the Konica RF, but the Konica RF has features not found on any other M camera.

The Hexar's  LED finder readouts are easily seen and read --the best shutter speed finder readout I have ever seen in any rangefinder, but some photogs consider the readout as being too bright and distracting.   See for yourself if you like it.  On AE, red LED shutter speeds are lit in a bright vertical display on the left side of the finder. Though the actual shutter speeds are steplessly set on AE from 1/4000th to 16 seconds, finder display are limited from 1/4000th to 4.  On AEL (AE Lock), the shutter speed stays the same as long as you keep slight pressure on the shutter release.    On manual, the suggested shutter speed stays lit, while the manually set shutter speeds blinks in Red.  Also visible in the finder are exposure compensation warnings and flash ready signal (with a dedicated flash unit).    In use, this finder display system is very easy and convenient.

AE Exposure Compensation trick: Meter and use AE lock, then adjust the f/stop to compensate as you like, take the shot.  It's simple, easy, and fast.

Viewing area is 85% at 3 meters, and becomes less as the lens is focused to infinity which increases the lens' angle of view (yeah, weird I know, but optics are like that).    The Hexar has the SAME rangefinder baselength: 69.2 mm as the Leica M.   Curiously, the Hexar's image magnification is lower at .6 (same as the Leica CL) instead of Leica's .72 or .85, resulting in an effective rangefinder baselength of 69.2 x .6 = 41.5 which is 83% as accurate (all other factors being equal) as the .72  M6.     In practical terms this means the Hexar will be easier to use with the 28 and 35 for eye glasses wearers, but won't give the focusing accuracy needed for the 50/1.4 or faster, 75/1.4, 90/2, or 135/4 wide-open at the closest focusing distance.

The Hexar RF's controls are superbly laid out, intuitive to use, VERY convenient and fast working.  Top left shows the LED frame counter and battery check.  The five function shutter speed dial and collar controls the on/off, single advance, continuous advance, self timer, and AE hold when slightly depressed.  The shutter speed dial is ideally positioned at the corner of the camera to be movable while the camera is still held to the photog's eye.   The manual shutter speeds are 1 to 1/4000th plus B.  AE stands for automatic center weighted aperture control.  The AEL stands for AE Lock, which provides the important exposure hold on AE.  The film speed and exposure compensation are set with the larger dial.   The battery check next to the LCD frame counter is ALWAYS visible, even if the camera is off, a nice touch.  If you don't see it, you know you have a dead battery.

The Konica Hexar RF sports the phenomena of swing open back door film loading - something rare indeed in M mount cameras.   Those gold contacts in the film chamber set the automatic DX film speed from the film cartridge, but you do have the option of manually setting the film speed.   The film loading and automatic rewinding is much much faster than with a Leica M.

The preview frameline lever works just like the one on the M6;  I wonder where Konica got that idea.   The metering cell in the film chamber reads reflected light off the gray metal shutter curtain.

Shown are the Hexar's vertical travel metal shutter and easy automatic film loading.  It's fast and easy, worth the price of batteries in my opinion.    Too bad the Hexar RF does not have the all but silent "stealth" film advance of the earlier Hexar AF.  Although the Hexar RF does not presently have a data back, one apparently has been provided for in the future considering those gold contacts next to the film channel.  The early production Hexar I examined had a much louder shutter than I would have liked.  The later Hexar I used  six months later was much quieter,  with a noise level now down to an acceptable level.  This later Hexar sounds like a quiet motorized SLR, but is still nosier than a Leica M6.

Konica M Lenses: Konica initially offered three M mount lenses, the 28/2.8, 50/2, and 90/2.8.  All exhibit very high craftsmanship and have a great feel to working them.  The focusing ring on all three is heavily ribbed and very convenient.  With Konica long standing excellent optical reputation, it's a fairly safe bet all are excellent performers, though probably not equal to the more expensive Leica M lenses.   User reports of the Konica lenses have turned out to be impressive.   Some people consider the Konica M optical quality comparable to Leica.   The 50 and 90 have built in hoods. The 28 is supplied with a separate hood.  The lenses are supplied with caps and leather pouch.   An ODD thing about these  lenses is that if you put them side by side their Leica equivalents, the Konica lenses appear to be the better made with heavier construction!  OK, I know it's Leica heresy even to suggest such a possibility, but try putting the new Konica M lenses side by side current lens offerings from Solms, and  draw  your own conclusions.   

The 4th Konica M series strangely turned out to be a 50/1.2, sold in the Konica new limited edition millennium kit of 2001 units, to be sold, strangely enough, in year 2001.    A new design 35/2 was released in 2001.  In March 2002 Konica announced a new 21-35 f/3.4-f/4 dual focal length lens.

Unfortunately serious doubts about 100% compatibility of Leica M lenses to Konica Hexar RF bodies must logically extend to the Konica M lenses.    IF you buy a Konica M lens, I suggest shooting it wide open at its closest focus distance to see if that particular lens focuses correctly with that particular body.   Focusing errors, if they exist, will show up wide open and at the closest focus distance, and can easily be masked at medium and small apertures at medium and far distances.

The Why Can't Leica Do It ? Department: If Konica can put together beautiful packaging like this on the standard Hexar RF, why can't Leica do it on the higher priced standard Leica M6 ?  I don't mean the kit, I mean the higher level of quality packaging.  

 

 


To me the Hexar RF is most  interesting for what it is not:  a clear knockout of the M6.        Konica could have made a far more sophisticated camera which just buried the M6.   Instead, Konica selected improvements which make for a not so clear choice that  allows the M6 to compete in the marketplace.    Why?  Part of the answer seems to be that the RF was not originally a Konica design, but came from another Japanese company.  

Desirable features Curiously NOT in the Hexar RF design: 


The Funniest Thing About the Hexar RF

If you visit the Konica Hexar RF website in the Q/A section, it will tell you that the "RF" stands for "Rangefinder" and "Focal" plane shutter.  Right, sure it does.  

It's  more likely the Design Department knew what RF stands for (RangeFinder), but did not bother to tell the Know-it-Alls in Advertising.    I'm looking forward to find out what these  photographic pundits claim "35mm" stands for.



Photokina September 2000: Not a company to be left out in the cold with all the new limited edition millennium coming out, Konica announced the Konica Hexar RF Limited.  2001 units will be made for the year 2001, a Hexar RF with chrome colored titanium covers and a new 50/1.2 Hexar M lens.   Apparently the 50/1.2 is only being sold with the 2001 Limited Edition body -- a rather strange marketing decision it seems to me.    Each camera and lens   will have matching numbers from 1 to 2001.    Expected delivery late March 2001,  Japanese list price about $3500 for camera and lens, offered for sale world wide.  A new design 35/2 should arrive in 2001. 


Some Hexar RF users report focusing problems with Leica M lenses, others do not.  How could that happen?

The EXACT cause of this is a hot source of controversy on the net.   Konica is not helping the situation.   So far, I have received different answers from every Konica employee I have discussed the issue with.  Konica USA offered to adjust the rangefinder of my camera, but admitted this would not be a complete solution.   I am told Konica UK actually offers to correct Hexar RF bodies to Leica M specs, for a fee.   Konica USA seems to give me a different answer every time I talk with them.

Some people swear nothing is wrong with the Hexar RF with Leica M lenses, because THEIR camera has had no problems.  Others report focusing problems.  Personally MY Hexar RF did NOT have correct back focus specs for Leica M lenses -- I had it repaired.

I believe the KEY to the controversy is the INCONSISTENCY  -- some people have back focus problems, others swear THEY do not.    How could that happen?

As suggested to me by a Konica insider, the answer may be the plus/minus tolerances used by Konica.   In this scenario, depending upon how a particular camera body's set of parts tolerances add up, that particular camera MAY or MAY NOT exit the factory with back focus specs within Leica lens   tolerances.   I am not sure this is the solution, but I know of no other explanation which satisfactorily explains the inconsistent results reported by Konica Hexar RF shooters. 

Some internet sites make a seemingly strong argument that there is NO Hexar RF back focus problem.  Ask yourself a few questions before you buy into that line of thinking:

  1. Hexar RF problems came into the public eye because SOME, not all, Hexar RF owners definitely were not getting sharp shots with the same lens on their RF, as they were from Leica bodies.   If there was no problem with the RF, what was the cause of these focusing problems?

  2. If there is no problem, why does Konica UK offer a repair service to adjust Hexar bodies to focus Leica M lenses?

  3. If there is no problem, how did the Konica factory correct it on MY Hexar RF?

  4. If there is no problem, why hasn't Konica publicly said the Hexar RF is fully 100% compatible with Leica M lenses?  This controversy is obviously hurting Hexar RF sales.   It would be to Konica's advantage to deny it and put the question to rest, IF there was no problem.   Instead, Konica has publicly side stepped the issue, saying that the Hexar RF is compatible with the Konica "KM" mount.  I interpret Konica's stance as another way of saying "We are not promising Leica M compatibility, because we don't want to pay for a camera recall."

  5. Do you see any of the sites claiming there is no problem, offering to buy back or repair Hexar RF's bought on THEIR recommendation which turn out NOT to correctly focus Leica M lenses?

If you own a Hexar RF, or plan to buy one, I suggest taking it to a Leica repairman, and have them check the film plane and focusing accuracy, just to be sure -- ideally with both Konica and Leica mount lenses.   

Quick and Dirty Hexar Back Focus RF test:  With your RF mounted on a tripod, focus on INFINITY wide open with your WIDEST lenses.  The Voigtlander 12 and 15 are especially useful to spot if your Hexar RF is not up to standard Leica M mount back focus specs.  As a control point, shoot the same shots with a Leica M body you know to be in good shooting condition.   Compare with a loupe.   IF the results are identical, wonderful.    IF you get different results with the same lens on different bodies, consider having the back focus of your Hexar RF checked by a repair tech.

Konica Hexar RF and Konica:  RIP

The Konica Hexar RF is an excellent camera with excellent lenses.   It remains the best motorized 35mm Leica M film choice to avoid Leica's dreadful and expensive M motors.  Unfortunately top Konica management saw it as a prestige "flagship" item for Japan's oldest camera maker, instead of a camera system which could be successfully marketed for a profit.   As a result there was zero marketing effort in the US, and surprise of surprise,  not enough sales.  Who could have seen that coming?  The camera was discontinued without official notice that I am aware of by the end of 2003.  In early 2005 the Konica camera division disappeared in a merger with Minolta.  In early 2006 Konica-Minolta was eaten up by Sony.  So where does this leave the proud Konica Hexar RF owner wanting factory authorized service?  As near as I can find out, pretty much SOL.  There are however still a few independent repair techs who are willing to tackle the intricacies of this virtually impossible to repair if it needs electronic parts camera. 

Konica Digital Dreams

According to two completely independent sources, Konica had working Hexar RF Digital prototypes  behind the scenes when the ill fated Epson RD1 digital was introduced in Las Vegas at the 2004 PMA show.  One version had an APS size sensor, the other full frame.  I have no other info.   Oh well.   Digital will never catch on anyway.
