I would pick the KX over the MX as it's bigger and the matching needles are easier to use.

I didn't pick one over the other . . .

KX: Fixed focusing screen, glass. With microprism or split-image focusing aid.

MX: User interchangeable focus screen, plastic. Stock screen split w/micro.
Many other types were offered but they're difficult to find. LX screens fit, too.

Many rave about the big bright viewfinder image of the Pentax MX.
But others - myself included - find the KX easier and faster to focus.

Thank you all for the responses!

I've read somewhere online (can't remember where) that the big seling point of the MX was it's huge viewfinder, roughly the same size as the Olympus OM1.

I've used a frined's OM! and, oh MY GOD!! It's amazing!


I've never used a MX, is that really true? Is the viewfinder that good????

The MX apparent viewing distance is less. This forces you to move your eye about to see all areas of the image.
The KX screen appears slightly further away and is easier to see in a single glance.

The MX exposure LEDs sometimes seem to disappear in bright light and are an advantage only in near-darkness.
The KX analog match-needle and scale exposure display is more intuitive and far easier to see in moderate to bright light.

My major gripe with the MX finder is that semicircular shutter speed display intrudes deep into the screen,
obscuring part of the viewing area, thus making composing more difficult.

Size matters in this case. IMO the MX suffers over-miniaturization. For ergonomics the KX wins hands down.

The MX viewfinder is VERY good and bright. Use one and you'll never like a dSLR. I even like the LED meter readout indoors, but in Texas, in normal sunglasses the LEDs are very hard to see at all for the contrast of the bright screen. The Leica M6 & R6 both have an over/under LED system, but are much easier to see in bright light. Of course, they are a generation newer...
Here's an MX- K-5 VF comparison

* Truth be told, I consider the Nikon FM2 to better than either the KX or MX except that it does not support K-mount.
Tank versus APC.

Yoshihisa Maitani was a genius when he designed the OM-1 bestowing on it the largest viewfinder magnification on the smallest fullsize 35mm SLR . . . at the time of release. Well, Pentax released the MX later and made it even smaller and gave it an even larger magnification viewfinder. It is still the smallest full manual 35mm SLR with the largest viewfinder.



Unlike the OM-1, the MX shows aperture in the viewfinder, uses the newer available battery and has the shutter speed control in the more traditional location.

The K-series use the spotmatic platform for the bayonet mount, and added a slew of upgrades
The M-series was a step up in size while retaining the quality of the old asahi cameras
The MX, was the flagship until the arrival of the LX and according to Dimitrov
This is one of Pentax's simplest and most robust cameras. It features manual focus, manual exposure and fully manual flash operation. It is fully mechanical, and uses batteries only for its light meter. The MX does, however, offer DOF preview, self-timer, interchangeable screens, and interchangeable backs. The viewfinder offers an optical readout of the selected lens aperture and shutter speed as well as five LEDs that indicate how far the manually-set exposure is from the camera's recommendation: 1 EV or more under, 1/2 EV under, identical, 1/2 EV over, 1 EV or more over. The camera is extremely small, light, and easy to use. A winder and motor drive are available as optional accessories.

I would not agree that the MX was the flagship. I would say that the K2 DMD was, as it remained in production until 1980 when the LX replaced it.

The MX was a suprb little camera with a full system aimed at those professionals and serious amateurs who at the time (and there were still many) disliked the idea of auto exposure so much that they did not want it even as an option, such as the K2 had. Also, while the MX was good for professional reportage and candid, its small size lacked the "profession presence" needed in many situations. When a professional does a publicity shoot, the client is not impressed if the pro has a camera that looks much like his own amateur SLR; and at weddings, where crowd control is part of the job, a big camera acts as a symbol of authority. TBH, bigging up a 35mm SLR is partly what motor drives were for (and today's DSLR battery grips), and it's why some pros shot weddings on 35mm in a film back on a Bronica or Mamiya 67.

The K2 DMD was Pentax's first foray into the professional world and, although I loved my MX, I think they went up a dead-end alley with the MX and its extensive accessories (which fitted no other M-series body I believe). I have a K2 and I'd love to have a K2 DMD as well as a collector's piece.

In fact the MX was marketed as the Pentax professional system camera for years, prior to the debut of the LX.

Another difference previously unmentioned is the thickness of the camera body covers.
To reduce weight Pentax M-series top and bottom covers were made thinner than previous models.
Consequently the thinner metal is more prone to damage, i.e. dings and dents.
Normally these do not affect function.
