"Micro prestige"
Micro refers to the company which produced fine mechanics and certainly not to the shape of this huge press camera.
"Micro Prestige" is the headline of an article in the Amateur Photographer edition September 1956 and the article continued with
"few 5x4 cameras are held in higher regard by professional users than the Micro-Press."
And yes, its huge impressing performance and beautiful design combined with lots of essential features makes it a
dream for the real press photographer. I herewith present a nearer look at this British competitor of the
US Graflex.
As said before the MPP Micropress is far from micro as its name might suggest. In the contrary, it is a huge 4x5 format film camera with on top a huge build in rangefinder. You'll see immediately some family traits pointing in the direction of the US Graflex family and yes 80 percent of its design comes from the Pacemaker Speed Graphic which needs no further introduction. There are however some interesting details which never the less are very important. The drop bed has another construction as well as the bed brackets. The rangefinder is of a completely new design. Further more the lens standard slider and the track yoke differs from the Speed Graphic which makes that both are not interchangeable with the Graflex parts. The focal plane shutter seems to be the same, but closer examination learns that there are huge differences.

At the first glance the M.P.P is a look alike of the Pacemaker Speed Graphic. However there are some details that asks for a nearer look. The first striking difference is the integrated rangefinder. Unlike the Pacemaker Graflex top mounted rangefinder, the M.P.P. Micropress rangefinder is an integral part of the camera body and gives the camera the unique and striking design, undoubtedly the touch-of-the-fifties. The weight is at least as touching as the design and the camera-man should have the strength of a boxer to carry the huge camera with a weight of more than 5 kg which includes the flash plus the 6 sheet Grafmatic holder. Carrying is one thing but holding the camera in front of your face when focusing is another thing. The open frame-finder should not be relied upon to give the exact coverage of a subject, as the area seen through the viewfinder will vary considerably from person to person and is greatly affected if the operator is wearing spectacles. By the way, focussing can only be done using the standard frame finder. Both windows on top of the camera suggesting being an optical viewfinder or at least a part of it, are serving as a rangefinder. The integrated rangefinder is coupled to the track with the lens standard. Interchangeable cams make it possible to change lenses.

Having said that it is about time to mention the positive side of this camera. Reason to take the M.P.P Micro-Press in the hand and to open it and take a closer look. The first thing we'll see are the brackets holding the drop bed. These are very nice made and much better than the Graflex brackets. The eye catching top rangefinder asks for attention. Comparing the to the top mounted Graflex viewfinder it is a relative easy design and construction. The optical image and contrast as well as the working of the mechanical coupling to the focusing rail are perfect.  At the first glance all other components look the same as the Pacemaker Graflex camera. The lens-standard including its frame-finder and lensboard-lock-sliders, the yoke between the drop bed guides, the infinity stops, the build in release knob, the front shutter release mechanic with its Bowden cable and last but not least, the bellows.

Non interchangeable parts!

In fact I'm sure originally these are fundamentally the same components, but they won't fit, they are not interchangeable with the Graflex camera! The lens standard does match the Graflex yoke, the yoke doesn't fit to the Graflex drop bed guides and the shutter release mechanic won't match the lens standard. The Graflex guide blocs would not fit to the Micropress drop bed and the Graflex drop bed not to the Micropress camera. Perhaps nice to know which Graflex part does match the Micropress. Well that would be the build in release knob and the knurled wheels of the lens standard. I'm pretty sure they used 80 percent of all the original Graflex parts but made minor modifications. For what reason? It might have something to do with the UK post war financial situation, or to prevent re-import from UK to USA, or the bad economic situation in UK in those years. It would be nice to find out the real reason about all this. In the appendix you'll find the interchangeable and non-interchangeable parts with the Graflex camera.

It's about time to get an idea of the inner of the Micropress camera and we'll start right on the front with the rangefinder. Integrated in the camera body, the prism and beam splitter located behind both windows are  connected by a fine mechanic steering mechanism to the plunger next the exchangeable cam in the back rack. Turning the focusing knobs make the beam splitter rotate around its axle and projects the image on the prism. The photographer's eye will see two images drifting together and coinside to one single image as soon as the real distance to the subject has been focused. None of these optic components matches with any Kalart or Graflex parts. Note the simple but efficient construction using a tooth gear to couple the moveable cam with the right mirror.  The left mirror is a so called beam splitter. The left "port" receives the image of the right mirror as well as the image strait forward and reflects half of the mirror image while the other half stays transparent. 



The movement of the Rangefinder is actuated by a cam which is located on the focusing track back rack. The cam is fitted with dowel holes and is secured with only one screw so that it is readily detachable. The cams are engraved with the serial number of the lens with which they are associated. By these easily interchangeable cams the rangefinder may be coupled to an infinite number of lenses. This cam actuates a gear which is connected by a shaft that makes the mirror rotating when focussing.
Minor differences between both cameras such as the infinity stops and the higher positioned lens standard brackets (photos 3 and 4 ) make it impossible to exchange parts from Graflex to M.P.P. or the other way around.

Next secret to be solved would be the shutter mechanism. The Focal Plane shutter is expected to be the same as the Graflex shutter as it has the same 4 slits which are visible from the outside when the ground glass back has been removed. Winding the shutter is the same procedure as winding the Graflex and the setting for front and rear shutter is also the same as Graflex. The M.P.P shutter selector slide works exact the same as the Graflex but inside you'll find different parts. The release mechanics are the same as the Graflex parts, but they can't be interchanged due to minor differences. Finally the wooden dark box. Almost every part seems to be interchangeable. I must admit I didn't check that up till now.

Now we reach the elementary part of the rear shutter. The focal plane shutter has two rollers. The one in the upper compartment has a build in mechanic safety break to prevent winding the curtain further than its length and thus the risk of tearing it off from the roller. The roller has a square shaft end fitting into the bushing with a square hole. Inside the roller there is a shaft with a thread and bolt. Winding the key the roller thread moves the bolt to the end of a 2 inch long gap. Once the bolt reaches the end of the gap, the curtain will be on the end of its travel along the film back. Hence the winding can not be proceeded the fabric can not be torn off the roller. Great invention!



The track and front standard look very much like the Graflex  Pacemaker Crown or Speed camera.  Most of the M.P.P components are almost the same as used in the Speed Graphic although not too many of them can be mutually exchanged. The lens standard is almost 100 percent the same but has a different slider which is a bit thicker than the one of the Graflex and thus wont fit on the track. Upper and lower roller are different and not interchangeable. Track, back with ground glass, bed-brackets, drop base board, housing including build in rangefinder. All together it is easier to list the compatible parts such as the bellows, the build in release knob and its build in mechanism, the release arm and lens board. Tilt, slide and rising front nuts are exactly the same as the Graflex ones. The camera back is equiped with a focusing panel which accepts film holders with the raised lock rib trap. The springs are a bit different, but the working of the back is exactly the same. The spring loaded focusing panel frame pulls back to accept the Graphic type 5, Rightway, Lisco Regal II and other compatible 4x5 holders as well as the Graphic Grafmatic film holder. A closer inspection of the camera shows the winding mechanism on the right side of the camera. The position and the working of the winding key, the slide shutter selector, flash bi-post, shutter speed control, the shutter speed window and lever at the bottom of the plate cover are exactly like the Pacemaker Speed Graphic camera. However the winding key itself is not interchangeable with the Graflex camera. Also the mechanics inside have minor divergences and are not interchangeable.


Cleaning is essential for the good working.

After a long period of time and depending on bad storage conditions, the mechanic parts inside should be cleaned thoroughly from dirt and old grease to prevent malfunction and slow shutter speeds.
Focusing bed, track, guides and yoke need some care after half a century, while the curtain should be checked for light-leaks and rollers including the inside springs should be cleaned to new condition before renewing or replacing the curtain.
Without this maintenance the camera would be not reliable and thus worthless for photographing. Also lens and front shutter need attention and adjusting.
