Pentax MX Film SLR - that VF was a huge surprise

From what I have seen, I believe the Pentax MX has the biggest viewfinder magnification of any non-interchangeable viewfinder SLR cameras. Of course this dates back to the original Asahi Pentax that had a lifesize viewfinder and I appreciate that Pentax continued this practice as opposed to the other brands.

Pentax LX ASA Dial

Just to be sure, in order to move the compensation dial off the center (1X) position, you have to press the DIAL LOCK RELEASE BUTTON as shown in the Pentax LX manual. With that button depressed, you can move the compensation to 1/4X or 4X position.

There are exceptions to this. If you have the ASA set to the lowest setting of 6, you cannot move the compensation to 4X but you can move it to 1/4X. If the ASA is set to the highest at 3200, you cannot move the compensation to 1/4X but you can move it to 4X.

Pentax LX metering problem?

Correct, the meter LEDs are always active regardless of whether or not the film has been advanced, in manual or aperture priority mode, even in bulb setting.

Unfortunately, there is no Pentax replacement for a Minolta X-700. For that matter, there is no other name brand replacement for the X-700.

There was only one Camera of the Year that year . . .


I am not certain any others had full IR remote control facility . . .


I am also not aware of any - even modern AF types, that have a full intervalometer back . . .


Besides, Minolta lenses and accessories are bountiful and relatively inexpensive. Who's idea was it to replace the X-700 anyway . . . ;)

I am not aware of any camera that is programmed with each film's reciprocity characteristics based on various lighting conditions at various exposure times - let alone the exposure times I use. Neither Kodak nor Fuji specifies this in their spec sheets and just state to try it yourself.
I have personally tried some Kodak and Fuji color negatives as well as to a limited degree Kodak TMAX100 and Fuji RVP. Sorry but have never used Acros.

The Pentax LX is the only camera ever - past or present, that can aperture priority autoexpose a scene for as long as it takes, all the while monitoring the scene and adjusting accordingly. I've tested all the films I use for many hours long under many lighting conditions. If additional time is needed, the LX exposure compensation can he used.

Kodak and Fuji do not document reciprocity anywhere near what I use but they do encourage you to test it yourself.

As far as I know, there is no digicam that can get anywhere near this except perhaps those used in space . . . :cool:

Check out the full res version of the comparison image I posted above with a particularly scratched up Kodak 160VC courtesy of Fuji professional lab.
Here is another this time of Kodachrome. Nikonscan ICE is the only one you can use with this film type with the Coolscan 9000 being the best.


Full res version -> Kodachrome D800-Coolscan

Canon's Canoscan makes a complete mess of Kodachrome while Epson's is better but still problematic especially between the dark and light areas.


Full res version -> Kodak K64-029 ICE

For me personally I find film's outstanding latitude - particularly as it applies to highlights/resistance to blowing out, to be a great advantage.



I have tested more current digitals then what is shown and this has not changed much so I haven't updated the comparison.

Also for me personally, I like taking night shots at very long exposures. Clearly the Pentax LX has no equal when it comes to this, and so this is another reason I still shoot film. This one using the LX on aperture priority for about 45minutes on Kodak Ektar 100.



BTW, this is not to suggest that I don't have and use a substantial number of digitals. In fact I am currently enthralled with an FPV setup on my RC truck using a 0.0001Lux starlight microcam.

I really enjoy all manners of imaging . . . :D

Of course no ICE with any DSLR scanning. Depending on the condition of the film, this can take far more post work then scanning and even then it cannot compare to Nikonscan ICE.

I have the FF bellows setup with the film copy adapters so digitizing is simple and quick as it applies to b&w and color slides. For color negatives, post processing can take far longer then the 50 seconds it takes for my Coolscan to scan a frame and apply ICE.

Correct - with everything else equal, film resolution scales proportionately with surface area.

I've quantified what 4000dpi scans from a Coolscan compared to DSLR scans of 35mm Kodak Techpan film as shown below.


Full res version -> Kodak Techpan 04-27 scan compare

Although there are more pixels in a Nikon D800 file they are about equivalent in actual detail resolved compared to the Coolscan at 4000dpi.

I'll be testing the D850 to see if that is better in resolving detail but I am more interested to see how the built-in color negative conversion works as I've found the results from Nikonscan to be the best. But of course there is no ICE in DSLR scanning and Nikonscan ICE is just magical in this respect.


Kodak 160VC-06-36 K20D vs 9K ICE

As far as resolution is concerned that is dependent on the DSLR used too . . . ;)

---------- Post added 01-13-19 at 03:37 PM ----------



Of course there are many drum scanners out there. I have been meaning to try out a 10,000dpi Heidelberg Tango just to see if it can finally resolve all the detail in my 35mm frame of Kodak Techpan . . . ;)

The LX took no design queues from the K2 as the latter used a vertical shutter, did not have interchangeable screens or backs, motor drive only with the K2 DMD and viewfinder metering. And unlike the LX, OM2&4, it cannot meter very long aperture priority shots.

Like the MX is to the OM-1, the Pentax LX also borrowed a few technical points from the OM-2 and greatly enhanced them such as off the film meter, TTL flash gigantic viewfinder and of course physical size - with full interchangeable viewfinder!



As far as I can tell, the OM2 was the first production implementation of off the film metering although prior patents indicate Canon and Minolta experimented with it. The OM2 implementation required two metering methods with a cel in the mirror box for auto mode and cels in the viewfinder for manual mode while the LX used a lone cel in the mirror box for both. Later on Olympus used only one cel in the mirror box for all metering in their OM3&4 models.

The LX uses horizontal shutters like the whole OM single digit series except that it is a titanium foil.

The OM2&4 can reliably aperture priority autoexpose for minutes while the LX greatly extended this capability by being the only camera ever - past or present, that can do so for as long as it takes.

Of course this site is good but there is also https://www.photo.net/discuss/forums/olympus.1902/

I have a good appreciation of Olympus cameras as I am not sure if Pentax would have given us the MX and LX without the OM series.

That's correct, it requires batteries to operate on aperture mode or speeds under sync (X). Of course the B (bulb) setting is also mechanical and doesn't require batteries to operate.

Welcome aboard!

Thanks for the heads up but it does sound too good to be true especially since they use magical and foolproof in the description . . . ;)

However, if it works then it seems worthwhile trying it.

Seems as good a plan as any although b&w processing is really simple once you get the first roll done.

That's a great opportunity worth taking advantage of!

Last class I took, I involved myself with the rest of the class projects even though I really only wanted to use the facilities more. Got to try various papers and other developers too. Turned out to be a lot more fun engaging with others of similar interests - hipsters and old alike!
