  1. Everything is excellent for now, but, well, I asked myself:

    I will spend a good money for a near perfect Super 8 camera, then I've got very good results, and the director will tell me they are so crisp, you told me Super 8 look! This is not the look we are used to have from home movies. Then he will manipulate it with the silly effects, including defocusing, scratching, noise, unsteady pictures in editing, so what? I will have a camera I love with enthusiasm.

    Then for documentaries and feature projects? I am pretty sure they will call me crazy :) Come on, we are looking for the highest resolution ever created, and you are telling us a narrow gauge format. Do not dream so much, man!

    This is not a wild statement, but true for me...

    Despite for these I'll try to do my best for the newborn cameras!

  2. Considering the OT Logmar it makes one wonder why it doesn't expose a dot at the side of the frame like the MEKEL SP does? This would make teleciné so much easier.

    It would require very little hardware since the camera is already so very much electronic and digital. And putting it in when building from scrap is really a minor thing?

     

    I agree with Andries totally!

     

    The price will be around 2500Euros as far as I remember.

     

    I want to start a wave in Turkey possibly in Music Videos. In the past very few were tried, but never got so popular. I'll try to convince some rental houses already spend a lot of bucks for the camera equipment they rent. By the way, I guess that individuals will not spend money for individual purchases...

  3.  

    No doubt my one complaint about the R10 is the fixed hand grips and stupid battery holder. So many people lost the battery holder over the years. Lots of perfectly fine R10's ended up thrown away because the holder was gone and the owners decided not to sell the camera itself thinking it was useless. :(

     

    Matt, I did not give the battery holder when I sold my disassembled R8 I told before, because its exactly the same with the R10's. Recently, I did a bench running for all my stuff (regularly I do). I have seen that the camera is not working. Then I replaced the holder, and it worked. I cleaned the contacts of the problematic one, now it seems to be OK, too. Probably a corrosion causes this despite I never leave batteries.

     

    The replaceable battery holders help a lot when a battery leakage arises.

  4. When you run the camera very first time after you've dropped the film in, lateral guides and claw engage film in seconds. That's why it is recommended to rotate the cartridge's take-up spindle forward direction until it stops prior to drop in.

  5. And the Matt's film comes to the end with many applauses!

     

    Long live Matt!

     

    I wish Nikon would release more cameras in that line or further models like having the Beaulieu and Leicina's latest features. Unfortunately they have stopped making the movie cameras. The R series made for serious amateur filmakers in mind that time. I wish I could have a Nikon R1X (there is no such model) with a folding handgrip and changeable lens system like ZC1000 has...

     

    But humans were wishing to carry lightweight items beginning at the middle of 80s, that's why Canon replied with those plastics... Of course, Canon has tanks as well... :)

  6. Not sure what "4-year obsessive study with the highly skilled engineers" he is referring to..?

     

    It took 4 years to release the R8/10.

     

    Japanese have the Monozukuri (to make the things well). We see that not only in cameras, and in the 70s... :)

     

    I had shot some with my R8 in Bangkok during the humid season several years ago, the images were so sharp. Of course, Nikon tends to make more contrast lenses...

  7. These are the applied adjustment tolerances from the maintenance book for R10 R8. These form no information in itself about the the design or functioning.

     

    What do you mean Andries? Everything should have tolerances... This means a lot about the the design or functioning!

  8. There are two stop pins. One in use forward and the other for reverse. Easy to feel and see when you move the REW/FOR switch. The one stop pin comes up the other retracts. And reverse of course.

     

    Very very few people actually have an idea how these R10 stop pins work.

     

    I have looked at my R10, and its service manual, you are absolutely right! One for REW one for FWD.

     

    Their system is a basic switch principle. The ratchets are so designed for the direction. But I think they should be not understand as the registration pins, probably for correct film positioning in the gate...

  9. I had a Nikon R8 with the unimportant fungus on its lens, that I sold some years ago, after I disassembled completely. The buyer from Turkey paid me for that carcass USD50! :) What a name and model!

     

    We have seen the curved gates for mainly larger film formats, even in projectors. This is due to the larger in size films' area and prone to the curls to obtain more precise focusing and avoid the breathing of focus (this term also applies in the lens designs, but different).

     

    During the Nikon's design there was acetate based films too. They are not new... Super 8 doesn't need any curved gate.

  10. To be discussed the engineering specifics one should have an education of 4 or 5 years in the mechanical engineering degree, plus 2 or 3 years in the precision engineering, as well as having the advanced optical, electromechanical and electrical courses.

     

    But in the history we faced with the skilled and experienced technicians working with those engineers...

  11. The venerable Nikon R series, I loved the most, have those parameters (after a 4-year obsessive study with the highly skilled engineer and design team):

     

    Take-up torque - 45 ~ 60g/cm

    Film gate - 8,02mm in width, there should be a clearance on the upper side pressure plate.

    Side pressure - Upper side: 60 ~ 75g, Lower side: 40 ~ 55g

    Contact pressure of claw cam - 20 ~ 30g

    Protrusion of claw - 0,28 ±0,05mm from the base surface of aperture plate

    Moving of picture - Within 0,02mm vertically and laterally on the film plane, No remarkable periodicity is permitted. Fluctuation of the focused plane: within 0,025mm

    Displacement of picture frame center and of optical axis - within 0,1mm

    Position of picture area on the film - Displacement of effective picture area from film perforations: within 0,13mm, Difference of picture plane in the reversal run from that in the normal run: within 0,2mm

    Inclination of picture frame - With respect to the guide edge of film, Horizontal 90° ±½°, Vertical 90° ±½°

     

    Can you find these in the standards? Those are the just the small amount of information...

     

    This is the engineering involved in mathematics, extensive testing and a real know-how! Plus the high precision manufacturing...

  12. Also the the R10 stop-pin makes sure the film is not yanked past the gate too easily when the shutter is open. This way the R10 out classes all others. Nikon engineers had a good grasp of the features of the S8 cartridges and way of working.

     

    Noo, the stop pin is just for the reverse shot for accurate framing! During forward it has no effect!!! You have to examine it with a clear film like a leader...

    Also, the frame size is a little different than most cameras have.

  13. Tom, I should ask Juergen... Give me some time. He knows many engineers and designers, esp. in the amateur market.

     

    The venerable John (Mr. John Pytlak of Eastman Kodak, Rochester, NY, deceased unfortunately) would be the best person for the questions about the design... I missed him so much!

     

    Unfortunately, some of engineers I know in the former Soviet Union work in serious military projects and don't prefer to exchange mails with me anymore... :( Some doesn't speak English and German, also my Russian is not so good to discuss the detailed subjects...

  14. By the way, I examined the Super 8 cartridge just now again :), and I noticed that the loop forming before the film enters to the gate is not so much, so too much pressure might be problematic, due to the intermittent stress applied to the film on the gate, that's why the design might be made simpler by Kodak engineers...

  15. Anthony, you don't need to watch the movie to try to understand whether there is image unsteadiness or not. One frame with less blur captured will tell you so so. But you know that's not the correct way, because the steadiness has an amount to be measured. Films should be studied with a microscope with the naked eye when needed. The better way is to shoot the steadiness test patterns with the double exposure.

     

    Also, never trust on the video transfer other than prismatic flying spot one, 'cause the projector plays a role here too. The projector should have the sprockets, and checked with the test films such as a SMPTE film.

     

    I am sure you know all this, you are a working professional.

     

    Heikki, never compare the reversal stock with the negative. Reversal is a difficult stock to work with, with limited exposure latitude, and contrary to the negative characteristic curve its tend to be contrasty. I see that your film's colors are saturated.

  16. Look at Jose's work. It's the sharpest you can have in this format. If this is not enough for you, the only solution is to have more resolution or a better lens. Or, shortly, going to 16 or even 35mm.

     

    This is very easy, Tom.

     

    Lets wait for the camera is released, then compare the images shot with the same camera Jose used with the Logmar camera, the lens should be the same for a fair compare. The steadiness test should be also done!

     

    It could be better than words, because if the results are better with the Logmar camera, then you are in trouble buddy! :)

     

    By the way, please don't underestimate the Super 8 cartridge pad gram force applying several points on film...

  17. But what you said is interesting... are you really in touch with former Soviet technicians ? I would so much love to learn from their experience. If they could make something like a Zenit Quartz but with oscillating mirror and functional C-mount that would be something to throw my money in !

     

    Yeap, they had visited me in 90s in Istanbul when they were active at the factories. Some from the Krasnogorsky Mikhanicesky Zavod (ZENIT) and Odessky Zavod "Kinap" (was the largest projector manufacturer in the USSR) were here. They have graduated from the LIKI (old name: Leningrad Institute of Cinema Engineers).

     

    Also, I have visited the LOMO factory in 2001 in St. Petersburg. I have visited my friends at the NIKFI (a large institution and experimental works - Scientific Cine-Photo Research Institute) in 2010 in Moscow.

     

    Once I was in contact with all manufacturers in the field worldwide. Crazy, huh, but real!
