In Topic: So many quality Russian kits for sale...

The Konvas magazines are not difficult to load, you just have to be careful to maintain exactly correct loop sizes. 

 

the problem with the Konvas mags is that they are quite picky about correct maintenance and calibration (pp spring pressure etc) and there is some compatibility issues if you try to mix different generation mags. 

If you know what you buy it would not be a problem at all like with any equipment :) 

 

the easiest way to load the Konvas mags by my opinion: 

 

 

 

 

If you want a good old 35mm camera I recommend Cameflex! it is possible to get one in good condition, just make sure that it has NIKON MOUNT so that you can easily find good lenses for it :)

 KSR 2M in the ebay ad is just a copy of the Eclair Cameflex in a lot of ways. I know the movement isn't the same, but if you look at the two cameras side by side, you can see the Russians just copied it. The Cameflex was already a difficult camera to use, very loud, heavy and not well designed. I can't fathom how the Russian counterpart would be.

 

Konvas cameras are not exact copies of Cameflex. the early top latch model has similar type of magazine sprockets but for example the film path around the gate and the camera body and mag gears and mechanics are totally different. The actual movement is different as well in Konvas vs. Cameflex, there is nothing similar in them. (I have couple of Konvases AND a Cameflex so pretty easy to compare side by side :)  )

 

The turret design and oct18 lens mount is copied from a Arriflex (probably Arri2A) but Konvas was not the first model copying Arri and the "original Russian copy" model would be the AKS4 camera which resembles Arri2 very clearly. 

 

So the path probably was:  Russians first copied the Arri2 fully and when Cameflex came around they partially copied the quick magazine design to Konvas but kept the well-working Arri-style turret and designed a more simple and cheaper to manufacture movement by themselves.

ps. your 16mm Western manufactured camera kits seem to be pretty overprices. You should maybe get an Aaton LTR or Arri SR if wanting to spend thousands on a 16mm camera :)

 

 

I could sell you a SOMEWHAT working Kinor16 2m camera with 12-120 lens but it would need to be locally picked up from Finland because I need to show you what is done to it and how to get the motor back running WHEN it starts to run on wrong speed. 

It is a bolted-together diy camera project so if expecting to just get an easy and reliable 16mm camera for your shoots I would try some Western model :D 

 

Konvas is OK though if properly serviced and if you happen to get a good kit together. May take some year or two to accomplish. As said the Kinor 2m needs the crystal motor to really work. Don't buy the SP you won't get good lenses for it

russian gear is OK for any use as long as it is properly serviced. 

The service is the key here, these can be very picky cameras and they will ruin your shoot if they are not working correctly or if you don't know how to use them. 

They can be very handy and affordable if in great shape and properly serviced and adjusted regularly.

 

Cameras directly off of ebay don't work before they are put together by a technician. I have bought couple of Konvas cameras and they may even have gravel/small rocks inside them. the sellers know nothing about the cameras OR if they know they don't want to tell ...

 

Please notice that almost all of the Russian kits you linked are sold WITHOUT LENSES. 

Russian lenses are pretty affordable in general but they may be EXTREMELY DIFFICULT and time consuming to find in good shape and you will spend couple of times more to lenses than what the camera costs. 

Kinor sp lenses are relatively rare. Kinor 2m lenses too and you may need to purchase what you can no matter the shape they are. Wide angle Konvas lenses tend to be in very bad shape, especially oct18 ones. It took me 3 years to get a good condition 28mm F2 lens for it which is not scratched all over the elements. 

35mm lens is great and 50mm too. 75mm totally overpriced by hipsters and impossible to get for good price. 135 kinda cheap quality but ok but very affordable. 22mm vignetting a little and pretty rare. 18mm impossible to get in usable shape. for oct19 versions it is a bit easier but they are much more expensive. 

You really should concentrate on the lenses you want when purchasing a camera, especially if wanting a Russian kit. There is additional danger of accidentally purchasing AKS mount lenses when trying to find oct18 mount ones. the mount look pretty similar in pictures and the sellers may not know the difference but they are totally incompatible mount and cannot be used with Konvas at all.

 

Kinor cameras are great in other ways (except very difficult to find usable camera body and usable lenses) but the motors are their weak point. eBay motors may be in too bad shape to be used at all (burned down electronics because of wrong polarity "test runs" by sellers etc) and even working motors may be unreliable. 

I purchased 3 motors and got two bad ones and one which works SOMETIMES correctly and most of the time not. I strongly recommend building your own motor for it or ordering the Olex crystal motor which is much better construction anyway.

 

Russian gear can be affordable if you know what to look for and how to service them. You have to be very knowledgeable about the stuff though and you need to be patient to wait for the usable ones to pop up

I for example have an old Cameflex mains powered motor from the 40's which runs perfectly 25.00fps. it is actually possible to use an inverter to get 230v 50Hz input to it and thus get it running steadily at 25.00 fps with battery power
