I have been seriously considering purchasing a Konvas 2m recently. However, I am also intriqued by the Arri 2c. The 2c is quite a bit more expensive, but I'm wondering if it would be a more trustworthy camera. I realize regular service plays a big part in dependability. I plan on having either camera I buy serviced regularly. But, do you think the 2m would be just as dependable as a 2c if it was serviced properly and well taken care of.
i think the arri is more reliable,easier to get bits for and has more options. its also not necessarily that expensive. ive had a few and sold them. they are actually dirt cheap or rather can be. id go with the arri.their quality is consistent,the eastern european stuff is not.

A Konvas 2M with an OCT-19 mount for Russian lenses, crystal sync motor, and a set of primes can be had for around $2000.
Differences between the two cameras:
The Konvas 2M already has a hard front, and can have the lens mount swapped for a PL version. The only thing that needs to be changed is the mount. An Arri 2 would require an entire new front end to replace the 3 lens turret, plus the PL mount.
The Konvas motor will do 8, 12, 16, 24, 25, and 32 fps, all crystal controlled. The Tobin on the Arri in this eBay auction will only do 12, 24 (sync), 25 (sync), and 30.
The Arri 2 does not have an orientable viewfinder. The Konvas does.
Swapping gates on the Konvas takes 2 seconds (i.e. Super 35), and can be done without tools. Here is a page I made showing all the Konvas gate options, plus photos of the ones I have access to and how they expose on film:
I challenge anyone to show me where I can get an Arri 2 with a crystal base and a set of primes for $2000.

I've suggested a vertical aperture size of 16.0mm (the same as academy) to Rafael. I think that's about as high as you're going to be able to go without encountering the shutter coverage problem shown on my site. This hasn't been tested, however. I'll have to wait for the new gate before doing tests (Rafael has promised me one). Once I have it, I will expose some film and post the results on my page.
BTW Thomas, Raf's new super 35 gates...do they not need any adjusting on a 2M?

The Konvas motor will do 8, 12, 16, 24, 25, and 32 fps, all crystal controlled.
Today, available modification of electrocal motors of Konvas cameras :
15EPSS, 17EP-16 APK, 18EP-16 APK, 19EP-16APK
on crystal sync multi speed version with 6, 10, 16 speeds :
6.25, 8, 12, 12.5, 15, 16, 16.6, 20, 24, 25, 30, 32, 33,3, 40, 48, 50 fps.
And other technical possiblities :
- 4 pin XLR cannon power connector,
- international glass fuses holder,
- Soft start and soft stoping of motor.
- Shutter Parking stops the camera each time in the viewing position.
- Manual adjust of phase of speed at run mode and manual turn of axis on low sped at stop mode.
- Wide system of sound information.
- Light signal of not crystal sync speed.
- digital voltmeter for show condition of battery ( +/- 0.1 v )

The bad things are that its optical system is dark, dark, dark (due to a pointless right angle prism) and that the engineering is sometimes a bit crude. On the other hand at least you can swing the viewfinder (although the image doesn't stay upright), something you can't do on an 2C. The mags are also a bit of a nightmare and can vary in take up tension and film transport quite considerably.
