Scarlet meets a Soviet legacy :)

This monster OPF 25-250 (50-500 with anamorphic rear module) in OCT-19 mount ("CKBK" made, now "Elite Optics") appears very impressive lens.
Need back focus correction - now searching for technical docs.

 
HAh !!

Nice lens I was wondering about those big lomo's......are they sharp? Do you get consistent exposure & focus across the zoom range. Also do you need a forklift to mount the lens ; )

Not sure where you live but obviously the magnification works really well when zoomed in because Red Square looks like it's just right outside your window. !

Does it cover 5K?

My 20-120 (40-240 ana) portholes - it's good for 4K, so wondering on this one :)
 
Wonder what its images look like to :)
 
I own this lens as well, bought it from Ebay US 5 years ago with the anamorphic rear. Looks like it was in a very good condition. I found a PL mount later to find out that the backfocus was dramatically off. My lens tech spent a long time to get it kind of OK, but he was never able to get the anamorpic rear to work . Had gears installed and a support (it is very heavy). Optically it is very poor, mecahnically very weak. One of my biggest wastes of money. It looks very cool though, big peace of glass, strange cardboard front cap. I keep it as a paperweight, totally unusable for professional work. It might be my copy, but I doubt it....
 
Just out of curiosity, who is your Lens tech? I have two 25-80's and I have seen lots of good footage from the 20-100. I would be surprised if the 25-250 was Completely unusable. Hell even the foton can make some nice pictures under the right conditions.
 
Nick, you might be right, but this lens tech had 40+ years experience before he retired a couple years back. He told me mechanically it is so weak that you should not transport this lens top down. The focus is very uneven over a flat image. Most of the time you have to rotate one of the optical parts to get it right. He could not apparrantly. I migth bring it to Truelens services from the UK when they are in Amsterdam at IBCT. They might have a look at it, maybe it is worth to spend a couple of hundreds more on it.
 
Everyone seems to agree when mounted they look good ...... BUT are the Lomo zoom lenses worth it ?

From what Mick is implying, optically no they are not...... but that's the 25 to 250. Is it just this Lens group?

Nick, Lomo guru ; ) have you got good results out of the other Lomo zooms or are we just better sticking with the primes? Less mechanics, fixed glass , less stuff to go wrong...?
 
Is it my imagination or are those rods actually bending...?

I have limited experience with the zooms. I own two Ekran 25-80s, both from 1991. They are excellent. The mechanics once cleaned and adjusted by Duclos are fine. No issues. I have seen a lot of footage from the 20-120 and it has looked very good. I owned two of those briefly. One I sold before I ever shot anything on it, the other one I took apart. The one I took apart was well made with the soviet equivalent of teflon bearings, and it was a fairly modern design. The original lens was designed and built very well, but there were several places where you could tell that someone repaired it with not factory parts, and didn't do the best job. I suspect that the biggest factor affecting the lomo zooms is who serviced them and how they did it. For example, on the lens I took apart there were very nice little roller bearing assemblies that rode in machined tracks to support the zoom elements. One of them was missing and had been replaced by a poorly fitted brass bushing. That's the kind of thing that will fuck them up. I have never seen the 25-250 in the flesh, but the general impression I get is that it was not as nice as the 20-120. But all that being said, I have seen really lovely footage from the old Foton 37-140 lenses as well. I have one of those with the ananmorphic front, but I am waiting for my PL mount in the mail.
