I bought an old Brno ZKK 602 rifle in .375H&H and it came with a Zeiss ZF/4 scope (Jena made) in the old Brno mount. Scope is still clear and looks very usable, but I have no idea how to make adjustments with this scope. I've tried Google with no luck finding instructions. Anybody out there know how it works or where to find instructions?

Does this page correspond with your scope?

The scope you have is obviously the East German ZF4, commonly sold with Brno rifles before the Wall fell. If you delete the slash from your google searches, you might find out more.

I have looked through them but not owned one, but quite liked what I saw, in field blending at least.

They were reticle-movement, which means you have to mount it carefully to keep the post near the centre. This should not be difficult laterally, as the mounts have windage adjustments.

One of the turrets on top is the elevation knob, which may lack clicks; the other is the reticle focus.

You may know that the Russians looted the old Zeiss Jena factories c. 1945 after the Americans 'liberated' many of their top technicians, who then went and set up Zeiss Oberkochen near Munich. One engineer, a B. (for Bernhard?) Nickel, started his own scope factory at Marburg, not far from Zeiss's Hensoldt plant at Wetzlar.

Despite these setbacks, the DDR resurrected the optics business at Jena and had the hide to use the Zeiss name. The products may have been a bit old-fashioned but seem to have been reliable. Some of their ZF4 and ZF6 scopes seem to sell on ebay for as much as Western Zeiss models from the same period.

I hope it works for you.

Wink,

Did you check the page at the link I posted?

Wink,

I have a Zeiss Jena 6x42 I bought, circa 1982, in the old DDR (East Berlin) and is mounted on a Czech ZH 304 BBF.

If your scope has two turrets on top, the rear adjusts the focus and the front (objective) is for vertical adjustment. You can see the reticle move as you adjust it. The horizontal adjustment is via the mount - this can be a royal PIA to adjust accurately. Once adjusted it is not a problem.

My scope has served me well on my BBF and this combination of scope and BBF has taken game in Europe, the U.S., and Africa.

Hope this helps and Waidmannsheil,

Don

No, that scope is not identical to mine, but thanks for looking for me.

Don, I believe that I have that scope. I am a little concerned about the locking mechanism for both the front and rear turret, assuming the two indentations are there for that.

Wink,

The front turret is easy - flat blade screwdriver is all it takes. Hold the outer ring steady and loosen the slotted part - adjust for vertical and carefully re-tighten.

The focus knob (rear turret), on mine is snug but not loose, so I can't remember if I ever loosened it, but I can still adjust for focus. Plus with the two indentations, it can be hard to find a tools that fits.

The scope is tough, so I doubt you can do much damage, if you follow the above.

If you still are unsure, I can scan the original "instructions", in German, of course.

Hope this helps.

For Line: Grubscrews on mount.

For Focus: Rear milled disc.

For Elevation: Front milled disc locked by coin head screw. Do not remove or overtighten this screw it is for locking elevation when this has been selected. Movement is limited by internal stops.

That's what comes written on the box. Line is by the screws on the mount. Am not at home so can't give you the figures.

But, basically, treat the grunscrews as if they worked like the two big dome head screws on Redfield mounts. Screw in or out to move line left or right.

When you get the "feel" 1/4" left or right adjustments are achievable.

When I'm home next week I'll post how much of a turn moves the line. I think, not sure, 1/4 turn is 3" at 100 yards.
