After owning the lens for 2 years, I recently picked up a nice Speed Graphic to go with it.

My Aero Ektar still has a seized cylindrical section that needs to be removed to allow the rear of the lens to go through the opening of the front standard.

In the meantime, I've made a 3D ptinted lens board that will hold the lens further forward, so at least it's usable. However, there is more stress being placed upon the front standard than I'd like plus it makes the set up even more front heavy than it will be when the lens eventually sits in it's optimal position.

Looking forward to using it!

Legendary aero ektar. Is possible to focus with this unedited version? Would be interested in some samples then.

Meanwhile saw one Navitar 177,8mm f2.5 which should cover large format but it has also some rear part to dismantle. By the specs what I got from seller it is too long even for middleformat SLR by my opinion. Might be good for Graflex. But not sure.

Having the lens sit further forward is not a problem with infinity and effectively makes closer focussing easier as it requires less bellows extension.

I did not know that Navitar made lenses for formats greater than 35mm. Ideally you want the rear of the lens to have a diameter of less than 74mm for a Speed Graphic, the cylindrical piece on the back of my lens is fractionally wider...

Yes also for large format. Didn´t see proves/pictures made with such combo although, hah. Only mounted on LF cam. That Navirar what I have talked about has little smaller back hole. But I do not solve that then. See to much complication about adapting for some midformat cam or for acquiring new Graflex. You know.

If you're worried about the front standard, put a support ("crutch") between the lens and the outer bed rail.

I shoot a 2x3 Pacemaker Speed Graphic with a 4"/2.0 TTH Anastigmat (ex-Vinten F.95) mounted completely in front of the lens board. Same problem, same solution.
