I just got the negs & contact sheets back from the test shots I ran 1 1/2 weeks ago with 6 old Kodak No. 2 Brownies. 4 of the camera gave nice results, very predictable with each of the 3 built in "waterhouse" stops and different light conditions that I shot. The other two had sluggish shutters which gave unpredictable results, so I need to work on them.
Overall, however, I was surprised at how well those old 80 - 100 year old meniscus lens box cameras performed. Now, armed with individualized data on each, I can enjoy shooting them now and then when the urge strikes.
