I have the Argoflex 40 model and while being bare-bones, it does rather well.. It has the 75mm f4.5 focusing coated Vaskar lens. Several years ago I was testing two Rolleiflex cameras out that I had just purchased and tuned up. I had never shot a roll of film in the Argoflex and thought it a good time to run it through the same test as the Rollei's. I respooled a roll of 120 onto are spare 620 spool since a 120 spool was just to tight to feed right. To make a short story shorter the Argoflex did extremely well. It's contrast at wide open f4.5 was less than the f3.5 Planar and f2.8 Xenotar I was testing as was the sharpness/resolution, but stopping down to f8-11 was a whole different ballgame. I would have no problem using the camera if I had to, but since I have many better cameras I don't have to. So, it's on my shelf with it's original box, flash with box and instruction manual. One thing these cameras have is very bright viewfinders and there is no problem viewing in any light condition. Of course scale focusing might be a problem for some folks. I have no problem scale focusing and can estimate distance very well. All said, the Argus Argoflex cameras don't have all the bells and whistles of a Rollei, Yashica 124G, but you might be surprised as at the result you can get if you take your time and use your head. Try it!
