Excuse me, but I'm new to posting in forums. I used to collect vintage cameras and lenses and still have a 35mm f3.5 Super Tak, a 50mm f1.4 SMC Tak, and an 85mm f1.8 SMC Tak together with a Spotmatic II from that time. Since buying a full-frame digital camera, a Sony Alpha a850, and discovering this thread (I'm a little more than half-way through it.) with all the wonderful photographs in it, I've purchased a couple of adapters and a few more lenses and hope that I might join in the exchange. I just started using the taks with my digital cameras a month and a half ago while vacationing in southern Colorado. The two pictures attached are from that trip taken with a 28mm f3.5 SMC Tak mounted on a Sony Alpha a55, so making the lens effectively 42mm. The camera's light meter works very well with the lenses, and I've recently discovered I can use Aperture Priority with them. The picture of the night sky is one of several taken with the camera on a tripod, the ISO set to 800, the aperture at f3.5 and the shutter at 5 seconds (the light meter's recommendation). With the darkness and an EVF viewfinder, all I could see in the viewfinder was noise. I couldn't even tell if my camera was in proper orientation to the horizon. All in all, I was impressed with the result. All the night photos were properly exposed. Fortunately, the a850 has an excellent OVF and that's the camera I'll be using in the future. Anyway, greetings to all, and I hope you'll let me join (overlooking the fact that I use Sony cameras and not Pentaxes).
