Takumar 55/1.8: SMC and AUTO compared







SMC and AUTO Takumar 55mm f/1.8's compared. The SMC seems to have the front element recessed a bit more, you can also see how effective the SMC coating really is.
Note also how the aperture rings turn in opposite directions.

Photos taken with SMC Takumar 50/1.4

I just got one of these today. Great comparison photos. The Auto-Takumar has an interesting construction. Typical Asahi practice has the beveled trim "name" ring unscrew, revealing screws underneath that hold the filter ring on. On the Auto-Takumar, the "name" ring is threaded into the filter ring, but you don't need to remove it at all to access the front of the lens. The filter ring also is threaded. It simply unscrews, just like a filter. I've never seen that technique before. I don't remember ever taking apart a Super-Takumar, but definitely by the metal-focus-ring S-M-C Takumars, they used typical construction. The Auto-Takumar also has quite a lot of brass inside, which in later lenses is replaced by aluminum.
