A-50mm 1.7 vs M-50mm 1.7

From my old film days I would think the 1.4 might be have an edge based on speed and sharpness (even if you have to stop down 1 you have the edge) but for price and general use, I really think my first purchase choice will be an M 50mm 1.7 (rather than the "A" after all this discussion. It's said that there is a learning curve with the buying of lenses. Use one...if you like the results, stick with it. If there are constant issues that bother you, change it for one that corrects that issue. Personally if I were you I'd keep the 1.4 for sure!

BTW...I also LOVE the quality of construction of the "M" over the "A" and I think to me that makes a real difference. TMHO!

Not sure yet as it has been MANY years since I used such a lens, however, I have read (and someone can correct me if mistaken) that the 1.7 gets better results when stopped down to 2.8. Reading posts in the Pentax lens forum reviews there is a definite "quality" distinction with the 1.7 in that many more users have regarded it as superior. I suppose it all depends on the user, the light available and the shot you need!! Since maost of my work will be without flash... I am still tilting to the M 1.7 version and pick up an "A" for flash use. We'll See...

The trigger voltage I found was from Powershot Posts which seems to mention a lot of these older flash units. Will see if there is any other referrence before going there!

Just found an old posting in 2005 that someone tested with a mutimeter and found it to be 11 volts on this model. Looks like it's good to go!!

I have in my old collection a Starblitz 5000 that seems to only need some corrosion removed from the base locking clip. I am in the process of cleaning it up and see if it still works. With manual power adjustment and double flash it should be a great unit....once again!!

OK, now this is making sense! Looks like the A is my choice - did not know you could disable "A". Also, on the flash issue, I have been considering the Vivitar 383 for this setup - any thoughts from you or Elliott? Thanks for this input!

Thanks Elliott - I also read an issue with the M when trying to fire a secondary flash. I suppose the A handles that without problems also. I really prefer old school manual and it looks like it can be done with the "green" button.

Looking for some input here, and trying to fill a gap in my lenses for K5 startup. Anyone have an idea what is best in the SMC 50mm collections? I read the reviews and looks to me like the edge goes to the M series but would invite experiences. Thanks!
