Thanks Rob, but the FM3a was a "must-have" and I took it "as-is". I don't really care about the shutter noise, but I'll try your experiment to see where is effectively the noisy part. Its strange sound was just a fun note I discovered while comparing it with the other SLRs I have. I mean every time each of us purchases something, the first thing he does is comparing it with what he already has, right? I won't change the FM3a because it's noisy, in the end I'm satisfied with it. I knew it would have been noisier than other cameras but I had kind of "crush" for it, you see what I mean?
Then, here is a little ( and funny ) update.
Today I managed to take the FM3a with me at mass and as usual I took a few shots of the ceremony. The 50 was on it, waiting to couple with the 40 Voigtlander (I'll explain later why). At the end of the mass, the priest told us that there were a bunch of boys (and girls, of course) coming from Africa (not sure which part, maybe from southern Morocco?) who are here for two months and its their first experience out of their country.
So I took the opportunity and went to visit them. I proposed them and their escort to take some pictures of them and since I'm known there they accepted. Of course I'll have to give them the prints once I have them. By the way, I was shooting with a T-max 400 stretched to 1600 (good in church but also there because I want to practise with depth of field and manual focusing) so that I worked most of the time around F/11 and 1/2000s or so.
Well, the "unexpected" (now is a learned lesson) came when I shot the first picture. ALL (and when I say ALL I mean ALL) the twelve kids came around me and grabbed and touched the camera trying to look the picture just taken. I tried to tell them it was not digital but I doubt they have understood my words. Their escorts speak Italian (very few), French (a bit more) and Spanish, but they are honestly too little to speak any other than their native language, whatever it is. However they were really craving to look and touch and handle the camera: fortunately it is in metal and the only (apparent) thing I got was some fingerprints in front of the 50mm (I'd say really the LEAST) then they wanted to shoot themselves. I was at the end of the roll and they sneaked a few pictures of it (I guess the photographer will wonder when will look at the latest pictures on my roll 😀 ) Then I finally removed the roll and set the camera to 1/4000s just to make them able to shoot again as they wanted. I even had the possibility to "teach" them something about shooting "Look at me, I said: CARICA (wind) and SCATTA (shoot), CARICA and SCATTA" Most of them understood and they were all boys. Of course they shooted without caring anything about if it was in focus or not (plus that there was not the film roll) When a little girl came a bit shy I tried too to show her how it was easy but she didn't understood correctly and kept the lever opened so that she couldn't shoot. Since the other boys were pressing again to shoot, she tried but didnt do that. What a pity. Among all them only about her I really cared.
However, I have to say that it will be for sure my camera if I ever go somewhere abroad where I can meet such boys... Can you imagine so many boys handling TOGETHER (!) the much more expensive F6 or D700 ??? Kind of a nightmare 😉 You should have had to see how quickly (and without any respect for the lever) they winded the shutter, still it resisted. What a baptism of fire!!!
