I'm curious as to what you're shooting that requires a camera with virtually no shutter lag?
If you're focusing your attention on the delay in your camera you're not concentrating on your subject enough. I've shot with a lot of different cameras in my career and never shot one that was so noticeably slow that it distracted from my shooting or drew my attention from the photo making process. But then again I'm a guy that shot college football from the sidelines in the 60's with an M body, visoflex 2 and long preset lenses.
THANK YOU EVERYBODY FOR YOUR INSIGHTS AND OPINIONS. It is of great help to me.
I always shoot people and try to shoot mostly on my feeling and spontaneous. Kind of street shoot style and enjoy the Leica M system very much. Lately i had some mishaps with composition of horizontal shots/portraits. Maybe cause of the combined shooting (M9/M8.2) so especially on Fim (where you can't chimp) I would like to see the image more reliable.
But i know i will always want to act on impuls and want to be able to get that moment. AND it is quit possible that shutter lag will not be a big problem but it is just something that is in my head. I want to 'feel' the shot/trigger and time when it goes of. I sold my Sony A7 cause i didn't feel the shutter and was happy with the responsiveness of the Nikon D700 after that.
Some times i focus and frame and wait for that moment on portraits for instance. I want the shutter to click as soon as i push the button. Or at least not have the feeling that there is lag.
Now i spoke with a Dutch repair guy and he said that the R6 has a kind of tube/valve that dampens the mirror. When that is oily it prevents air to come out of the valve/tube and it slows the momentum. That sounds logical. So than the question is if the R6 is fast enough (for my feeling) when i have one in serviced condition. And how is even the best serviced R6 in comparison to FM3a/FM2.
From all the reactions it seems that the Nikons are quicker by design. To bad i still did not manage to handle a r6 in the flesh to see how it feels. If the lag is that bad as the R4 i tried or maybe it is ok. Or that the feel of that camera is so nice that think i want to try it anyway.
For now i have black r6 that i can order for 380 euro. A 60mm lens (My first R lens) will cost app 350 euro. Or i can get a really nice black FM3a for 450 euro. That FM3a can work with the 17mm ais, 28mm 2.8 ais, 35mm f2 add, 50mm 1.4 add, 50mm 1.8E, 100mm 2.8E, 135mm f3.5 ais i already have (for my 2 D700's + F100).
Going for the R would mean buying two R lenses: 60mm macro as alround lens and wide portrait lens and the 28mm f2.8 for wider shots. My Mlenses are 24mm, 28mm, 35mm, 40mm, 50mm, 85mm, 135mm (shoot mostly 28/35mm on M).
Nikon would be smart since i have most glass already. But hen if the leica R feels better and i can find some nice glass. I could just start with the 60mm next to my wider M lesnes.
To make it less easy..i found a Black OM1 with 50mm1.4 for 50 euro. I have a 28mm f3.5 somewhere so i would almost be ready when this set is ok and doesn't need extensive CLA done to make work. Didn't handle it yet.
The FM3a and R6 are the youngest kids on the block. The OM or Pentax systems or much older and more probable to need servicing. The leica R6 will keep it's value and probably the Nikon too. Judging from the expereience with the FM bodies i think the the Leice R6 might feel sturdier and more like the M and quit possibly have a less loud shutter. Also nice points..
So i guess the smart thing is to go for FM3a/Fm2. since they are definitely quick and can be serviced everywhere and probably have a better chance of getting parts. And i have glass.
My other persona likes to give that R6 a try. The M6 i have just feels so good. Ik that R6 has some of that feeling.. and if it was good enough for Salgado etc.. Would more probably need a CLA. Any one know the cost of a CLA for Leica R6.
