The only other person I've seen on the forum that shares my consensus the M4-2 was crap that just about shut the Leica doors.
I really don't think it is apples to apples comparing digital to film. I have 3 or 4 high dollar "state of the art" digital cameras over 5~10 years old that aren't worth the effort to even try selling. Forget any needed repairs, they aren't worth it. A complete overhaul (more than a CLA) of a Leica film body from the most respected Leica repair shop won't run over $500, and it will last another 30 years before needing maintenance. Compare that to my D750 introduced in 2014. 2 years ago mine malfunctioned, Nikon would not honor the warranty without a receipt proving I bought from a USA Nikon dealer (about 3 years ago for $1500) and the repair cost was ~$700 at an authorized Nikon repair shop. Today the Nikon isn't worth what I paid for the repair while the M4 is worth twice what I paid for it 5 years ago.
And there is no comparable film RF on the market today or in the last 20 years to compare with a film M model.
Well, for digital I mostly have bunch of made in Japan cameras. They are older than 10 years and works. Even original batteries, made in Japan, still good.
Where your D750 is made? Thailand. And this is it.
With my Canon DSLR it is not about how much they cost now, but about them working as new without repairs. No, one of my Canon DSLRs is on its second shutter. Because I'm third owner of it. At least. Previous two I'm aware of, used it for paid photography. One of them is our daughter. She used it professionally without having any backup.
To make my M4-2 "good" I have to at least replace curtains on it, lugs are also getting thin. YEE price:
M body CLA + curtain change Leica M1, M2, M3, M4, M4-2, M4-P
(labor only, curtain cost see below) $240.00
M curtain - long $100.00
M curtain - short $85.00
Leica M2, M3, M4 body new strap steel lugs during CLA $80.00
505 USD, before two ways shipping Canada to USA.
Haha, don't know anyone who uses any film camera as a digital, but even if Gary Winogrand was still around he'd still be able to get his M serviced; if he were shooting Canon he'd have been through 12 bodies over the same time frame. 😀
Seriously, I was just comparing the comments of those who think a $1200 Leica film body is outrageously expensive but think nothing of a $3000 Canon digital body, when the former will still be worth at least that much (if not a lot more) in a few years, whereas the Canon will be worthless.
I used M4-2 for thousands exposures per year. Number of scans was not far from numbers of digital exposures in LR count.
Garry would ditched film just as Parr, Gilden and many if not most others did. Film is not used by those who needs exposures for results.
Also, Garry didn't just have only two worn out M4. He was buying used film M from good to him dealers and was bringing his film M for repairs regularly and locally. Now? Send it for DAG and wait for months if not longer? Or somewhere else and wait. And I doubt he would be able to sent it to Leica Camera AG for repair. He was not a rich person, he told "I'm surviving" and it wasn't joke.
To be honest I like the fact what more durable mechanical Nikon F cameras lasts, but don't have outrageous prices. It just feels normal.
It might be odd, but I care more about cameras durability as long lasting term. And film M are not cameras like this. If in real use, not roll a month "use".
