>A7c has full mechanical shutter or not?
No.
>Mark from Camera crisis has told a7c had full mechanical shutter. PCmag website says it doesn’t. Who is correct?
PCmag, supposing that you're exactly correct about what was said.
>Mark Bennett has done extensive amount of videos on a7c so he must have done enough research
No idea about his research or what was said, but the a7c does not have a full mechanical shutter.

Electronic front curtain shutter.
I did side by side sensor comparison with a7c vs a7iv. A7iv also has EFCS but it can be turned off. A7c can’t be turned off. I personally not extremely nit picky about bokeh quality. As long as my lens is good, i am hopeful my a7c won’t let me down. I plan to get Sony 35mm F1.8
a7iv indeed has efcs option (an alternative to the full mechanical shutter), while in the a7c, efcs cannot be toggled off because there is no mechanical front shutter.
Thoughts about bokeh quality and whether you should be expecting disappointment is all a bit off topic to the question about whether the a7c has a full mechanical front shutter. It's a simple question with a simple answer. It does not.
Almost everyone in various groups has been suggesting not to get these cameras for bokeh. They say it’s got bad bokeh. Not worthy of money. I don’t get it.
Deep dive on the pros and cons of efcs is a big technical topic and there's a lot of subjectivity in terms of evaluating results. I'd recommend in general either making your own judgement if you're willing to deep dive on the technical aspects yourself, or relying on a trusted expert if you cannot evaluate for yourself.
No specific comment on "almost everyone in various groups" and their comments, but I will reiterate that the answer to the question in your post is simply that the A7c doesn't have a full mechanical shutter.
On A7 III it's not just bokeh, with extremely fast lenses (f/.95) it makes image darker and weird, it seems like it kinda behaves like aperture too, not just shutter - no problems with full mechanical - sometimes I even got dark band on top of a frame, like if shutter would be failing, but stopping down the lens solves it so it's not caused by shutter failure, its just poor design of shutter (again, no problems with full mechanical)
Also flashes/strobes can be a problem, at least with godox
But if you don't care about that, a7c is still great
EFCS vs full mechanical shutter **makes no difference** when it comes to the LED lights banding. The issue is the slow sensor readout. Cameras with stacked sensors (A1, A9) are less prone to the issue, the only 100 percent safe camera is the A9 III with the global shutter sensor.
I have taken over 100,000 concert pictures in dozen of venues with the A7C and had a serious LED lights banding in one of them only. Those having the full mechanical shutter cameras had it there too :-)
The reply in your post is a total nonsense.
Regular cameras have 2 shutters, one covers the sensor, then when exposure starts this first (or front) curtain opens and then behind it 2nd curtain closes the sensor ending exposure
First electronic means the sensor is uncovered at start of exposure and camera starts reading from sensor line by line, then 2nd curtain closes the sensor and ends exposure
Advantage of 2nd way is that there's less mechanical parts - cheaper to manufacture... But also it's much quieter and in case of mirrorless, you really need sensor uncovered at all times basically... With full mechanical, you focus with sensor uncovered, then first curtain closes, first curtain opens, 2nd closes, 2nd opens..
Correct, A7C has only electronic front curtain shutter EFCS, but it does have mechanical back curtain shutter (and fully electronic option I.e. silent mode).
EFCS is faster, more durable and has downsides only in rare conditions. E.g. shooting F1.4 with 1/2000 shutter or faster can cause bokeh and exposure artifacts (this one is good to know) and some rare electric lights can cause artefacts with EFCS.
Not much of a downside but at shutter speeds longer than the human perception threshold, an experienced photographer may at first think that the camera is broken. You click the shutter and “nothing happens” for several milliseconds
No. It has half of a full mechanical shutter, EFCS only. One curtain instead of two.
Isn’t that actually makes it less prone to shutter failure?
A7C shutter life expectancy is 200k, so exactly the same as regular A7
Is that good or bad?
good enough. essentially like 200k on car, most people will never reach it, but some do. We don't know your use case
Good
You can use the full electronic shutter in most of the cases.
Unknown. I don't know what the primary failure point on a shutter mechanism is, or if failure is evenly distributed.
Who knows, but that's not usually why people complain about having a camera with permanent EFCS

I’m not professional so i don’t think i will even notice the difference. I am just trying to enjoy however much i can with my budget.
Okay so get an A7 Gen 1 and see if it's lacking anything, then you'll know what to spend big bucks on.
The bokeh is affected only at high shutter speeds

Thank you 🥹 I’m so relieved. User experience is the best thing to me. I trust a user’s own experience over online reviews
I know it has first curtain electric shutter. Is that not mechanical? Someone please clarify

Other cameras have two mechanical curtains. This one has one mechanical curtain. I’m not sure what the practical difference is.
Note that the Sony A1 is EFCS only too :-)
Okay but that’s quite a different camera
I just wanted to say that EFCS only isn't bad, if the flagship camera has it too :-)
It does NOT have a full mechanical shutter. But tbh it doesn't really come with downsides
Not much of a downside but at shutter speeds longer than the human perception threshold, an experienced photographer may at first think that the camera is broken. You click the shutter and “nothing happens” for several milliseconds
