I just found this article on the site's sidebar while reading another article
about the Ricoh GR III. I was curious about that camera as I knew nothing
of its existence until a post elsewhere here had me looking into it.

It's a pretty interesting read, particularly with included pictures.
There's even a pic to illustrate a metal retaining clip having jumped off
its securing tab.


Another interesting piece of information is about 5DIV and 1DX bodies,
and variations found in those:

Roger wrote:
Upon further inspection of the most affected camera bodies, Roger discovered each of them had a history of a drop or required ‘significant internal work’ after being rented out at one time or another. He also notes it makes sense these cameras are more susceptible to damage when bumped or dropped due to the tendency for these cameras to be used in harsher conditions and with longer, heavier telephoto lenses, which could more easily bend the mount ‘because force proportional to mass and all.’


Anywhoo, I thought some folks here may be interested in the article (external link).

Interesting article. One thing I find interesting is the statement

First let me mention that we asked and answered the obvious question “does the IBIS system change the flange-to-sensor distance.” We took some cameras, measured them, put a lens on, focused it on various things to run the IBIS, and measured again, about a dozen times each. Each camera had identical measurements every time.’

With respect to Sony, does this really answer the question "does the IBIS system change the flange-to-sensor distance" or does it perhaps suggest that there is a "park" position of the IBIS system. Is there a way to measure the flange-to-sensor distance with the lens mounted?

It was an interesting article. It might start some more paranoia in some users when their camera isn't working 100% perfectly all the time but I found it interesting that some relatively large breakages didn't result in particularly large outliers

As a 5DIV owner the take away I had was:

Don't drop the camera.

I think that's pretty sound advice. :)


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.
