Writing from memory, I recall that the Z9 does have a special guard-shutter, not connected with exposure. The arguments that Canon might have deliberately omitted the closing function as a safety feature are cogent. I have never had problems with dust on sensors with DSLRs as I treated them like a bacteriologist handling Petri dishes - open surfaces always facing down as far as possible and avoiding drafts.
Reading all this conversation about R10 and shutter, I would ask some more questions :Oh, ok, that changes all!
I had given for granted that we were talking about a firmware castration (also because other people already agreed with me that "Canon should add the shutter closure in future firmware for R10"), because, to my knowledge (plese someone correct me if I'm wrong), there never has been any digital Canon ILC that omits the mechanical shutter, so I took for granted that everybody here is aware that all canon DSLR/Mirrorless (D, M, R series) have a mech shutter (at least to date).
Did you never own the original 5D Alan ? At f/16 the sensor used to look like a teenager’s face with a bad dose of acne.
Shutters do vary in their weight and strength, yes. The Canon 5DS / Sr ‘s are paper thin and I’ve seen pictures of ones that have been bent and damaged by someone using an aerosol air jet on them.
IMHO "should" is the right verb. I'm still convinced that adding some potentially "floating" mechanism to a sensor cage, even if parked, can only add weakness to the whole thing. At least, it adds parts that can be damaged and may be more complicated for beginners (which goes your way of thinking, I guess). I found this at Lenrental on the subject :
300D, 450D, 7D, 7DII, 5DIII, 5DIV, 90D and 5DSR, but not the original 5D. Never changed lenses with the 300D and 450D, and since then my bodies had good shake clean. The mythical dust-pump activity of the original EF 100-400mm didn't seem to affect the 7D - mind you, my copy was so soft it would have done an analogue skin smooth of an acned teenager.
That sounds fair. For the rest, I wasn't discussing of segmentation and personal preferences, but I do get yours.
Well, I never wrote (or may I say mean) that the missing IBIS on R10 was due to a possible fragility of the system when used by average users (to me it's just cheaper without it if we're looking for a reason). I asked about the fact that this missing IBIS could be a one more reason (in addition to the reasons you gave that I agree with) for having less the necessity of having the ability to close the shutter... that's quite different.I talked about segmentations just to argue that the missing IBIS on R10 wasn't certanly due to a possibile fragility of the system when used by the average user, contrary to the shutter curtains which are easier to damage then the IBIS on the sensor, and so the non-closing shutter was probably a practical choice from Canon rather then market segmentation
High megapixel for an R5.
