True...but an ND filter costs a lot less than $1200, if you need to shoot f/1.2 in bright sunlight.
The situation where the lack of 1/8000 hurts is bracketing in bright light, for example if you've got the evening sun in the picture... and you can't use an nd filter here, because you also want to have the shadows in one bracket.
or going from 1/180 sync to 1/200...
My main issue with the slow x-sync is not the difference to 1/200s, but that you have to set 1/2ev exposure level increments to get it (or it's 1/160s) - but that *also* means you can only set 1/2ev flash ec steps, which are far too large steps for ettl metering :-(
I didn't succeed yet to force 1/180s on the 6d in 1/3ev more through Magic Lantern because the canon fw forces it to 1/2ev steps... the only way to combine max. x-sync with the smaller steps is in Av mode with a fixed 1/180s shutter speed (in the flash menu).
or an extra 50k shutter cycles 5 years from now (pretty sure I will have sold my own 6D before it even hits 30 or 40k cycles...let alone 100k...my 50D only had 25k cycles in 4 years.
Oh my, I'm at nearly 10k after one month (I shoot a lot of fluffy things that move around), I really hope the 6d shutter is sturdier than what the spec indicates, my 100k rated 60d is still fine @150k cycles :-o
Thanks for setting me straight, certainly HDR exposure in that situation would be helped by 1/8000/sec...but I think I could get by without it anyway...perhaps with an ND filter that is weaker (to be able to bracket for the shadows as well...or else remove it). I don't do much HDR, and none directly into sun that is not shrouded by cloud...if that is what you're referring to. Those images have a trite look to them, to me. And clear skies can be boring.
10k in one month is kind of high. You sure you've only had the 6D for a month? Could have sworn you were talking about your 6D like back in June or whenever it was. You should use more than one body (or perhaps you already do have more than one 6D). 10k on the 6D in a month, which only fires at 4.5 fps...you're working it a lot aren't you? What are you shooting?
Are you implying you honestly think the 6D's shutter could be less robust than the 60D's? (Since it is apparently exceeding its rated life for you already?) I guess it's possible that it could be of lesser quality than the 60D's
, time will tell. I would bet big that it is not lesser quality, or less durable. Still, I won't be keeping mine to 100k cycles. Perhaps 50k if I go really nuts, but not more than that...assuming I don't lose track of the count before then.
