I really hate it when considerations are confused with "war" for some... Clearly, none claims that LS should be abandoned... none claims that one shutter is superior than another.... The only claim is made to the extend of appliance here... Camera's have customers with different needs... there are people that claim 1/2000 sync is necessary for photography to exist, there are others that claim that photography hasn't benefit anything, anything at all, from pushing flash sync further than 1/250... I'm (personally and without trying to "compete" with other opinions) with the second... My opinion is, that studio photography hasn't benefit at all from increasing flash speed more, I haven't seen anything as an image result that proves "innovative photography" worth considering because flash sync increased further than 1/500...
OTOH, it is a fact that LS raises prices, it is a fact that lenses are bulkier, slower and more keen to failure, it is a fact that servicing costs are multiplied and it is a fact that reliability is degraded... Can one (for a change) talk on the subject set, than defending his investment or his company's selling (BS) point? ...Can I see a picture that is a breakthrough in photography, sold for millions, couldn't be done with 1/250 sync and was shot with flash use of more than 1/250? ...may I?
This is a simple wonder why focal plane shutters on MF are stuck with 1/125 max sync... It also questions the consequences that could affect industry if 1/250 sync speed was applied on modern MF and View/tech cameras... nothing more, nothing less!
