The Superzoom which actually DOES it

Hi Trog (and everyone else)

I have a GX7 and a Mk1 14-140 Panasonic Zoom lens. ... and often get 'unexplained' blurry photos.

I am well aware of what shutter shock is - and what it is caused by, but on a GX7 this can not physically happen when electronic shutter is switched 'on' as there is no mechanical shutter or parts moving.

I do however feel that Panasonic's 'in lens' stabilisation is poor - in that it is under-damped. I have three Pannasonic lenses and all when 'swung' into action take a fraction of a second to 'settle down' before a blur free shot can be taken.

Interestingly the unstabilised Olympus lenses I use on the GX7 do not suffer from this, which I assume is down to the GX7 then using its own inbuilt stabilisation, which in my opinion is excellent. ....Sadly we can not switch the GX7 to use only its inbuilt stabilisation for Panasonics own lenses.

When you said 'optically its very sharp but mine suffers badly from shutter shock on on my GX7..' Are you suggesting that you still get the odd shutter shock blur even when using electronic shutter?

I ask, because I do frequently get the aforementioned unexplained blurry images especially at the long end of my MK1 14-140, even when held really steady and on burst mode - which shouldn't shake the camera at all?

PS: My MK1 14-140 is staggeringly sharp at the wide end right up until about the 100mm mark, but after that is softens off to only just acceptable for non critical images.

PS. AdamT, thank you for your report and feedback.
