Re: EM-1 Lock-up Information

Those dots are pretty weird. They don't look like any sensor dust I've ever seen before. Maybe an electronic aberration? Good that they've gone now.

Re: EM-1 Lock-up Information

Unless you're using an insanely small aperture, this is definitely not dust. Dust, if present, will be on the outermost panel (the anti-dust shaker) which is some distance (comparatively) from the sensor; as such, it will appear as diffuse blobs.

The example here certainly looks like pixel data is missing, but it's clearly random pixels being affected which might indicate some sort of electromagnetic interference whilst reading the pixel data from the sensor cells.

Re: EM-1 Lock-up Information

It may be worthwhile for a mod to carve this pixel mystery out into it's own thread. It would be interesting to see what the outcome of this may be.

Re: EM-1 Lock-up Information

Currently on an overseas trip to sunny climes - yesterday had two lock ups while taking sequences of runners and using caf. Both times resulted in losing the close shots I was after. Hope this doesn't continue for the whole trip.

Re: EM-1 Lock-up Information

Hi, It happened with both a SanDisk Extreme Pro (95 mb/s) and a Transcend 600x (90mb/s). It was also a hot day and I was out in the sun with the EM1 for about 4-5 hours so I do wonder if heat had something to do with it. It's all a bit annoying to have these lock ups during 'key' sequences during the Noosa Triathlon as I've had no others. Fingers crossed that its ok for the rest of the trip.

Re: EM-1 Lock-up Information

I've just received confirmation that a replacement body is on its way back to me from Portugal (thanks Chris). Looking at the serial numbers it appears to be an earlier body than the one I purchased from Jessops, so lets hope all the bugs have been removed before despatch.

If I get it in time today I will give it a work out on a shoot tomorrow (going to Petworth House and Park and hope to see some of the Stags in action if I'm lucky)

Re: EM-1 Lock-up Information

Just a thought - what size cards is everyone using ?

it may be big cards are overloading the system and unlike, Windows OS - there is no cache for when RAM is exceeded to buffer ?

Re: EM-1 Lock-up Information

Only use 16Gb cards. (Sandisk Extreme 45Mbps class 10) On the occasion it locked up, I only had a couple of bursts of 7 shots with minutes inbetween, so I don't think it's a buffering problem in my (unrepeated) case.

Re: EM-1 Lock-up Information

The Postie has just delivered my battery grip from Germany

no MM-3 adapter - yet (but I registered for that later)

either they haven't accepted my claim for that or it will arrive some time in the future, more "wait and see time"

All I need now is my camera!

Brian, I only use 8 Gb cards - because I do not want to "lose more than that amount of images" if a card fails on a holiday/day out. Also it is a more manageable amount of Gb to review, prior to upload/delete on my small laptop when we are away travelling and loading to an ext HDD for backup

Maybe,larger chips 'cooked' the processor ? processing units tend to get hot under load !

Re: EM-1 Lock-up Information

if "Larger chips" are the problem its an Olympus problem as they specify no limit to card size

I don't think its very likely to be honest as I am using the same cards without problem in my EM-5

Brian, I hear what you are saying BUT the 5 is very different to the ONE

I am just going on my Exp with IBM on the Study group at Boca Raton, factory in 1981 and PC/DOS prototype O/S and even 3.1 et al read/write to silly 8" floppy disks

Yes, I agree its an Olympus problem
