Thanks. This seems to be the diagnosis. It has been regularly erased and formatted as well. I'm going to do a test with two cards recording, later today. Will post result.

Thanks Andy. I can't say about preview as I'd deleted the images before I spotted problem in computer. This camera takes two cards. I'll do a big test with two cards operating and compare. The two ...

Hadn't thought of that. Interesting. Thanks.

Is this an early shutter failure. I can't remember seeing it before. Somebody out there knows, I hope!

Fabulous.

I've got a good lot of Canon kit. 1Dx's 300f2.8, 400 f5.6, 70-200 f2.8 ii, 70-300 L etc. I got two Sigma tcons cheap years ago. The 1.4 is lousy and the 2x is superb by some chance or other. I've ...

Very thorough review. I like that. I've had the 100-400 for a couple of weeks and I think it's brilliant. Mine doesn't have a stiff zoom ring or any of that. It's slightly stiff to mount, but ...

I've big heavy Canon kit for years but recently got an OMD-Em1M2 outfit with 14-40 and 40-140 pro and tcon 1.4. I'd a look at the 300 f4 pro but decided it was very long to be a useful single focal ...

I've been using Macs for years. The best OS I've ever used (have used Dos, CP/M, Windows and Mac) was Mac OSX Snow Leopard which I still have on an old iMac. I can't ever remember it crashing....

Some of these were 100yd distance, handheld 640iso. Hit rate (af) about 40-50% which is great at 18fps! Going hard here. She ran in the Rio Olympics in the steeplechase

It does. That's how you have to do it. So it's a reverse. In the Canon you can lock with the back button OR use it as in the Olympus. You get totally used to it.

I've tried it on my Canon system, but I exclusively back button focus on the EM1_2. I think you more or less have to. On the Canon you can use the BB to lock the focus. Can't on the Olympus.

I've mine of an E1M2 as well. I find that using the OS or the IBIS are much the same, but I think the OS is marginally better. What settings do you use?

You can get lucky though. I bought on-line, cheaply with some trepidation. Perfect lens, no zoom stiffness, really sharp out to the limit. Slightly sharper at 300mm. Slightly. For 800 equiv, amazing.

Placed 15^th in the challenge. My daughter exploded with laughter during her wedding at something her sister said. It's her favourite wedding photo.

So's mine but everyone says they're like that. As it's due to rubber it should create no problem.

I little bit stiff. Looked it up. Due to the rubber ring. Apparently if you take that off it makes it easy, but I reckon it's harmless. The focus lock in mine is fine. No real stiffness. I'm also ...

Must get around to trying that!

50yds (Guess) or so across the River Lee, handheld. This is a very impressive lens.
