Biowizard: Most of the damage seems to be due to sudden thermal shock. Chances are nothing would have fallen apart or cracked if the temperature had been dropped slowly. Bit like pouring boiling water into a cool wineglass - rather than slowly boiling water in the same glass, perhaps in a microwave oven.

Brian

Agreed, Richard - however, the popping off of backs and front lens covers strikes me as most likely to be due to rapid differential shrinking, combined with hardened pressure sensitive adhesives. Had everything been allowed to chill, slowly, together, these parts would probably have stayed in place.

On article New 20mm F2 4.5x macro lens released by Mitakon (122 comments in total)
In reply to:

philzucker: The working distance seems actually to be 20 mm - that's what the specs on the manufacturer's website say right now. Makes more sense for a 4.5 magnification than a 20 cm working distance at 20mm focal length ...

That was my instant thought when seeing the original 20cm mention. Anyone who could make a compact lens that gave 4.5* magnification at such a distance would have to reinvent most of the rules of optical design, and probably some of the laws of physics! 20mm feels about right ...

Biowizard: One clarification badly needed, please, DpReview. Your (edited) statement says:

"Using HDR, Focus stacking, Hand-held starlight in scene mode, **AND** keystone compensation with Rec view 'Off'."

Do you really need ALL these settings on at once to get the problem? If so, I'm surprised anyone ever got affected!

Should that "and" be "or"?

Brian

Fine, be a Troll. Can't be bothered to waste electricity on you, even though you are wrong. Have a good life.

Dear Clayton1985 - you have missed an important point. YES, I do own the camera, but NO, I have NOT yet updated to 4.2 Firmware. So my question is entirely valid.

DWinter, I am NOT being pedantic. This is obviously a "boundary condition" software bug, and with something like 40 year's experience in the IT business, I TOTALLY understand the importance of being explicit about the conditions. Only by knowing the EXACT situations in which bugs rear their ugly heads, can you figure out how to fix them. And the is a WORLD of difference between "AND" and "OR".

Biowizard: Silly question: what was Firmware 4.2 supposed to do that 4.1 didn't?

Brian

Thanks Mike - I did finally find the above info after lot of hunting around: 4.2 did not appear to be on the Olympus USA updates page, but is on the UK site.

Close thing - I plugged my E-M1 in for a routine firmware check only last week, and was told that my current version, 4.1, was the latest. I'll leave it there until 4.3 comes out!

On article Ultimate OM-D: Olympus E-M1 Mark II Review (1378 comments in total)
In reply to:

WhiteBeard: I know I'll be blasted for this by all the Oly fans and I also know dpreview is not Consumer Reports but before giving such an outstanding "Build Quality" score, I would either a) disassemble the camera to see how its predecessors reliability woes have been addressed or b) wait a few months (after all, DPR waited long enough for a GX8 review, but I disgress).
I find it odd - and slightly disturbing - that reliability is never addressed by DPR, especially in case of "Pro" items fetching an impressive price tag.

My oldest Olympus body is an OM-1n that I bought in 1976. Still works perfectly. My E-1 is about 12 years old, and has never shown any sign of bad behaviour. And my OM-D E-M1 is fairly recent (2 years), and beautifully made, working perfectly. It even feels a little like my OM-1n in the hand.

Definitely cameras made with care, and extreme quality. Anyone who breaks three of them, is either massively unlucky - or less than careful with their gear.

On article PogoCam is the world's smallest wearable camera (37 comments in total)

Excuse me - this is late 2016.

Just a 5 MP sensor and up to 100 still images? Or worse, up to 2 minutes of 720p video at 30 FPS?

I have a micro-SD card smaller than the size of my little finger nail that contains 256Gb of memory. Why this pathetic capacity?

Gimme 12Mpx, 2000 uncompressed RAW images, or 60 mins of (at least) 1080p @60fps, and then I might say, WOW!

Perhaps it's time to begin a KickStarter on this one ...

On article Ultimate OM-D: Olympus E-M1 Mark II Review (1378 comments in total)

I have a BIG problem. I still LOVE my OM-D E-M1 (mk 1), and look smugly "down" at those toting big Canikon beasts, knowing that in nearly every situation, I can take the better photo with my gear. Hand held in failing light, or critically focused by hand.

But this Mk2 has SO much extra, I am very tempted to update. I can't justify owning both, but my Mk1 is nowhere near ready for "recycling".

Bother.

The new Oly would be my absolute camera of choice if I was only just upgrading from my 10-plus year old E-1; everything about it is delicious.

But I did the E-1 upgrade a couple of years ago, and totally love my OM-D E-M1. Not sure the Mk 2 version has enough for me - as a 99% stills, 1% video photographer - to want to upgrade. YET.

Cdembrey, sounds like a wonderful camera - but it would also need a Chinook helicopter to fly it remotely! Somehow I can't see DJI getting a spinning mirror/shutter into the GoPro-sized camera on its consumer drones!

Peiasdf, yes I did ...

60 frames per second,
60 seconds per minute,
60 minutes per hour ...

... is 60^3 frames per hour!

And 300,000 / (60^3) is 1.38888..

otto K - I would hope so. Any mechanical shutter in a camera that size, opening and closing 60 times a second, would not last long! Give it a generous (say) 300,000 actuation cycles (same order of magnitude as a pro-level DSLR), and with 60fps, 3600 seconds in an hour, let's see:

300,000 / 60 / 3600 = 1.388 hours of life!

beavertown: I may consider Microsoft notebook as my future computer, one factor stops me from doing so is the vulnerability to viruses. Are there any MS Surface users who know if a surface book comes with a built-in anti virus program, I don't mean third party or trial version, I mean something like Apple does that will take care of it and you don't have to spend extra money to get an anti virus program.

Windows 10 includes what used to be called, "Microsoft Security Essentials", a fairly comprehensive A/V package that is updated daily if you want. I use the above on Windows 7 upwards, and don't feel the need for additional A/V programs from third parties.

To be fair, it is not just post Jobs, and it's not even just Apple. All types of computer interface have disappeared, to be replaced, over the years. When was the last time a new computer shipped with a 25-pin (or even 9-pin) RS-232C plug? Or a Centronics/Parallel printer port? Where are the 8-inch (late 1970s), 5.25-inch (early 1980s) and 3.5-inch floppy drives now? My MacBook Pro (2012) still has a DVD-drive and Ethernet port, both of which vanished in the first "Retina" model. And so it has always been.

I actually quite like the idea of USB-C/Thunderbolt 3. If only all my audio interfaces, cameras, and more had the right connectors on. 5 years from, I suppose all my stuff will be USB-C - just as Apple changes once again.

Biowizard: The big killer for me, is the loss of function keys and a physical escape key. There is SO much space on the top-plate of the Mac, surely they could have included a full keyboard AND the toy-graphics OLED strip?

Brian

Yes, I know you can get an icon up on the touch bar - but I did say, "physical" ESC key. If I wanted to type on a screen, I'd use an iPad!
