I'm still not sure how focus adjustments are made in the lens firmware/rom data. Focus is achieved with a feedback loop via the phase detect sensor and/or contrast detect.
camera: *samples focus point(s)*camera: Lens! Advance focus by -this- muchlens: ok, donecamera: *samples focus point(s)*camera: err, you didn't quiet get there, shift focus by this small amountlens: ok, donecamera: good enoughcamera: *releases shutter*
Is the whole point of micro adjustments in lens firmware/rom intended to get the first focus movement to be more correct with less fine adjustments after that?
Why was this even an issue back in the day of non electronic 'dumb' geared lenses?
The lens doesn't know its in focus, only the camera does., even with the fanciest electronic lenses.
Jim Evidon: Back in the good old days of rocket research, we used to rely on a high fps rate camera called a GSAP to study rocket engine firings. It's total running time was a matter of seconds. It cost a fortune then.
Now there may be one for less than $700? What possible use can an amateurphotographer have for such a device once he has taken a picture of a hummingbird in flight or a bullet shattering a light bulb? It's a marvelous achievement in price vs. performance, but it's long term use to the average photographer will be in bragging rights only.
Someone said he'd pick one up in a heart beat. And do what with it? Do you have any idea how quickly it will fill a 32GB card at 18.500 fps @ 2560 x 2048 pixels per image? I would imagine we are talking in terms of seconds.
It has a profound scientific future and I cheer for the inventor, but aside from that who in amateur photography needs it? Who will want one is another matter.
This is what's always said before a new product comes to the consumer market.
Where's raw mode apple?
DPR community: 2009"Its impossible to design stabilization into wide fast zooms"
How does this account for shutter lag?
No raw? Booooo.
Perfect lenses are really boring. Maybe for scientific work.
Ha. These are just using the QD(quick disconnect) system for rifles.
The GH series really needs to be able to record 422 10bit or better internally by now. Sony is behind here but still they should be able to as well.
So its been over 8 months since this article. Assuming they started work before this article was written, it doesn't take that long to add what is essentially a 'basic' feature as it doesn't require any post processing. Where is this?
'Flat' video color is a step forward but for this class of camera you really need 10-14bit linear color(raw or whatever) video.
A bit heavy on the grads there.
Wheres raw??? Come on Apple.
No CFA is great but its just too expensive. I'd be all over a $3000< Sony A series B&W camera. Both a high sensitivity 12MP version and high resolution 36MP+ version.
ArcaSwiss: I once bought a Samdung (sic) Blu Ray player. It failed quickly. I sent for repair and when it came back it still didn't work
Never again Samdung for me.
I had a bad experience with a Sony camera so I'm not going to but a PS4.
Lederhosen: Again with the complaints about the clickless wheel? Get over it, DPR. Some people like it, others don't. Your obsession with it is blinkered, subjective, and completely out of proportion. "The wheel does not click, therefore I cannot love this camera!" Please.
Actually the clickless wheel is annoying. I can understand if its primary use was to control a step-less function like zoom or focus but it has to do it well. Otherwise it makes no sense for step settings which is pretty much everything else on the camera it could be bound to.
IMO I've never seen a good electronic control for focus or zoom so it begs the question why?
Re: Touch screens
People need to realize that just having a touch screen does not a good UI make. Apple and Google spend lots of money and time developing their touchscreen SOFTWARE. If you just put the hardware in the camera and let a UI programmer out of school work on it for a week you'll get what most touch screen cameras have which is junk.
For a really good and unobtrusive touch UI you need:
I think camera companies can maybe scrounge really hard to get 2 of those but I definitely don't think they can hit all 3.
Jay Jervey: What is the story on this caveat from the press release page?
"An SDXC memory card with a Class 10 or higher speed rating is required for XAVC S recording."
So you need >64GB extended FAT format for 50 Mbps video? Why? What does that have to do with it? I think they mean you need a UHS-I Speed Class 3 card like the new ones from Kingston that are targeted at 4K video. But they come in 16 & 32GB SDHC as well as 64GB SDXC. So why SDXC only? I can't read SDXC with my laptop SD slot.
I doubt that you -need- SDXC. Its not like these press statements and spec pages are all that well edited.
Besides, no one will care that your old laptop can't read SDXC anyway.
martinj68: it's a shame that the zoom range is even less that the first two models.short zoom was the main reason i didn't buy the mk1 and 2.
Also why is Sony so reluctant to add touch screen to their cameras?
Joking right? A longer-slower lens and a touchscreen are not what the primary customer base wants in this camera.
"You can't put an internal EVF into the RX100 class of camera. Its just not possible." Oh wai...
