On article Samsung launches first removable UFS memory cards (177 comments in total)
In reply to:

Nick Brundle - Photography: Give it 5 years and it will be standard in most electronic goodies

How many cameras are using the Nikon D5 XQD memory card ? and how long it has been on the market ?

If anything it will be a very long time before anyone other than Samsung. If they are so sure about the new memory format perhaps the next Samsung Cell phone will have it instead of Micro SD. We will wait and see.

Kiril Karaatanasov: Brand new Memory Stick! Wow! How exciting.......

I am very relax, by the time this format come out on my DSLR I'd be too old to worry about it. Stick with my tried and trust CF

rjalvarez1957: I have a Nikon F2 which appears to have a cloth shutter.

Nikon F3 has the removable back
Problem with horizontal travelling focal plan shutter is the slow flash sync of 1/60 sec so camera makers start using vertical shutter units - and this can only be made out of metal blades to improve sync speed to 1/125 sec. Nikon was the first to design a 1/250 sec shutter module for the FA camera.

My 1970 Pentax Spotmatic 1 and later SP 2 both has horizontal cloth focal plan shutter.

kodachromeguy: For two decades, I used a late-production F (1972?) with some of the cosmetic features of the F2. Mine had a titanium shutter. It really was a superb precision piece of machining. The finders clicked on and off with precision. You could install any one of about 20 finder screens; I preferred the grid screen to help keep horizons straight. Mine had the viewing-only prism, not the metering head. A friend has it, and it is still in occasional use. It would be curious to see what proportion of present Dpreview readers could use a mechanical film camera like this.

I have a F3HP - not quite as old as the legendary Nikon F but it is a manual camera nevertheless

On article Nikon offers free battery exchange for D500 owners (96 comments in total)
In reply to:

pkcpga: I think it's very nice that Nikon is exchanging out old batteries that are long out of warranty for new ones, most companies would not extend this exchange on 3-5 year old batteries.

This not the first time Nikon does this - The old EN-EL3 was replaced by the EN-EL3e - the batteries have the same shape and the same voltage - the EN-EL3 has 1400mA the En-EL3e has a marginally more capacity at 1500mA. The only different is that you can use the new EN-EL3e on the old Nikon body such as D70 but the the old EN-EL3 can not be inserted into the new Nikon body such as D300s. In other words the EN-EL3e is backwardly compatible. Fast forward to 2013/16 the EN-EL15 version 01 still can be used in the newer Nikon body such as D500 with reduced capacity due to electrical discharge profile - otherwise electrically and physically no different to that of the EN-EL15 version 20, But it is nicer to have the latest version so Nikon is basically give you a free exchange - old for new. The only condition is that you must be an owner of a Nikon D500 bought through a Nikon authorised dealer. Must check with Nikon Australia

Not really, if using the old battery may cause problem then it is the responsibity of Nikon to recall the old ones - it happens every where to various insdustries, especially automotive. The fact that it only has problem when using with the D500 - that allow Nikon to selectively replace the old ones only the for D500 users.
If I have a D500 I surely will send my one ones in and take no risk that one day I may forget and use the old battery with the new D500.

I don't think Nikon packs the old battery which is out of production since 2013 with the new D500 the issue must have to do with people who has old EN-EL15 which is not 100 percent compatible with the D500 power profile

My D800 came with a EN-EL15 Lion01. If I buy a D500 today would I be able to exchange the old battery for a new generation one ?

Yeah - by the time the D810 Review hits the website Nikon would possibly have the D810s (or equivalent) available for purchase.

lescrane: well, no matter how you slice it, it's good news if you own the lens as opposed to having to buy a whole "II" new/improved lens.

That being said, although I paid for the dock and don't agree w/the previous posters "I'll buy and return from Amazon" notion, Sigma , for their own sake should just include this with the lens (even if it means inc. price20.00). Assume the dock costs about 10.00 tops to make. How much will it cost them to receive, repair and send out hundreds, if not thousands of lenses for those who choose to go that route?

$60 is cheaper than some lens hood which is basically a piece of off cut plastic tubing - try buying one for your Nikon or Canon lens and see how much they ask for it

mais51: Most focus problems are lens + camera body related that is why camera has fine tune feature built-in so how adjusting a lens independent of the specific body would fix that problem at all. The USB solution could only fix whichever problem exits with the lens. Could someone more knowledgeable in this field please explain

Thank you - that is what I understand should happen. I don't believe it only takes 10 minutes as the Lens Rental article seemed to imply.
-Take a photo with the lens-alight
- note down the required adjustment
- remove the lens - mount on the dock
- run the program make necessary adjustment
- retake the photo - check focus - repeat if necessary

Repeat the same procedure with various focal lengths - phew !
All that for 10 minutes ???

However not all camera bodies have built-in adjustment so the lens dock is the only solution

But you tune the lens without the body - so how does this achieve anything - I've read the Dpreview article on the USB dock - all it does it fixing the lens manufacturer - in this case Sigma - issues - nothing to do with the camera let alone YOUR specific camera body - as you known no two bodies are the same - they may be of the same make and model but they are not identical in all respect. Any way let stop here - I am not in business of buying a Sigma lens so thanks for your education.

How tuning the lens using the dock via your computer is tuning to work with your specific camera body ? unless you mount the lens on your camera to have lens + camera communication. The dock may help fixing whichever issue the lens has with all say Nikons or Canons but to your specific camera body ?

pshummer: AF speed of my Sigma 150-600 C has substantially improved after I installed the new firmware update by a Sigma dock. Nikon/Canon should follow the Sigma's idea. The Sigma dock is such a huge time saver.

@ Edgar_in_Indy
As I look at my Nikon it says
A 1.10
B 1.10
L 1.09

I assume L is the lens firmware version so - Nikon and possibly Canon lens firmware is installed in the camera body. Sigma lens can not communicate or access this firmware that why Sigma have to store that on their lens and update via their own propriety lens dock.

On article Flickr makes Auto-Uploadr tool a Pro-account exclusive (97 comments in total)

They have to stop it because the silly feature clogs up their servers with millions of junk photos - photos that I would never intentionally upload.
An average Flickr user would only upload on average a few hundred photos a week - with the auto upload that became few hundred a day - anything you click, any photo you get sent to end up on Flickr - the last time I looked I had thousand photos in my Auto upload - photos that I would never upload - but I don't have time to delete so they stay there for the time being.

mais51: Don't really like the tire marks - but that just me - the photo is great

One may as well throw out Photoshop and other images making/correcting software - if one only accepts what one get through the camera lenses - a photographer is not a photo taker but a photo maker. I notice a few people scored it well below the perfect score of 5 - for the record I did not vote or participate in this completion.
