cpt kent: Seems to be a lot of folks exclaiming brilliance without questioning. Sources? References? Research? Further reading?

Just an introduction to ETTR - if you want to know more just Google it. Modern sensor is far more forgiving than earlier version - I can pull a lot of details out of my D800 under exposed RAW file than my D300s RAW file - just a bunch noise noise. Just watch the over expose clipping however - once it get there not much you can do.

Biological_Viewfinder: I'm gonna give this camera to my little kid. I mean non-stop continuous shooting????? Even a 5yr old can get the shot now!!!

"Here kid, take this"
"It's very heavy."
"Yeah, but that's not important. Do you hear it working?"
"Yes daddy."
"It's taking pictures."
"It is?"
"Yep. Point it at those birds."
....
....
"WOW!!! THIS IS AMAZING!!!! YOU GOT THE SHOT!!!! LOOK AT THIS!!!! AMAZING!!!!"
"Thanks dad."
"No problem. You're a real photographer now. Those mean know-it-alls who frequent DPR were right; all it takes is equipment."

I first attracted to SLR back in the old film day and the brand was Pentax - just because it was cute and small - Canon and Nikon were big and ugly, over the years I learn that cute is not enough - the Pentax brand had its limitations but I continued with the brand until Pentax decided to drop the M42 lens mount. That made me look around for an alternative - my research lead me to Nikon - not only it is a famous and well loved brand, they've never changed the lens mount - the legendary F- Mount - improved it yes - abandoned it no. So here I am still shooting Nikon since 1982. In the mean time, Pentax went with the K-mount and Canon abandoned their FD to their EF and EF-S and EF-M...
Unlike Nikon, Canon lenses are not interchangeable, so if you have a EF-S lens you can not use it on a EF mount (full frame) camera whereas all Nikon lens are mountable and useable - including the Nikon 1 lens with appropriate adapters.

five5pho: unlock unlimited continuous shooting?
As a canon user kudos to Nikon!

Problem is the heat built up - suppose Nikon thinks it is now OK after extensive field testing

Sure, if you are rich enough you could give the cam to your little kid. Your comment in fact reflects on you as a photographer more than anything else.

En Trance: Finally, a manufacturer correcting shortcomings for free. Wish there were more out there.
Too bad, I do not like Nikon. Don't know why?

En Trance - I did not mean to offend you It is just that I am a bit amuse that someone would go out of their way to comment on something they don't like - I don't shoot Canon DSLR but I still read about Canon equipment. As far as Sony goes I use their video cameras and TVs but not their DSLRs or their hifi equipment - not yet anyway - I don't dislike them is just that they don't fit my need

If you hate Nikon why bother reading or commenting on Nikon equipment news

neil holmes: When DPR gets it and tests it I hope there will be a comparison with the old Canon FD 85 1.2 L which goes for around the same price in many cases.

Looks nice.

The FD is not an AF lens - this Mitakon Speedmaster 85mm f/1.2 certainty not a "Nikon-way" lens - similar to a Canon it focuses from right to left, the aperture also opens from right to left - so as a Nikon user one will have to adapt to the Canon ways.
Looking at the lens construction diagrams posted by Dr_Jon - thank you - you ill see that there not much different in the lens construction - optically - that's the law of physics I would say - for a given outcome they all have to come up with similar solutions.

falconeyes: 7000 µm pixel pitch. wow! :)

That is why the thing can only take 1 frame per sec - the rest of the 0.99 sec it uses to collect power.

Is this how they are spending their millions dollars in research - to produce a jack of all trades and good at nothing

Possibly a clone of the Canon

pca7070: I found that optical or sensor stabilisation works best at very low shutter speed.

I second this - I have problem with my 24-120F4VR at speed about 60 to 120 beyond that is OK and below that is OK - the problem is this is the Flash shutter speed zone !

bossnas: Those people fortunate enough to get their photographs replaced were only able to because they had prints in the first place. The importance of a print cannot be overemphasised. If an image is important to you, print it. Nuff said.

So is your photo album - chance that a USB or memory stick survive the great destruction are much better than the photos on your fidge door

Well if you have them stored in a memory card or USB stick then they will be recovered without fuss.

brumd: "On first use the filter needs about four hours of sunlight to create the hydrophilic characteristic"

What does that mean exactly? 4 hours of bright light on a sunny day? How long would it take on a cloudy day, for example in Iceland?
And how long does it take on second and third use?

Yes it is - it is the UV A spectrum with the violet filter to cut out visible light

I've seen them in night-club also - but is it the right frequency. Won't be too surprise if Tokina also sell you a UV lightbox costumed built to meet their filter requirements,

@Lassoni - That's a good idea - as long as we can isolate the effective UV frequency we could construct a small UV lamp box to charge the filter- that way it could be used to condition the filter overnight ready for the morning trip. Not everyone has access to ready sunlight.

Jozef M: How much weight? How big/small is this apparatus? Use the metric system too, please.

@Francis Carver - are you serious, the metric system has some logic whereas the Imperial System has none - totally arbitrary. How do you relate an inch to a foot then to a yard - just someone tossed up a set of numbers. I went through all my high school year in a metric country (MKSA - Metre, Kilogram - Second and Ampere ) then went to university in Australia doing engineering- at that time still using Imperial Units - what a struggle - pound, pound force, pound mass, slug, stone,weight, inch foot.... no rhyme or rhythm at all - I am glad that they saw the way and converted to Metric or IS since 1975. We call it International System for a good reason = universally understood.

Yxa: Why is it called Super 35 its smaller than the still 35mm
It should be called sub par 35 (that would be more true)

@ Yxa - I like your Avatar - but in using the main character of Avatar as your Avatar don't you think you may infringe their copy right, unless of course you hold copy right to the film - in which case I withdraw my comment.

Say 6% of the world population is still using the Imperial Units - apart from USA and UK I can't really see anyone else is using it. Even your neighbor Canada is very much into metric.
