On article Nokia Lumia 1020 becomes a tool in medical research (12 comments in total)

sooo, any marketing analysts have any ideas what sells a camera (phone)?

Guess pretty soon if not yet, connected mobile device will take more pictures than any dedicated camera system.

Any guesstimate when a cellphone camera will be use for space mission, or may be in mission to mars (so you can always call home while make selfie on mars for you social network profile pict)?

On article DxOMark recommends best lenses for the Nikon D800E (73 comments in total)

How on earth they could get 36mp image out of 36mp sensor?
What about bayer CFA, and problems with microlenses design on the very farthest corner I suppose can't really get a properly perpendicular light streams towards the sensor, not forgetting physics of light fall-off.

Or maybe the lens design is so good that it actually fit to handle medium format imaging area and being used as "cropped" on FX sized sensor?

budi0251: Congrats to Tokina for embracing the tech.
In the past, most of Tokina AF lenses for Nikon would omit internal autofocus motor and rely on Nikon DSLR motor-pin screw drive AF.

Nevertheless, I love that decision, maybe DSLR body AF motor coupling sounds outdated, but I guess there'd be less chance that AF motor in you lenses could go bad.

Sure DSLR body AF motor could go bad as well, but in case of Nikon, usually would take ages. My D1x (about a decade old) could still drive those big 80-200/2.8 AF lenses no problem, heck, I could even feel it's momentum torque during AF.

and should you DSLR body AF motor go bad, then it's time to upgrade :D
I've been waiting for that to happen on my D1x, sigh, still have to wait some more time I guess.

Dirk Nuary: So much money for that 1 inch ILC? Nooooo... So many APSC ILC that give you cheaper yet better image.

How good is Sony A3000?
Besides crappy lcd & evf?

On article Nikon D3300 Review (252 comments in total)

Wondering what lens did they use for studio image quality test, it doesn't show.
However it seems so badly out of focus, ie. same 24MP without AA filter Nikon D7100 does produce wayyy much sharper picture (RAW).

1 CrossType PDAF? I suppose they should use same lenses across Nikon crop model with LiveView AF shouldn't they?

On article Sony Cyber-shot DSC-RX10 Review (503 comments in total)

hmmm, I think we got some misfocus here.
comparing RAW image quality against Sony NEX-6 @ ISO 100 & 125, I see softer images on RX10's sample vs NEX-6.
However when you increase to ISO 200 (RX10 refocus), you can clearly see that the RX10 cropped picture sharpness is wayyy much better, comparable to those of NEX-6 (apart from the noise performance).

Could DPReview update the studio test shot for RAW @ ISO 100 & 125 for the RX10?

On article Windows XP is dead. Long live Windows XP 'Bliss' (119 comments in total)

Still use WinXP on my Thinkpad R52 (Pentium m 1.8Ghz + 2GB DDR2), mainly because I can't get proper drivers for its display adapter in Win7.

And then some,

I use WinXP SP3 32bit for my desktop PC (AMD X2 3Ghz w/ 4GB of RAM) too.
Indeed I lost about half gigabyte of RAM.

Why is that?

Well, I do love simple UI and it simply works for me, to make or change file association, file search features, drivers, etc.
Currently most of the time the machine would run Photoshop CS6 with latest compatible ACR & DNG converter. I have no problem (yet) with latest DSLR Raw files.

Then some office stuff & web browser (Firefox), media player classic, and... that's it I think my main use of PC.

Dunno if in the future they would force people to use Photoshop CC or Lightroom 5 in order to open latest future RAW files, then I might upgrade to Win 8.1

On article Prototype battery fully charges in under 30 seconds (66 comments in total)

well, just in case, probably, if such battery tech would exist in the future; then I suppose we'd find such "Commercial Battery Charging Station" just like today's gas station.

10 cent per-30second-charging @ 5VDC/200amps :D
you could even pay using your phone credit, plus insured against battery explosion, injuries, death and gadget caught fire.

to be competitive, i wonder, any of nikon 1 systems that support external flash sync speed up to 1/16000 a'la D1 series? or any early nikon's electronic shutter 6MP dslr (D70, D70s, D50, D40).

Really longing for such features, none of current dslr crop support anything higher than 1/320s sync speed (unless you buy hss support flash, and that can be quite costly and none available with monolight).

I love to use my 50/1.4 wide open in the bright daylight for that bokeh, yet not want wasting battery on my flash with ND filter.
Heck, even using my old cheap manual flash, i could control it from D1x, just set SS to 1/8000 - 1/16000 for FEC :D

On article Sony Cyber-shot DSC-RX10 Review (503 comments in total)

I suppose the advantage of DSLR is the capability of using different specialized lenses; ie. :

macro/supermacro w/ bellows or microscope lenses
UWA (sigma 8-16, or Nikon 14-24 FF lens,)
fisheye (Canon 8-16 FE comes to mind)
Tilt-Shift (Canon) or PC (Nikon) lens for super DOF focus
superfast/superbright (f/1.4, f/1.2, f/0.95, f/0.75, etc. or Nikon 200mm f/2)
fast & bright super tele (albeit very heavy 600mm f/4 or 800mm f/5.6)
telescope mounting/astrophotography
infrared imaging (need to modify the thing though)
veryfast PDAF (though sometimes not 100% accurate, useful for news PJ)

Other than that (one might add some more), I suppose Sony's RX10 is good enough for most of the time as above DSLR companion lenses system.

SuperCCD anyone?

24MP or 36MP FX SuperCCD sensor would (supposedly) yield a very good image at least 12MP/18MP.
Plus with modern tech advancement, one could get expanded dynamic range in Video!

I'd love to see those D800E sensor being halved to produce 18MP image with better noise performance (S = standard larger & more sensitive pixel) and combined with another 18MP image with better highlight (R = Reduced pixel to handle those extra 2 or 3 stops more highlight).

Get (or develop) faster processor, and you might get away with that process in Video (1080, 60p).

Hopefully we could get 16-stops of DR at 8 or 9 stops above middle gray :D
(15-stops DR would be good enough as long as we could get those "film look" highlight shoulder).

In reply to:

nicolaiecostel: First of all, this is a great entry level camera. Imagine the IQ you can get with that Sony 24 MP with no low pass. Incredible ..
Also, 5 FPS at 24 MP in a 500$ camera ? Jeez ! My D700 does 5.5 at 12 MP and the standard battery. This really puts things into perspective.
Stop requesting higher end features like dedicated ISO buttons, focus motors (what screw driven lenses you would need nowadays anyway ?!), there are higher end bodies for that ..
This is a camera dedicated to soccer moms everywhere, and newbies, and for that purpose, it will be great value.
I have owned the D3100 and while it might not be the greatest camera ever, coupled with the 50 1.4G it gave me some stunning images. Whenever your picture suck, take into consideration the following:
1. Personal skill
2. Light and lighting
3. Lens used
4. Digital processing
Yeah, I also saw that guy dismissing this because the 1Dx, ridiculous stuff people say on the internet !!

Well, but it is good for people to "feel" that they "may" need those 24 megapixels :D
And for sure you can find resources from "trusted sources" that 24mp without AA would indeed sharper than one with lowpass filter :p ; now, how can this be a bad thing? you can get 2TB HDD for 100 bucks, and most PC now have gigs of RAMs & multiple CPUs and don't forget those high speed internet too.

Hence, 24MP taken with Kit Lens and bad techniques would be just another JPEGs filling one's limitless HDD viewed at 2MP at most common Full HD monitor consumer display.

Indeed, 24 MP would also drive the sales of those 4K & 8K displays, otherwise who'd buy them?? :)

As for professional use of 24MP?
can we expect those 22MP digital backs to come down in price, considering now it has been "outgunned" in Megapixel race by a cheap entry level DSLR ? :p

Now

As I read this, I got in my hand a 6000+ US$ DSLR (Body Only) from the beginning of Millennium (guess what, Nikon D1x).
Today, functional Nikon D1x would cost around 100US$, still quite good though, you get metering with Ai lenses, vertical grip, 1/16000s shutter speed, flash sync at any speed.
Modify it to use Lithium Ion Battery and you're good to go.

Wonder what would people think in the next decade (2024?) when they're holding their 8000+ US$ Nikon D3x :)

Prolly medium format would drop in price, while we have 54MP full frame sensor in the market.

On article In photos: Flowing fins of Siamese fighting fish (28 comments in total)

Naturally Siamese fighting Fish (a.k.a. "Cupang") already having gorgeous colors, especially when they're ready for mating (male).
Mine one having almost like "oversaturated" look color.

For me, simply clean the side glass of the aquarium, remember any single spot will be noticeable.
I'd put some simple manual flash (YN-460II), set to proper power & simple slave, lay it on top of the glass cover shooting downward.
Then DSLR (Nikon D70s w/ built-in flash use for trigger only, so minimum power; had no problem with reflection as long as angled properly) coupled with 50/1.8D + Raynox DCR-250.

last but not least, lots of patient but mostly they're quite calm and the flash shooting directly at them seems like doesn't startled them at all.
