On Nikon debuts lighter 18-300mm F3.5-6.3 to DX lens lineup news story (67 comments in total)

raztec: Way to go Nikon. Keep sinking to the bottom of the consumer barrel. While Sigma puts out a constant f1.8 18-35mm zoom you keep sinking lower and lower into the depths of hyperzoom despair. Soon you will be the laughing stock of all photography.

If very small, light and very very cheap, and with enough sharpness, I'd buy an f8 (ok, maybe f8 is too much, something around f5.6 constant would be fine) zoom, for morning, plenty of light, casual photo without need of speed or small depth of field.

rfsIII: What they need to do is combine this technology with the Lytro approach and then you would really have something—awesome color and adjustable focus....next step: the ability to take photos in any point along the temporal stream.

Lytro or refocus is useless if you have a depth of field equivalent to a 28mm f16 FF lens.....
What do you want to refocus? Everything is in focus!

alexpaynter: I cannot find any mention of sensor size. Does anyone know what it is. The lens sticks out a bit so I am guessing it may be 1/2.3 inches like the Xperia Z2.

I don't really care about the looks as anything I buy will be put in a cover. The replaceable battery is a big plus for me.

I have a nexus 4 at the moment and it downloads youtube extremely slowly. Much more slowly than my old iPhone 4. Is there a reason a google product can not download another google product? I am concerned about buying another Android product.

Pixel size is 1.12 micron, so i did the math with the 16 mpx resolution and came out a sensor of 6x3.3mm. Less of 20mmq of area, it is actually nearer to a 1/2.7"type sensor.

RichRMA: The most interesting thing by far is the back side illuminated sensor. No one has one this big, they've been confined to tiny sensor P&S.

The biggest BSI CMOS today is the 1" of Sony RX100 II.

Why can't we compare cellphones to other cameras? Tool is the same, why not?
It could be very useful to see how much gap remain between phone and compact cameras.

TheProv: Nikon D7100 JPG ISO 12800 is MISSING

I reply myself: it's not missing, but it's under/past ISO 25600, so if you set ISO12800 for 70D, the tool cannot find the same for D7100.

On Nokia launches 41MP Lumia 1020 for Windows Phone 8 post (147 comments in total)
In reply to:

TheProv: I did some math.

1020: crop factor 3.93 , lens F2.4, equivalent aperture (depth of field) is F8,646

808 Crop factor 3.24, Lens F2.2, equivalent aperture (depth of field) is F7,776

Also, made 35mm area 0 stop, 1020 has -3.89 stops less, 808 -3.34. It's half a stop of difference between them.

So, i believe in ideal conditions (daylight, tripod, ISO 100), 808 will potentially still give a little better results than 1020, but accounting BSI technology and OIS, in many other situations differences will be subtle.

What you said is exactly what i wrote.... -_-

On Just posted: Olympus Body Cap Lens 15mm F8 review news story (127 comments in total)

I can accept you spend time reviewing this TOY, instead of many other real and interesting lens, but i cannot accept you say it is INEXPENSIVE, when it costs 70 €. It would be inexpensive if it costed 20 €.

In reply to:

Hugo808: So the lenses most people are going to use - 18-55, 18-135 - are the worst ones for the camera?

That makes it a tough sell, why can't we have a top performing standard zoom without having to carry around something heavy like the fast L series options?

Just once would be nice.....

Actually from what i read, except the top three standard zoom, 18-55 and 18-135 are not so far from other faster and more expensive alternatives, speaking about quality and definition.

A no sense buy. G15 canon, panasonic lx7, Olympus xz-2, nikon p7700 all has faster lenses, same or better range or both them.
On the same sensor. With smaller body.

Until pentax make ultra wide angle or extreme telephoto.... Dou you believe in it?

On Canon EF-M 11-22mm f/4-5.6 IS STM Preview preview (81 comments in total)
In reply to:

Jefftan: Sony NEX 10-18 F4 225 gram
Canon 11-22mm F4-5.6 220 gram

not as wide, not as bright and same weight

What's going on? Is this the best what Canon can do?
Can't understand

It's obvious: Canon wants to mantain low price (nex 10-18 costs 700 € this one 300 €) and size (nex 10-18 is the same weight but bigger).

It's not a stupid move.

Day Galaxy S4, night Lumia 920. End of games.

If I had to do only a name, Lumia 920. Even if in the morning light it doesn't perform well, thanks to CRAZY nokia's noise-reduction and sharpening algoritms, it's still more than adequate for web (@2mpx) and little prints.

In reply to:

Benarm: Great alternative for 17-55/2.8 lens if you're willing to trade some zoom range for more light, Nikon and Canon have been ignoring to update their fast crop lens for a awhile now.

Without 50/55mm no portraits, the only annoying thing of this wonderful lens.

On We put the HTC One's ultrapixels to the test post (172 comments in total)

About softness, maybe you have the same pre-production One that hardwarezone had. They also reported softness, and HTC send them another One , that hadn't issues, in fact it gives visibly sharper images than the old One they had.

Look at here: http://www.hardwarezone.com.sg/review-htc-ones-camera-tested-updated

On Samsung Galaxy Note II camera review post (82 comments in total)

Are you serious? Really? Are you the same of DPreview or are you stealing only the name?
It takes bravery to call this "camera review".
Even I could do this "camera review".

Please be serious and start doing cameraphone reviews at the level I can see on your mother site (?) and for wich I know you are able to.
