kff: next version would get a special AF bracketing (by moving AF point from the front to back) for fast aperture in the macro composed from several pictures when its are taking from tripod ...

Why have photographers to do it in the a special macro software and with a lot of effort during taking today?
What does Ricoh say:?)

It is need in the Petax' branch e.g. in the K-01, K-5 etc.

actually the other Ricoh's have that feature!
My old Ricoh cx1 has it, you can choose 3 or. 5 frames and smal or big distance differences.

On NHK working on 8k video sensor capable of 120fps article (101 comments in total)
In reply to:

wb2trf: But to get a decent OVF the mirror will have to move 120 times per second. That'll be hard. :-)

OR you can record at 60Fps and use 60Fps as live view.
Why would anyone even film in 120fps, exept slow motion recording?

In reply to:

win39: I normally love this type of water shot which shows details below the surface as well as above. Pretty image, but I am disturbed by enlarged scale below the surface. The diver and ladder are much to large in comparison to the man and ladder on the boat. I am disturbed by backlit and cloudy above the surface and sun bright and from another direction below the surface. I am disturbed that the ladder above and below the water are at severely different angles. Seems to me if you are going to Photoshop something like this, it should at least look real.

@candlejack: the path of the light in going from the water to the UW-case of the Canon (air) into the lense. there comes the refraction.

The aspects of optics, refractive index, magnification are about right. the angle of the leader has to be there!

but: the diver is brighter than the boat. I belive thats not possible.

They don't have to make it in Canon Mount. ;-)

In reply to:

Mssimo: How good would a 5MP sensor be with todays technology?

18Mp is quite crazy for a ultra compact. I wonder how large the images are. (13-18MB?)

My Canon EOS 7D produces 18MP files that are muche smaller, like 7-9MB depending on the subject and the ISO value.
My guess would be, that the sony files would be even smaller, because of the smaller sensor... (4-6MB)

On Ricoh GR Digital IV Preview Samples article (33 comments in total)

wonderful lens, but not so good sensor.
there is some noise at ISO 80 like a new DSLR has it at ISO 800
And ISO 3200 is not as good as a Canon S95, my opinion.

On Ricoh announces CX6 CMOS compact superzoom article (35 comments in total)
In reply to:

Ashley Pomeroy: Talking about the flash, I've always wondered why some enterprising compact camera manufacturer doesn't build it as a ring around the lens mount; it'd be a mini ring flash. 'twould go down well with hobbyists, and even if it doesn't work very well it would at least be something to put in the press release.

I have the Metz 45CL-4 for night landscape photography @ ISO 400 it will lite 25 Meter in distance!
With the DSLR it's 256 meter with ISO 6400 and 30mm F1.4
:-D
It's fired with a Photodiod on the second flash...

On Fujifilm releases X-S1 premium EXR 26X superzoom article (383 comments in total)
In reply to:

anthony mazzeri: Are the listed size dimensions correct? At 135mm(W) x 107mm(H), it makes this camera wider and higher than even a Nikon D7000.

It's almost a kilo in weight as well. A (Brooklyn) bridge camera. ;)

Well, I guess they decided to go with a bigger Sensor instead of compact body.
They could have made it smaller of course, with a smaller sensor or less bright lens...
But I like thayt they decided to make a quality product.

On Ricoh announces CX6 CMOS compact superzoom article (35 comments in total)
In reply to:

toysandme: I see no mention of it here but the main reason why I have been attracted to Ricoh cameras over the years is their (almost) unique time-lapse feature. As a matter of fact, this is the only reason why I have bought their cameras. I hope they keep this feature and make it more flexible with say, one frame a second instead of one frame per 5 seconds.

Pentax W60 Outdoor Camera has a good time-lapse feature.
But I like the Ricoh better ;-)
It has way better IQ...

In reply to:

itsastickup: The Sony system is very attractive but for one issue: none of the pro/semi-pro zoom lenses have great bokeh, and some are downright awful. Canon lenses thrash Sonys at bokeh.

I really do want to buy in to Sony but this issue is a show-stopper.

what about the 135mm F1.8?

pgphoto_ca: I don't care about the look....give me picture quality !

Sony...Nikon...Canon....have nothing like that so far !!!

you're right, canon Nikon etc. lacks a rugged camera with 170° view angle...

On Lytro Light Field Camera first look with Ren Ng article (225 comments in total)
In reply to:

Ashley Pomeroy: I sincerely hope it turns out well. I suspect it'll end up like the Wankel Rotary Engine - a niche thing, with fans - but it's nice to have a bit of diversity. I can remember when the possibilities of digital imaging seemed endless, but over time the technology seems to have homogenised, with most of the effort going into the packaging; if this could be made to shoot video the results would be beautiful.

Although I worry that the technology is too complicated to add to an existing imaging system, as a kind of added ingredient, and conversely too esoteric to capture a mass market. I wonder if it could be built into lenses, so that e.g. you could stick a 70-200mm f/2.0 Selective Focus lens on your Canon, or what-have-you?

It's 4MP... it's more than your monitor can show!

Does it go down to 1 second? then you need a tripod...
