I wouldn't call it a ring flash unless you are focusing about 2mm in front of it.
Why don't they move the flash as far from the lens as possible, perhaps either side of the lens at the edge.

On article Cokin launches vintage-styled Riviera Classic tripod (92 comments in total)

I wonder will any of the tripod designers of the 1960's and '70s be alive and realize that someone has recognised their work as classic, rather than just functional, which is probably what they were aiming for.
It must be funny to wake up and see your old work being copied 30 or 40 years later.
I hope one or two of them see this.

I would have called it solarisation rather than blackbaord.

Those are fantastic photos.
Who needs 20 Mpix when you have talent like that.

I worked in Metz in Germany a few years ago (installing a machine).
They were good people, making good devices.
I bought some flashguns ( a small one and a large Af-1 one).
It is nice to see that high tech can still be made by people earning a decent living.

Sounds very useful.
As they say, cameras compress at too high a level for most tasks.
I can see uses for it.
I will certainly try it.

a; I cannot see the point of a 1/20,000 second shutter speed - at all.
How many people want photos of a wet dog shaking itself ? or a girl swirling her hair ? Leave it at 1/2000 and ship some images of the above.

b: A companion camera with no zoom lens ?????
To me, that makes no sense. Surely the main point of a companion camera is the zoom. You can already get F1.8 on phone cameras.

c: maybe they could make 2 versions:
An F2.8 3:1 zoom one and a F1.8 fixed focus one.
or a version with both lenses and a sliding sensor that can switch between them.

It would be a lot of use as a machine vision sensor rather than a photography one. I wonder would it have applications in self driving cars ?

On article Opinion: Canon EOS 750D and 760D (316 comments in total)

It is about giving as many options at as many price points as possible for the minimum amount of extra engineering.
The innovation is the 24 Mpix sensor, which is available in 2 different bodies at prices $100 apart.
You don't have to get angry about it, just buy the one which best suits your budget.

a: No-one drives around at night with their lights off - they drive around with them on.
Thus, you do not need this capability for automotive applications.

b: The image quality at +72db of gain is fairly awful - but what would you expect with +72 db gain in an image.

c: I think the news is the ability to do +72db if gain at all, or to get usefully clean images with (say) +36 db gain.

As far as I can see, this is about 2x as sensitive as normal sensors.

Which is something, but not driving cars around at night with the lights off.

On article Olympus shows camera module concept (65 comments in total)

It is like an industrial camera, but 4.3" and from Olympus.
So it should be excellent, excellent indeed.

I hope it is affordable and has a simple SDK with all the basic functions implemented first.

(Shutter speed, focus, auto focus, aperture, ISO, single / multi snaps, video of various formats and speeds).

Forget the hdr and the art modes etc.

(Do them when the rest is solid)

Fantastic!

On article Canon launches EOS 60Da DSLR for astrophotography (229 comments in total)

Why don't camera companies make the occasional monochrome camera - no bayer filter, no quarter wave plate, just very sensitive, very sharp images.

It would be very specialist and would sell in small-medium numbers, but if you can build an astro version, you should be able to build a mono version.

Apart from the different software/firmware, can anyone think of a reason ?

Canon sell so many 60Ds and 600Ds, they should be able to run a few mono versions.
