NumberOne: ...So a brand - Sony in this case - should work and perform at 100% with other manufacturers gear?! :)
This is so pathetic - The compatibility is already an excellent gift - What do you want more?! :(

Amazing, to say the least! :)

@NumberOne. Your comment is true. It is not likely that AF will work well.

My point is only that the check DPR made was reasonable. Sony do not have the glass needed for this kind of camera, and it can use Canon glass. So - why not test? And write about it?

An actually it did work rather well at low speed. Which might be good info, and alao a surprise.

I have no clue about who buys what - so do not point at me. I am not into super sport equipment. I just mentioned for @NumberOne that his comment was a bit off.

The reason for this article - a9 is a sports monster without a sports monster lens, lets see if we can use the Canon sports monster lenses. Conclusion - nope, not really. So, what are you wining about @NumberOne ?

On photo Hot Air Balloons Over Bagan in the balloons challenge (6 comments in total)

I have seen several ballon images over Myanmar. Many has this golden hue. Did you do anything to get it? Some post processing? Some choice of image mode? Whatever? The fog hints at it being sun rise.

On challenge Angered Subjects (Street Photography) (5 comments in total)

Very strange subject. As also can be seen by the resulting images. The few that really seems angry (most do not actually) are angry at the photographer. They do not like being photographed. A bit strange to publish them in a competition then. If there is no serious and real reason. Which, I think totally is lacking here. Then this is a pure offense to the subjects. And this competition should really be removed IMHO.

On article Now we know: Sony a9 is sharper than we thought (375 comments in total)
In reply to:

Roland Karlsson: OK. So, the camera cannot really focus. Even though it focus on the actual sensor. Isn't that cute? You think it should be possible. To be fair. Other cameras probably cannot either. And this on a stationary, flat surface with lots of nice contrast. Thank you DPR for showing us this and making us getting some perspective.

Then, of course, if the scene is 3D. Or if it is moving. And you have no tripod.

Yes

"Multiple AF-S attempts yielded shots varying slightly in sharpness, but this is not unique by any means to the a9: all cameras exhibit some tolerance when it comes to critical focus of a flat chart (which is why we always manually focus)."

And I really think those "tolerances" should be possible to make small enough for this article to have been unnecessary. I guess the main issue is the accuracy of the focusing motors and mechanics.

Then, it is another story that manual focusing in the review is, kind of, misleading. I think they should do both. Just to get a measure on how sharp the camera is in normal use.

Art within nature: Would this mirror work from Amazon,

American Educational Products Mirror, Large Demonstration, Concave, Parabolic, 40.5cm Dia. X 68cm fl

Note it's parabolic not circular.

The telescope mirror is also parabolic (I hope).

Some misunderstandings here. The first and major one - this is a double exposure. No, it isn't. The second one - I could have done it in camera. No, you couldn't. The third one - I could have done it much more simple. You could maybe avoid using adjustment layers, if you think that is too complicated. But otherwise, no, not really.

Other than that, I am not all that interested in the and result. A bit strange and uninteresting. What do a wood brain pretty girl tell me? Not much.

But the way there was interesting to see.

In reply to:

WastingTime: So, are people are not buying multifunctional printers or just not buying Ricoh's printers?

My point was that this has decreased drastically the last few years. So, sure there are almost always printers in offices. But - they are not worn out.

Roland Karlsson: Hmmmm ... maybe I am imaging things. But those newly taken portraits lacks something that old portraits had. A kind of pride and authenticity and more alive and a kind of aura. The images here looks kind of boring. Not that they are bad, just that I do not get the feeling like looking at the real thing. Then - the trick of "no real whites" in the prints is kind of tiring in the long run.

I did not saying anything about challenges. I said the images showed no challenges. There is a difference.

In reply to:

walgarch: Sad news really, but I assume that's why companies diversify. If Ricoh's office equipment division isn't as profitable as it once was, perhaps they'll start investing more in their camera divisions?

I don't think this report is all doom and gloom

"In the past their lenses were amazing but their current glass is mediocre."

I am inclined to agree actually. Not maybe mediocre. But in the case of lenses, Pentax were much more interesting in the past. There is a reason for the "pentax lens review" site. Its a solid collection of lenses.

I think it is mainly - not buying printers. Why buy printers when you do not print?

wai chin: Business 101

Bad money.

Eh? What?

Ricoh's main business is office printers. They are starting to get short in demand. The paper less office it is called. Much ado about that 30 years ago. But now it is here. More and more company processes are purely digital.

sunilkumar: it is sad to see companies downsizing one by one. It puts lot of stress on employees and their families.
I have seen one downsizing myself and was able survive. Some people could not handle the stress and took extreme steps. I wish this company survives and in future all companies think before going overboard on spending and in some cases expansions.
I have a concern but it is no match to the employees who will be suffering from downsizing.

When the products you make dwindles in demand - downsizing it is. Trying to do something else is difficult. That can also anyone else do.

And in this case - the paper less office is the bane.

munro harrap: When you can buy a good 4K monitor for a lot less than you are forced to pay for a photo printer, let alone its ink , WHY print. Wake up and smell the ink Ricoh, ca pue! Keep on with the cameras though but try a GR with a viewfinder?

That is probably not the problem. Most Ricoh printers are office printers. And ... the paper less office is coming - at last. I print nothing - nada - zilch - in my office. This is, kind of, the same problems as news paper.

Mankind is a collecting species. Some will buy this.

BTW - my main tripod is a Gitzo reporter. I think I bought it 40 years ago. It is indestructible. It might well outlive this collecting species.

That was not a clean cut. It was uneven and ugly. And was the guy funny? Not!

Sorry - just had to let it out.

Lives and challenges? The photos are mainly portraits of people dressed up in their "formal" dress. Those images say nothing about challenges.
