yabokkie: > Another bokeh-less fast lens for m4/3.

like it or not, at the same angle of view (forget focal length), more bokeh means faster and less bokeh means slower. this is physics that no one can break.

this is because both bokeh and light collecting capability are controlled by a single factor, the aperture size (diameter or area). they just change accordingly as the aperture changes so we cannot separate them. they change exactly the same way regardless of whatever format we use.

at the same angle of view, the lens cannot be fast if there is no bokeh.

look at all the cameras from 645 to mobile phones, you can see all of them line up straight, that the depth of field is hard-wired with image quality (resulted from light collecting capability).

more depth of field, less light/more noise collected.

There are ways around it technically, using multiple images and post processing, or in camera/lens focal plane movement. or simply use more glass and open up the aperture like the latest generation of small sensor compacts.
The light gathering is more a function of sensor size all else being equal, But if say, the Canon 1.2 fifty was re-designed with rear elements to have a smaller circle you could get back the low light performance lost by sensor size considerations, Still wont get it all back though for the OOF areas though as I understand,

So there are comprises you make for a smaller system overall for travel when your main objective is business or backpacking etc, i think the MFT system is great, i don't think the lower DR and noise is significant pictorially in most circumstances
But If you want to do big OOF effects, and shoot black cats in the cellar at midnight, FF is the way to go.

forpetessake: Has Metabones set some fire to Panasonic feet? Finally, they are starting to get that people want faster lenses. The 85mm f/2.4 and 300mm f/5.6 equivalent lenses are getting closer to FF standards, provided they didn't sacrifice image quality.

Curious, How do you arrive at those equivalent F stops?

In reply to:

jnk: just curious - why would DPR provide firmware notice for the D4/users and yet - the camera has not been review?

This thread, here in a nutshell is what is wrong with the internet (people), one small informational post, and a pile of negativity follows. its like a bunch of teenagers have been collectively asked what they did at school today.

In reply to:

so: Is it just me who would love to have on such lens an automatic cap, like most compacts have? For me that would improve camera usability (by allowing one-handed operation) way more than if it was F1.4 or whatever.
Wishful thinking.
Snapping NEX pictures while on a bike. Or horse. Or while driving.
For most shots you don't really need your left hand for anything else than taking the cap off, right?

With a UV filer, take the Camera out of you pocket, and you still have to deal with a dirty lens. an integrated cap, mostly that won't be the case

Matthew Miller: "Caution: Only K-5II/K-5IIs users are permitted to download the firmware update."

So, watch out, all you Nikon and Canon users. The download police will come after you.

To late , downloaded to my Panasonic bread maker, I have to tell you its not working out

Very good review.
Latest batch of electronics and fast throughout the range zoom lenses, has effectively made a real competitor to the Mirroless uFT and APS sensor cameras, unless you plug in faster optics than a std Zoom.
In most (nearly all) circumstances I recon you would be happy with the output of either,
I wonder if we will see small sensor cameras become fashionable again with hobby photographers as a first choice camera.

attomole: Quoting Barney on the full review of the FZ200, leave me to believe DPR have either made a categorical error with its inclusion here , or its deliberately provocative choice.

By Barney Britton (4 days ago)
It's not just about IQ. A big part of the reason why the FZ200 got such a good score (and bear in mind that scoring is relative to product category, and the P7700 is in a different one) is that it has an excellent lens, is nice and quick, handles really well, and offers Raw mode.

Beach Bum. dimensionally the FZ200 is plainly the odd one out, I am in the market for a small camera to cary on business trips and the like where my SLR kit is not portable or discrete enough. all the cameras here are on that lest to consider, apart from the FZ200, nevertheless on the strength of its inclusion i did go an look at one and gave some thought as a possibility, therefore i would say "provocative" in that it provoked me to reconsider what i wanted. In the strictest sense i would concede that it is a compact zoom camera, but only just, and only in comparison to SLR's.,
The point is worthy of debate, but i am OK with the choices DPR make its there publication, Whist there is a comments section i feel quite happy to pollute it with my opinions, and will continue to do so.

@revenant, the phase
"By 'zoom compact camera', we mean cameras with non-interchangeable zoom lenses, regardless of size."

Is an oxymoron.

Nevertheless, despite my grumbling I think its a good editorial call, as it has challenged my own view of what i may actually be looking for, I went to look at one and in store and did a speed read of the full review. But decided that what I mean as compact is a jacket pocketable, discrete and folds flatfish.

The FZ200 is a compact version of an SLR and two lenses, but as Barney said in the comments section of the original review, its not in the same category as the p7700 (and the other cameras here)

In reply to:

Hubertus Bigend: I wonder why nobody seems to feel that the lack of a viewfinder is something to not like. Especially with travel zooms reaching up to 480 mm (eq.) or more, I cannot believe even half-serious telephoto shooting is possible at all; without a finder it is already improbable to even, well, /find/ a subject like, say, a bird in a tree.

If miniaturization will produce a travel zoom including a viewfinder at some point in time, that will probably be the first time I'll see myself inclined to perhaps replace my old Olympus C-70Z...

I agree, as much as the little Sony is a fantastic instrument for recording am image, I find the ergonomics horrible.

2005magnum: I am surprised that the Fujifilm X10 is not included in this group.

I think Fuji shot themselves in the foot with the orbs problem, not so much with the engineering, which I understand is fixed, but in there response, there is no way of knowing if you will get a fixed one or a faulty one, so how can DPR recommend it?

Be Nice to understand if what was excluded, like the Panasonic LK7, and Nikon p7700, was for meritorious reasons or for, well we just haven't had a good enough look at it yet to make a fair comparison.
Some publications do this sort of thing on a rolling basis like the hit parade, such that when something comes along that is better, the line up is changed to reflect that.

Nevertheless a useful list Thanks DPR.

In reply to:

IrishhAndy: Happy with my D700. This camera has too many compromises for me and the lens selection is poor.

I think they could have beefed up the sensor and processing and left the D700 pretty much as it is and made a far more attractive stills set up, even left out Movies altogether to keep the 800 as a premium option in that respect (second thoughts it may leave them taking a kicking from competitors in the feature wars)

wetsleet: "The composite image is made up of 55 high-resolution images, taken using its MAHLI [2MP CCD] camera"

So how does a 2MP camera take a high resolution image?

Your HD TV is around 2MP, so this image is equivalent to 55 HD TV cameras, Its about building an image. As an engineering solution it is entirely appropriate in the circumstance.

dbateman: Robin Wong has done an excellent "User" review of this camera. Any one interested should check it out:
http://robinwong.blogspot.com/
The High ISO on the is camera has me considering it.

Thanks, there is no better advocacy than just looking at some really great pictures, still the quality starts to fall over above 1600 ASA, but wow, so did film,

Great to hear of your new resolve to give this prime topic a shift in focus, That DXO is hand holding should also lead you to some sharper content. The frequency of your output needs to be in contrast to the past which was at best, Shaky.

I have looked far and wide for somthing along these lines, I hope this new venture put's a cap on it.

Whilst components may be similar Medical device manufacture, service, sales and post market surveillance is massively regulated business. and very different to consumer goods, Owning OLY would allow Sony a shortcut into that business and OLY the capitol to continue, Not sure on the consumer end of the business its difficult to see where that will mean anything other than a stay of execution for the Olympus brand and products

I had a 3s it was actually pleasingly bad, Fidelity does not necessarily produce great photographs.
