dingenus: @Great Bustard and others, I know the theory. But that is about the sensor dimensions. And that FF 4x has the surface of a 43 sensor. But that is irrelevant here. This message is about the lens. And the lens is and remains an F4.5 or F5.6 lens. This is important because this is also relevant when it comes to the AF and size. That the system sensor has in theory 2 stops less good s / r ratio is also irrelevant. You buy a lens for a type of system and not an equivalent of an other type of system. Suppose we always name FF lenses after their MF eq. That would not make any sense at all.

Buy the lens for the type of an image it will deliver, rather.

"opengl 3.3 and later is required for this application to run" - not worth the effort.

(unknown member): Nikon users... Welcome to the past... You are now free to enjoy from the technological advantages that first mirrorless users started to enjoy 10 years ago. You will be more free, more creative, get better results and enjoy more of the photography.

*sad thing is that it took so long for you to get there...

Yup, like you do (enjoy the photography). Great pictures too. Just don't forget to give the credits to the photographers whose pictures you post (as proof that your system is better).

Is it only me that notice cameras are getting bigger even when the sensor is not the largest. The latest example was Panasonic, now it is Fuji. Do the camera makers realize (finally) that small is just not cool in hand?

Very nice looking camera though.

On article Sigma announces full-frame 14-24mm F2.8 DG HSM Art lens (230 comments in total)

This would be the lens to have if I did not have Nikon 14-24/2.8 that I have had for some time now. Have few other Art lenses in my collection, they are absolutely great optics. And good for Sigma, they are not about to disappear.

Quite a large camera for such a small imager inside. Not that I like smaller camera though.

Checat: I never bought m4/3 camera, but I always liked the idea of a small and reasonably priced camera system.

This camera on paper has great features, but… Low light/autofocus are very important aspects of “serious” gear, so who will choose it over D750, 6DMII or D500 (cameras in the same price point (!?!)?

It looks like a bit rushed approach to mimic A9, but Sony created first FF stacked sensor with fully working e-shutter, no blackout EVF and best ever autofocus system in mirrorless camera so it was/is special. After excellent GH5 I was expecting something a lot better than this from Panasonic.

@Petar Veliki - you lose only if you *need* those pixels. You do not lose pixels if you aim and shoot at the framing you have chosen.

@Tommi K1 You benefit from the height if you need that height. Otherwise why just not zoom at it?

If 4:3 is easier to compose? - I don't know about that, depends on what you are composing I suppose. If you do not want too much of the floor or a ceiling in the frame then 4:3 is actually not the best format to use for such framing.

As to the 3:2 ratio, it is here and it is used throughout. Here in Europe you can buy frames for either, there is no preference to one over the other.

In reply to:

Sergey_Green: Wow! The worst I have seen! And not like there is a strong contrast for where the lens would be prone to flares. Although flares show later in the gallery, rather pronounced by comparison as well. These are rather unusual amounts of imperfection for such, as Olympus presents it to be, a lens.

So they must be providing some software hack that fixes it immediately. But then what about the real purple color, does it disappear after such a 'fix' as well? Or how does the software decide it?

@Great Bustard
It is amusing to no end what people post sometimes, is not it? :-)

@Triplet Perar
"it is the nature of optics" - does it mean *all* lenses do it? I am pretty sure none of my f1.4 lenses show such aberrations, if at all.

Jan Chelminski: DPR, the Adobe software is AWFUL with Olympus files. Olympus should not be held responsible for such results from the use of such poor software. The CA(?) so visible in sample PC060349.ORF, all but disappears simply by opening it in the Olympus Viewer 3 software, which Olympus provides at no charge to its users. Colors, IMO, are dramatically improved as well. Based on the above, my assumption is that updates to OV3, Capture One Pro, and maybe even Photoshop(?), and minor PP, will effectively eliminate whats appears to be a bad case of very poor software compatibility. Please correct, thank you. 🙂
Jan

Same goes for Nikon, I have personally always preferred Capture NX-D for all the processing. But flares and fringing is something different, and that usually stays if it is in the image from the start.

I just wonder, if you say the purple disappears from the image as soon as you open it in the Olympus viewer, but what about the real purple color?Does it also disappear in the viewer, or does the software have some way of knowing what to remove and what to let stay? Kind of a tricky task methinks. And what does it replace those purples with, gray?

Images from closer distance do look nice. From a bit further it's a stretch. In other words, 90 mm 2.4 is almost there, but not quite.

On article Throwback Thursday: when studio lenses retire (202 comments in total)
In reply to:

Sergey_Green: Had this lens a while back, was pretty good for what it was, I thought. It does not produce that tightly sharp images wide open as Sigma Art does, but Nikon does add that certain character to the image (as many lenses from that period do), that can be quite attractive just as well. And it is way smaller (several times in fact) than the 50mm Art lens. Certainly worth having, and they do not cost much.

Character is oftentimes more desirable than the perfection. For example, lenses that resolve almost the same; Sigma Art and Zeiss. Later is more expensive, all manual, and often exhibits quite visible CA. Yet it is that color rendition, with CA included, that many people seek (and not only the ability to resolve).

In reply to:

badi: "This has two direct benefits: firstly it provides images with full color resolution, [...] Secondly, as a result of sampling the same point four times, the images will have greatly improved noise characteristics. The other benefits over the Olympus system is that it could be faster, as it only requires four exposures, rather than eight"

About the first two benefits... yes, they are true, but they are also true for olympus. Maybe you just rephrase, so that should be clear. The term "the other benefits over the olympus system" suggest that also the first two are "better" in pentax.

About the last one - it's not a benefit, it's a different approach - some will prefer the increased res, as taking 4 shots or 8 is usually about the same thing: it can only be applied to perfect static subjects.
Also here, i would rather say that both manufacturers just didn't want to go the full way and make both options available. At least in the case of olympus it's clearly only a matter of software.

I would expect 4 frames to take less than a second. It takes less than a second on Sigma Merrills, and those are not fast by any comparison.

Re. the size of the files. In hi-res mode M5-ii produce almost 100MB files. Nikon D810 in comparison is only74MP, according to this,

http://www.dpreview.com/reviews/olympus-om-d-e-m5-ii/9

Yes, Olympus should have implemented it both ways, but they did not.

Increasing resolution usually means unceasing the size of the frame, and size of the file - hardly a benefit in quite many cases. Adding a second to a second plus half time for it limits the usage quite dramatically. Overcoming color limitations of the bayer sensor, on the other hand, within fraction of a second is quite a different story, and it can only be beneficial to have in the majority of scenarios. Look at it this way; you can do it Olympus way - limiting, or you can do it Pentax way - beneficial. Quite not the same, is it?

On article Nikon releases ViewNX-i image browsing software (109 comments in total)

Clicking on Edit opens Capture NX-D, but does not open (nor highlights) the image that was clicked on. Adding a star to the image in ViewNXi does not show that star in Capture NX-D. I guess you get what you pay for, but I still have that lingering question - what is this software for?
