Najinsky: Very poor gallery.

First, it's an 18-150 lens, yet only two shots are over 50mm; one at 62/f11 and one at 150/f9.

The 150 f9 shot has nothing in sharp focus, is this a photographer choice or is the lens really that soft at 150 f/9? If it's really that soft there is no point having the lens go to 150 as an upsampled 100mm would look better. Well, that could be the case for this type of zoom, but in this case we have to guess because there is no 100mm shot, or 80mm, or 135mm, etc.

Also, to keep lenses compact and easier to design, software corrections are allowed for. This happens automatically during raw conversion for many cameras. For example, M43 images carry image correction data in the image file which is applied automatically by most major converters. How does it work with EOS-M, as some of these images would clearly benefit from some basic CA and diffraction compensation.

Guys, you know I love you, but I find this content quite sub-par on several levels.

@Najinksy: the small aperture shots were camera's choice, not photographers choice. We were hoping to add some telephoto shots this weekend but the weather has not been cooperative.

M02: Nice pics. I have an M5 and I’m really interested in this lens. The image quality looks good. The only criticism I have is the significant amount of chromatic aberration, but I see this clears up nicely in DPP. But I’m a bit puzzled by the fact that none of these pics are taken at maximum aperture, and hardly any in the upper half of the zoom range. The extra zoom range is the main appeal over the 18-55, and with such a slow lens you are going to be shooting wide open much of the time. Oh well, still encouraging results for a super zoom. I'm probably going to get one.

Telephoto shots are coming... thanks for your patience!

Jorginho: Sensor res is wrong in your list. Not 4188 x 3888 for sure.

Fixed, thanks for catching that.

justmeMN: "in the US in early February for a body-only price of $549" -DPR

In my experience, taking photos without a lens produces poor results.

It does indeed come with the 12-32 for the $549 price.

We've received conflicting info about whether or not it comes with a lens. Stay tuned.

WGChsv: I wonder if the two planned firmware updates will be free? In the past large updates (addition of V-Log) have run about $99.

I believe they will be. V-Log L remains $99.

TheClueless: Wut, Apple put some blond hair on the actual pioneer of modern digital cameras, the QV-10 and called it the Quicktake 200 3 years later. If you're a digital camera blog and not an Apple fanboi blog, get your facts right.

The QuickTake 100 preceded the QV-10 by about a year. The QV-10 was, however, the first consumer camera to have live view.

120 to 35: Not the best image quality by 2006 standards but it captured fond memories. I refer to "RIP Zoe, 2005-2014" caption on one of the photos.

Yeah, I added that since the anniversary of her passing is this weekend. Cancer sucks.

TBLF: Still have mine on the shelf for nostalgia, sticky grips and all! 😎

This was my first positive experience with digital coming from a lifetime of film. Before the E10, back when kodak/fuji/nikon was showing joint venture , $10,000 dollar VGA resolution DSLR's at trade shows, I thought digital was a joke and would never threaten film.

This little camera was the first digital I picked up and thought, hey, they are catching up, and maybe they will surpass film some day. The lens is actually very very good.

I take it off the shelf every now and then and stick batteries in it just to remind myself how far we have come. This thing is pretty slow by todays standards, and man, that lcd is tiny, but it still takes a respectable small snapshot and everything works like new except for the sticky grips.

If anyone knows how to un-stick the grip I'd love to hear it. Tried 70% isopropyl alcohol which didn't do anything.

Ha, thanks for that!

m1testit: Hi,

does anyone know if the "bike test" using C-AF + TR was made with a tripod?

As far as I know the E-M1 always had problems with the motion of the camera in C-AF + TRACKING mode because the IS cannot distinguish between a moving object and the "moving" camera.

Regards
m1testit

@m1testit: these are always taken on a tripod.

In reply to:

whumber: Two errors on the first page

1. E-M1 II only does 15 fps with mechanical shutter when the AF and AE are locked. It does 10 fps with AE/AF just like the D500. Maybe not an error per se, but misleading. Also, the E-M1 does 9 fps with mechanical shutter with AF-C, 6.5 fps with EFCS and AF-C.

2. Effective magnification for the E-M1 & E-M1II EVF is 0.74x, not 0.65x.

Thanks for the correction. Where are you seeing the 9 fps number for the E-M1? I can't seem to find it in any official documentation.

Thanks,
Jeff

RadPhoto: "Not only is the battery capacity increased by 37% (and CIPA rating has jumped from 350 to 440 shots from the E-M1 to the E-M1 II), but the new charger will recharge the battery in 50% less time as well."

Sony? Are you listening?

It's a MUCH larger battery. Not sure it would fit in anything in Sony's current line-up, save for the a99 II.

FuhTeng: I'm looking forward to the D500 to EM1 II comparison tests. And comparing the EM1 II to the XT2 and GH5 and a6500, but mainly, the D500 versus EM1 II.

@FuhTeng, you saw this I assume:

In reply to:

(unknown member): From examples I've seen rolling shutter is near non-existent. I look forward to more tests on this. With no noticeable rolling shutter under most circumstances, the 18 FPS and 60 FPS become viable tools.
The pro capture option is something I've dreamed about for years. With my DSLRs I was never quite fast enough to capture the exact moment I wanted.

I don't get the jealous trolling here. I've been a big fan of the challenges in this forum and seen this 'smaller' sensor beat out larger ones many times. I've seen the 1 inch sensors win too.
My guess is some people are upset and jealous that this camera does things theirs cannot. I'll settle for a little more noise and less DR, vs. no picture at all. :)

We've seen some rolling shutter at 60 fps but not any slower. We'll have an example or two in the review later this week.

wolfie: Still unable to arrange any sort of C-AF sequence test after all this time?

This is a gallery, not a review. Trust me when I say we're working hard on the review, and it will be posted as soon as possible.

In reply to:

mujana: Small mistake in the "title" / first sentence between the headlines of the Fuji X-T2. It's not a 16,3 MP sensor, I pressume (but 24MP as it says correctly later on).

Fixed, thanks.

On article Olympus E-M1 Mark II Iceland sample gallery (83 comments in total)

Hi all, we got ahold of a beta of ACR and I reconverted the Raw images that were in the gallery with it. There's definitely a big improvement over in-camera and Olympus Viewer 3. Thanks for your patience.

Link | Posted on Nov 7, 2016 at 01:27 UTC as 4th comment

Hi all, Olympus Viewer 3 arrived today so I've reprocessed a few of the Raws, including the horse image above. Once we get ACR support I will go through them again.

jonf123: That is a very uninspiring photo gallery to show off the camera. I was in Iceland back in mid-September and got far better shots with an 80D. And I'm basically nothing more than a good amateur. I don't know if I can blame the photographer or the camera for this one. $2000 for this is crazy though.

pkvman13 is correct. I wasn't about to jump a barb-wire fence to get closer.
