Sebastian K: I think I know where the problem is coming from. I played around with my e-m10 + 20/1.7, and sure enough, banding at ISO 400 and above. But only with the autofocus on.
The moment you switch to manual focus the banding is gone.
So I think it's the AF motor of the lens electrically (RF) interfering with the off-sensor amp of the camera. The higher the amp is turned up (higher ISO in photographer speak), the worse the influence of this interference.
That may mean there is no fix. I assigned MF to Fn1 so I can prefocus and the switch to MF. Not great, and very annoying since the 20/1.7 is one of the best overall m43 lenses. Light, bright, short, sharp (well, in the center).

The autofocus motor works before, not during exposure. The lens focus motor still works even in MF mode. There is no other way of adjusing focus. These lenses have not direct, physical control of focus. What you experience is most probably a seemingly random variation in the banding. It's hard to find a pattern and a trigger, I've done that as well. Some people think it has to do with "warming up" something. But sometimes you just can't tell why it's here, and then not here. One thing is constant though, closing down the aperture affects banding, usually making it worse, maybe due to the extra current draw that it requires.

On Canon PowerShot G5 Review preview (4 comments in total)

Used this like 10 years ago. It looks kinda cool, the size is nice, the lens is nice. It's horribly noisy (optically) at "higher" iso. Back then it was good/ok low-light performance for a digital, but we've come a long way!

Interestingness: Sorry to hi-jack this post on what looks to be a wonderful mkII camera but this is relevant...

A recent post on Steve Huff's site will hopefully shut up some of these annoying Sony fanboi's. As a m4/3's user I'm really impressed with how the EM1 did and even as someone who will NEVER own a Sony branded cam, I have to say how disappointing the A7s did overall. If I dropped $2400.- (CDN pricing) on that thing I'd be rushing back for a full refund!

PS - The 1st person who comes up with a NOT-A-SONY sticker for my camera has a customer right here - shut up and take my money!

"I am anti-Sony because I believe a LOT of the commentators are just paid employee's of Sony to talk up the camera."
Like Olympus would never ever do that.

On Sony a6000 Review preview (835 comments in total)
In reply to:

Rspivack: Just bought the A6000 and want to try shooting some video in addition to stills.

I have never shot video before on a real camera (only camera phones), so I 'm wondering which video mode is the "best"?

For maximum quality, is there any reason not to simply choose the 60p "highest quality" mode?

Why would one choose a 24p mode? I read somewhere that 24p is the same as traditional film frame rates, but does that matter?

I'd recommend you experience with various modes. See how rolling shutter is in various modes. Rolling shutter an make a shaky video uncomfortable to watch. Usually there is less rolling shutter at higher framerates.

On Lytro Light Field Camera preview (7 comments in total)

Interesting for street photography. Despite autofocus getting faster and faster, not having to focus at all still beats that.

On Studio Test Scene article (59 comments in total)

The Phaseone has different colors than all other samples. The Phaseone images look a bit more pinkish. All other cameras look greenish (even when using only RAW) to various levels. It seems that the GH4 is pretty close to the Phaseone. I have to say I prefer the pinkish tones and they feel more realistic in this particular case, but what am I supposed to think about this?
How did you process the Phaseone image, as opposed to other cameras? This will help me understand. I am interested in color accuracy.

In reply to:

Mentt: Hello, can you help me with deciding between FujiFilm X-E1 and Canon 600D with set lenses? Size and weight is no concern. Which camera has better image quality and which one is more versatile ?

These are two very different cameras, regarding size, viefinder, and other things. Depends on what you need, and it's best to try them these reviews will cover specifications but quite often what matters to you might not be mentioned in reviews.

MarshallG, how can you say that they're placed on public display for the world to see and they are preserved for all the world, when, most probably 3/4, if not more (according to my estimation), of the world cannot afford to pay a visit to the UK, nor would be granted a visa. How does that work?

Jack Simpson: :D …. indeed, I find fisheye lenses much more fun :D

This is not a fisheye lens as it does not exhibit fisheye distortion. It is an ultra-wide (but non-fisheye) lens

Rolfens: I have also found olympus cameras in general, to also be the kind of cameras that would be happy to make you miss your shot due to a bug or idiosyncrasy in the firmware of which you were not aware.

Yes they are fine, fun cameras in some aspects, and I can perfectly understand how people buy and appreciate them, although sometimes I feel that the rave and hype is undeserved.
For me it's big deal, how the interface is implemented.
I'm not coming from Nikon, or from anywhere else. I shot with a Canon EOS-50 35mm film SLR for years, then for a intermediary period with what I could get my hands on, which meant an iPhone, most of the time. These cameras had few features, and very simple, yet elegant interfaces.
No surprizes there. What little these cameras did, they did it in a predictable and straight to the point way (except maybe for the iPhone sometimes locking up).
When I finally caught up with modern digital photography, I was disappointed to see that features were added, specs were greatly improved, but little attention seems to be given to refining the interface.
There is no use for advanced hardware if you cannot interface properly with it, in an enjoyable process!

To all those who say this is a stupid post: he has a point although maybe not conveyed in the nicest fashion. Have you ever been to the British Museum?

On Lytro sheds jobs as it shifts focus to video article (506 comments in total)

It makes sense. When looking at the lytro, beyond the hype, and the looks, one is struck by two things: the price, and the total lack of video capabilities.
The price obstacle alone can be surmountable, but put it next to the lack of video, and pretty much nobody, is going to buy this camera.
And yes, pulling focus in post video is much more interesting than what it does now.

On Fujifilm X100S Review preview (492 comments in total)

Sony now offer auto iso WITH exposure compensation in manual mode, at least on their a6000. I've also read that Canon and Nikon do that on some of their cameras. The wording in the last paragraph of page 6 here partly implies that you can only get that on Pentax cameras, which is not true (anymore?). Anyway Pentax deserve mention for having implemented that AT LEAST as far back as 2007. We're in 2014 and still complaining about the lack of Exp Comp in M/aISO on Olympus, Panasonic, Fuji, and others.

In reply to:

Corhof: I'm considering upgrading from the mark I mainly because the rolling shutter in the Mark I makes video almost useless. Can anyone comment on the whether this improved from the original OMD EM-5?

mpgxsvcd, It's called a "whip pan" I think, and some directors like to use it. Besides, rolling shutter can cause a bad feeling, even if it's not blatantly visible.
It also depends on the capture format, GH4 has less rolling shutter effect when in 1080, 60p, I think.

In reply to:

Orcker: As an E-M5 and E-M1 owner I am really impressed with the features of the new E-M5 MKII. What I have noticed with a lot of the IQ comparisons so far is that Olympus just doesn't have a prime lens that actually does the image quality comparison on DPReview any justice in a sense. E.g., the 40MP comparison shots : the E-M5MkII uses the 45mm f1.8 lens and the D810 uses the 85mm 1.4G. Whilst the 45mm 1.8 Olympus is excellent for the money, it's in no way a super performance lens like the 85mm 1.4G Nikkor which has far better contrast and micro details. I happen to also own the D800 and this very Nikon lens. So the bottom line is I reckon that anyone who is judging the quality of the 40MP comparison shots here are not seeing the best from this rather amazing hi-res mode. Perhaps DPReview can retest using the M.Zuiko 40-150mm PRO instead and update this section. I bloody well wish that Oly will make a much faster PRO range 45mm or 50mm like an F1.0 or 1.2 lens.

There are 0.95 MFT lenses, but you probably know that.
Maybe AF and super wide apertures don't go well together.

I think any fanboys would not be worth loosing your temper on. It just sounds like infantile behavior. Brands have a reputation. Some brands do some things better then others. Definitely! But nobody needs to be a fanboy and make it their fight.
