mosc: Canon still makes a 24-105 F4 IS lens that's about the same money, am I missing something? 24 is wider than 28 and F4 105 can crop quite a bit and still compete with f6.3. Anybody?

You simply can not crop to change focal length, it's that simple. http://en.wikipedia.org/wiki/Focal_length
Sure, having a stop larger aperture at 100mm helps you get one stop cleaner image, but it's *not* the same to take (for example) an image at 105mm f/4 and ISO 800 and then crop 50% of the image than it is to take an image at 200mm f/5.6 at ISO 1600. Just read on the subject.

You can't crop to increase the focal length, regardless of aperture. However. the 24-105/4 is a good general purpose lens and the 24mm wide angle is very handy. But these two lenses are completely different animals and comparison between them is pointless.

I haven't received mine either (pre-ordered ages ago) and I don't see any updated info on their website. I'm excited about the product, though. A simple yet very useful gadgett-app combination.

Perhaps you could name the other $900 50mm auto focus lenses that compete with the Sigma 50 Art?

In reply to:

justmeMN: It's a nice camera, but it costs more than an SL1/100D or a T3i/600D.

What's infamous about the EF-S 15-85? It's one of the greatest EF-S lenses. One he** of a lens for sure. But a fact about the G1X II is that it's got a sweet lens for the size of the camera (as long as performance of the lens is adequate). If you start doing FF equivalent conversions, you might as well bring micro43 lenses and compact cameras into the comparison. I.e. trying to tell you - forget the pointless calculations and take SIZE into the equation. The G1X II is smaller than just the 15-85 lens.

These were apparently shot in JPG and it would be sensible to mention it somewhere. The images appear to show Samsung's weak handling of noise for JPG images. RAW will result in much better quality.

On Sony plans March firmware update for Alpha 7 and 7R article (120 comments in total)
In reply to:

TinyTempo: They did not fix the auto-ISO? Bummer.

Nspur: like I wrote previously, with Auto ISO, the A7 does not take into account either the 1/fl rule or brightest aperture. The camera sticks mostly to 1/60 seconds (in A/P) or f/4 (in S/P) regardless of focal length or largest aperture. This happens even with the razor-sharp-wide-open 55/1.8. That's not an "auto" feature.

A quick look at Paul's posting history reveals that he obviously can't help himself. But I hope one day will come the realisation that a fanboy-denial-attitude is not helpful.

The Auto ISO really needs an update as it does NOT work properly in any other mode besides the Manual mode.The camera does not open aperture (up to widest possible) or adjust shutter speed (to roughly the 1/focal length rule) before adjusting the ISO, it maxes out the ISO before adjusting shutter speed or aperture! Every other sensible camera on the planet does it differently (Canon, Nikon, Olympus, Panasonic, etc). He**, even on my Sony RX100 the Auto ISO works as it should, but not on the A7!

I thought the time-lapse mode is a $10 downloadable add-in and not a camera feature that can updated by firmware.

The GX1 mkII is about as thick as the smallest u43 with a pancake zoom, but the GX1II has a bigger sensor and a much faster (and wider!) lens...

In reply to:

Arn: All of the exposure modes (P/S/A) are broken with Auto ISO and even program shift doesn't work. When for example dialing a larger aperture, the camera will only increase shutter speed, it will not reduce ISO.

Shutter speed priority sticks to f/4, even with the 55/18!

Aperture priority will raise the ISO all the way to the maximum before lowering shutter speed under 1/60 with any lens or focal length!

Sony needs to fix this ASAP with a firmware update! I have this working perfectly with every other camera (even my compact cameras RX100 and Canon S95 can do this perfectly right, not to mention all my DSLRs). I don't expect to see this sort of cock ups on a camera of this level. AutoISO is one of the very best features of modern digital cameras, but somehow Sony was able to mess it up here, even though they get it right for compacts.

I'm glad your having fun, but it doesn't change the fact that Auto ISO on this camera doesn't work at all as it should. I have six other cameras with a fully working AutoISO (in fact I haven't seen a camera in years with this crappy AutoISO). But for some reason Sony messed it up here, even though they got it right with RX100 and RX100II. When I pay 2000€ for a camera (and almost another 2000€ on lenses), I expect a simple feature like this to work.

Gottschalk: This makes me realise how good my OMD is! Hold up very nicely against the competition with bigger sensors. Couple that with the speed and I don't see any reason to jump ship...

Bear in mind, that the framing of the test is to the advantage of the micro43 camera and it's aspect ratio. The sides are "cropped off", so there is less of the image there.

What do Nikon and Fuji have that looks like the A7?

In reply to:

zither: OK, everybody acknowledges the sharpness (score) is partially because of the A7R 36mp sensor. But what about A7? I think it's more fair to compare this FE 55/f1.8 on A7 with 50/f1.4 on Canon 6D and Nikon D610. They are the most popular (affordable) FF cameras + standard prime lens bundles and the overall prices are in the similar price range as well.

Yes, I too wonder what the performance would look like on the A7. Why didn't they test that?

New boyz - if you select NEX-7 and compare to Otus on the Nikon D7100, you'll see a big difference on favor of the Nikon + Otus, but on the A7R the FE 55 and Otus are about tied. So, it's not as sharp on any sensor.

On Fujifilm X-T1 First Impressions Review preview (1657 comments in total)

The greatest appeal in this camera is that it has both an EVF and a tilting LCD (the first X-series Fuji to have both I think), combined with great manual controls. I would have preferred a fully articulated LCD, but even like this the X-T1 is very tempting. Handling/controls are far superior compared to Sony NEX 6/7 cameras. The biggest negative is the price - a bit on the expensive side with the price of X-mount lenses included.

Thanks. That looks absolutely awesome. I've been waiting for more mirrorless cameras that have EVF *and* tiling LCD as I consider both indispensable (though I would much prefer a fully articulated LCF). And I was especially waiting for Fuji to bring a camera like this.
