On Samyang announces 12mm 1:2.0 NCS CS wideangle for mirrorless news story (139 comments in total)
In reply to:

jtr27: Is this lens in addition to, or instead of, the 10mm F2.8 which was announced some time ago? To my knowledge that lens can still not actually be found, and nobody has seen one, much less tested or reviewed it.

We do love announcements Samyang, but we love actual availability of lenses even more! =)

The 10mm F2.8 was only *officially* announced [in December](http://www.dpreview.com/news/2013/12/06/samyang-announces-10mm-f2-8-manual-focus-wideangle-prime), but Samyang has clearly had more problems that usual with the design, after first showing it at Photokina 2012. More generally, Samyang has delivered all the lenses it's promised in pretty good time.

This new 12mm F2 for mirrorless is clearly a very different lens to a 10mm F2.8 for APS-C SLRs, and crucially a rather less ambitious project.

axelpix: Isn't it on the E-M10 and it's called Live Composite? It basically stacks a couple of exposures like Live Time but uses a blending technique similliar to the Photoshop Lighten blending.

No, this is distinctly different. The E-M10's 'Live Composite' compares multiple 'correct' exposures, and adds in new data to the final composite image based on a 'lighten' rule. This is more like 'Live Bulb', where you watch a long exposure build up and stop it when it's 'right'. But the difference in the new patent is that different areas of the image can be exposed for longer or shorter times in a user-definable fashion, which would allow you to cope much better with extreme dynamic range scenes.

On Am I missing something here? article (563 comments in total)
In reply to:

GRUBERND: i think the point the author and most of the commenters are missing:

this camera was not built for you.

not for your use-cases, not for your demographic, not for your culture, not even for your country. drop some expectations and biases how a camera is supposedly to work or be used and we all might be in for a treat.

Actually, that's precisely the point of the article. Exactly who is this camera for (and, indeed, the 1 system generally)? It *looks* like it's supposed to be an enthusiast model, but misses that target. Do you have any better idea who it's for?

Panasonic has told me that the comment about this lens being F2.8 was simply a mistake.

I've asked Panasonic for clarification, but the size looks much more in keeping with a variable aperture slow zoom (~F4.5-5.6).

So far 35-100mm is all we've got. And Micro Four Thirds mount, of course.

We'll try to make that comparison when we get our hands on the new Sigma, but it seems that won't happen for a month or two.

In reply to:

Stephen Scharf: Andy,
If the locking ISO dial is an issue for you, you can get an ISO Unlocker for the X-T1:

https://www.trycelery.com/shop/isounlocker

Well, technically you can't yet; that's a Kickstarter project that hasn't reached its funding so far. It's potentially a good idea, although it doesn't appear to move the dial from the left side of of the camera. But in principle it should go part way to fixing that irritation, although the X-T1 still won't be as convenient for changing ISO as the X-Pro1, X-E2, or countless other cameras that access it from a single button press without needing a change of grip.

sh10453: I hope someone will now make an adapter for this camera to use Canon's manual focus FD lenses.
Tons of them out there. It would be well worth making it so the L-line FD can be put to good use. If such an adapter is made, I'd buy this camera without hesitation. I have a huge collection of Canon FD (L) lenses.

Of course Canon won't make adapters for any camera to use FD lenses since they want to sell more EF lenses!

Overall, good job Fuji, but I'm not sure if DPR is biased towards Fuji (for a while now) or if the products are really that good.
I haven't used any of Fuji's recent products (over the past few years), so I can't comment.

It surprises me that some people are almost writing their own evaluation in the comments even though this camera is not on the market yet, and they have never touched it in their hands!

We're not biased towards or against manufacturers. We're completely, unashamedly biased towards good cameras.

In reply to:

Stephen Scharf: I think the reviewer has overblown the process for changing the ISO using the interlocking dial. It''s standard practice for pro bodies to have setting interlocks on them when changing key settings. For example, changing the ISO on the X-T1 will still be way easier than on a Canon 1Dx, where you not only cannot change the ISO with your camera held to your eye, but you have simultaneously press two buttons with fingers of your left hand and rotate a control wheel with your right hand to change ISO while viewing the top info panel. In the decade that I've been shooting with pro Canon bodies, I never once heard a pro complain about the process to change ISO. So, while the reviewer grumbled about it in the review, in practice in the real world, I fully expect it will be a non-issue.

You haven't used an EOS-1D X, have you? Canon abandoned the control scheme you describe years ago - to change ISO you just press the ISO button, which is conveniently placed right next to the shutter button, then rotate the front dial. Quick and easy, even when wearing gloves.

In general, Canon's 1-series cameras dropped the interlock model a couple of generations back, in response to user requests for quicker operation. You can turn the interlocks back on in the menu if you so desire, but by default you press a button for whatever you're changing, then spin a dial. Essentially Canon has recognised we're not shooting film any more.

Rod McD: Thanks for this - I'm still waiting to see an XT1 in the hand in Australia......

I suspect you're making a bit much of the issue of the locking button on the ISO dial. I change ISO when the light intensity changes (eg going form indoors to outside and vice versa) or if I make a lens change to a very different FL (eg to bump up shutter speed for a telephoto). It's just not that hard, and I doubt that it's so important from shot to shot when the camera is actually up to your eye. How long does it take - one second, perhaps two? Anyone who so desperately needs that second to grab a shot should have set their camera to an appropriate ISO far earlier. Anything's better than accidental changes.

And as for the inconvenience of gloves... Show me one camera that excels with gloves on. There aren't any. They're all woeful. It's just part of the digital age that they require dexterity to use all functions. This is hardly a fault unique to this camera.

Quite specifically, the cameras mentioned in the text - the K-3 and OM-D E-M1 - are easier to use with gloves on.

As for the locking ISO dial, the text quite specifically states it might not bother all users. But it certainly annoys me; give me a camera that lets me change ISO really quickly and and I'll change it frequently. After all with digital it's just another variable to exploit, alongside shutter speed and aperture.

km25: It looks OK for a zoom, 10mm is just too wide for me, I use my 14mm F2.8 and 23mm F1.4 primes. Never liked zooms.

This is 1.5x APS-C, rather than 2x Micro Four Thirds, so the 10-24mm compares to 15-36mm on FF.

On Kowa to make three manual focus lenses for Micro Four Thirds news story (138 comments in total)
In reply to:

Francis Carver: Kowa Prominar 8.5mm F2.8 MFT

Focal length: 8.5mm
Max aperture: F2.8 / T3.0
TV distortion: 0.12%
Angle of view: 93.5° x 11.7°
Minimum focus: 0.2m

Something is wrong with the posted specs of this lens. If one of the angles of view is 93.5°, how the heck can the other corresponding angle of view be only a minuscule 11.7°?

I can see it being 71.7 degree, but for the life of me cannot see how a lens can give you angular fields of view of 93.5° x 11.7°.

Quick, someone solve this, pls.

This is now corrected; thanks for bringing it to our attention.

(We actually like to add in small errors occasionally, to give our more-vocal commenters something to talk about.)

km25: Why did they not just use the 35mm f/2.0 from the RX1? The camera's sells are going to crash and burning any ways. Sony drops the ball again. Where is their road map of lens, this would at least show what lens are forth coming. Something tells me they have little or no idea. They are depending on a third party for their lens, an excellent lens maker that is not noted for putting out new lens with any speed.

The RX1's lens has a huge rear element placed very close to the sensor, which means the design simply can't be translated into an interchangeable E-mount lens.

Just another Canon shooter: Corner and edge performance is poor even on this high resolution sensor with no AA filter. 1+ vignetting at f/22? There seems to be a price to be paid for the short flange distance.

@Just another Canon shooter: " Also, much of what DXO measures is aliasing, not resolution, anyway." Congratulations, you've just ruled yourself out from commenting on our lens data. As it happens, the contribution of aliasing towards the MTF50 date we're presenting here that's derived from a slanted-edge test is generally very low. It's only ever remotely significant with exceptionally sharp lenses - which is mutually contradictory with your assertion that this Sony lens is poor.

In reply to:

dynaxx: Why wouldn't a metal barrelled Zeiss lens cost more than the two plastic 35mm Canikon lenses mentioned in this Lab Test Review ? Compare the three lenses when they have been used for five years ( and their re-sale values ) and you'll see where the value lies.

The slower f/2.8 is inevitable is you want to keep the weight down to 120 grams and still have a durable construction.

@Plastek - I'm just pointing abortabort to the comparison he requested. I don't understand why you'd be so upset about this.

However, the Canon 40mm F2.8 pancake is unusually good for a small lens, and obviously makes for the most-compact available option on the EOS 6D. The price of the 6D and 40mm F2.8 isn't radically different from the A7 with the 35mm F2.8, either. So if you were thinking of buying a smallish full frame camera with a prime in the 35-40mm range, it makes perfect sense to consider how the Canon 40mm compares to the Sony 35mm. Obviously the A7 is a lot smaller than any SLR, but that's only ever part of the equation.

[EDIT] I do agree that it makes less sense to use adapted EF lenses on the A7.

@Plastek: The Canon 35/1.4L is a relatively old design, from December 1998 - compare it the slightly closer-to-contemporary [EF 35mm F2](http://www.dpreview.com/reviews/lens-compare-fullscreen?compare=true&lensId=canon_35_1p4&cameraId=canon_eos5dmkii&version=0&fl=35&av=2&view=mtf-ca&lensId2=canon_35_2p0&cameraId2=canon_eos5dmkii&version2=0&fl2=35&av2=2) and it performs better at all apertures. Meanwhile, compare the recent [Canon 35/2 IS to its near-contemporary Sigma 35mm F1.4](http://www.dpreview.com/reviews/lens-compare-fullscreen?compare=true&lensId=sigma_35_1p4&cameraId=canon_eos5dmkii&version=0&fl=35&av=2&view=mtf-ca&lensId2=canon_35_2_is&cameraId2=canon_eos5dmkii&version2=0&fl2=35&av2=2), and the Sigma does better at all apertures. But this doesn't prove that faster lenses are 'better' than slower ones - just that comparisons can go either way, depending on how you choose to make them.

Plastek: What about rainbow-coloring across entire frame?

http://www.dpreview.com/forums/thread/3588565

^ IMHO a lens that got a varied color shift on a whole frame is unacceptable, regardless how sharp it is.

We'd cover this sort of thing in a full review, but this is just a brief presentation of formal chart testing results.
