How does the "super macro" mode work?!
Nonetheless, me think this is actually a huge step. Manufacturers had long only provided 1x macro lens, (except the MP-E n Laowa), i always questioned, why stop there?!

I hope we will see native 1.5x or 2x macro lenses in the future.

qwertyasdf: Bash Canon all you want, but they are the only manufacturer that can make lightweight lenses with the highest optical quality.

Of all the EF-M lenses, all are desirable, that's why the original EOS-M is my most used body, it's always besides me in my waist bag. For the times I need shallow DOF or better DR, I take out the 6D from my camera bag. For times I need to use legacy lenses, I reluctantly take out the A7r (I hate it).

Yes, I hv owned the 40mm XS, truly amazing. But then they are not as light or as cheap as the Canons, nor does Pentax have a small mirrorless (the Q is dead).
Olympus was also exceptional at making small and high quality glass, but only in the film era.

Donald B: what is the point of a 28mm macro lens, the designer obviously has never shot macro before.

I think it's a conscious decision, since for the LED to be effective, it has to be very close to the subject, a longer lens would render the LED useless.

It won't work for bugs, but for static subjects, the focal length is not a major concern.

jnd: For static scenes the pixel shift is great. People say also for landscapes but with that amount of detail what about moving leaves, waves and reflections in water and such? How fast does it capture during pixel shift?

ISO 6400 in pixel shift mode looks so smooth compared to standard shutter, it's like magic, great improvement.

It would need more than 4x the exposure time, especially during very fast shutter speeds. The E-shutter may take more time than the actual shutter speed. (Okay, can someone help me explain the technical details :P )

qwertyasdf: I think ISO / noise performance advantage of pixel shift is merely theoretical. I can't think of a case which the stillness of the scene could afford you to use pixel-shift, but at the same time, you need high ISO.

@samhain
If you can use pixel-shift, it means that the subject and camera are both stationary, there's also no need to use high ISO in the first place.

Puljak: Dpreview, what was the purpose of making this test public once you realised that the lens was subpar? Your comment about the lens is now buried deep inside this comments section, and people are left to judge the results of a new camera on the basis of inconclusive data.

You could have at least left a comment at the top of the page that the test will be revisited once you receive a good copy of the lens.

Yes, DPR is not doing the K-1 justice!

On article 2016 Roundup: Compact Enthusiast Zoom Cameras (290 comments in total)

Whenever friends or relatives consult me on which mirrorless camera to buy, I usually reject their idea, and offer them my rule of thumb:

If you plan to buy less than 3 lenses, stick with a high quality compact camera, they are freaking good nowadays.

qwertyasdf: Wow, I'm totally impressed, they listened to their customers (complaints), and solved the poor LCD problem of the M9!!!

They can proudly proclaim: The problem is now gone!!!

On article The Canon that can: Canon EOS 80D Review (711 comments in total)

Reviews nowadays have a strong focus on DR, but this leaves me wondering, if this metric is so important, the Fujifilm EXR cameras of the bygone era should have been much much more popular that it was!

Toselli: "...offers stabilization, 1:1 magnification and focusing as close as 13.9cm/5.5in"
Isn't the normal distance for 1:1 magnification of lenses around 100mm of about 30 cm? Does this lens reduce the effective focal length when focusing close or is it calculated from the front of the lens instead of the focus plane?

I think 13.9cm/5.5in is the minimum WORKING distance, which is different from the minimum focus distance, which manufacturers list by convention.
MFD is distance from subject to focal plane (the sensor), MWD is distance from subject to the front element, which arguably is the more useful and convenient figure.

AlliHjelm: (Sorry, my other post did not post correctly. Here it goes again) :)

Nice review and well balanced. Agree with most of the cons, which are all of them fixable with a new firmward.

My humble Leica Q review:

Yes, the Q is an amazing pice of machinery. Bravo Leica!

After reading your review, I honestly think that the photographer is what matters most :) Awesome photos!

Best thing I like is that they offer two versions, a tough version and a lightweight version!

Hope other manufacturers can do the same, because there are many people (like me) whom just take good care of their lenses, not even a scratch after years of use. I'd rather sacrifice sturdiness to bring a few extra lenses!

Need to consult an equivalency troll....cough...cough...um...i mean expert on how these cut up lenses work.

Ilia Snopchenko: "It's got 32 elements in 18 groups." (slide 7)
Looks like someone was a little bit too excited while typing. :) Looks more like 23 to me (which is the same as the similar Canon lens).

Though I wonder what lens could have 32 elements - I think 23-24 is as much as we're getting in consumer products now. :)

I can only count 22 elements in 17 groups lolll

qwertyasdf: The sensor size between the APSC and APSH body is very small!
23.5×15.5mm vs 26.6×17.9mm

The sensor size of Canon 1D is 27.9 x 18.6. So the Quattro H would probably give a crop factor larger than 1.3x

Interested to see if this is deliberate, if it might be that a lot of APSC lenses have an image circle around the size of the sensor inside the Quattro H.

By larger...1.4 is larger than 1.3....and so on

The spec does list it as 1.3x, but precisely, it's 1.349x....so marginally correct to be rounded to 1.3x lollll
The APSC model's crop factor is 1.536x, so the difference is only 0.187x

In reply to:

Nick Spiker: It's too bad really, you've taken a SLR flange distance, but not given us the benefit of a mirror. So now we have to use the screen and have to use Sigma lenses. It's a sub frame camera, with a full frame size mount, so now we've wasted the extra area with a crop factor.
Good job :(
Don't get me wrong, I love the Foveon design, I even have a SD-14, but can we please get a full frame with a short flange distance?

"The further flange distance however makes it easier to create lenses"

This is totally untrue, for shorter flange distances, a lens manufacture can always add in extra distance by extending the lens tube. But it can't be done the other way.
