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 (289 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 (705 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

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.

MikeF4Black: 700 grs for a 1.8 85...

To put it into perceptive, the canon 85/1.8 USM is 425g, and nobody complained about its build quality, adding to that it's by no means a bad performer.

85mm is not a typical walk around lens....true. This make things even worse lol....if I were to bring a secondary lens, I'd think twice before taking a 700g lens that I may or may not use.

qwertyasdf: And I thought the previous Tamron 90mm f2.8 macro VC was very good already...I doubt the need for an update...

As a very experienced macro shooter, I'd much rather see something like a 150mm f4 Macro IS lens, that is light. I shoot 99% of my macro pictures at f8 or above anyways. (I think all serious macro shooters do too)

But anyways, such a lens would be too niche....

Yea....hope it's just a cosmetic makeover, really don't want Tamron to waste R&D resources.

Daft Punk: Come on Tamron - Pentax K fit please.

I want to get a K1. So hurry up, make some K fit primes and take my money.

They would probably add a Pentax label together with a nice price premium.

In reply to:

bakhtyar kurdi: What is wrong with their (now old) Tamron 90 2.8 VC?
it is still the king of Macro lenses at 90-105 range, smallest and lightest and most affordable.
The only thing I think of is for some reason it is not selling very well, marketing problem, probably people mix it with older versions.

I don't think a macro lens would ever be a hot seller....
Tamron's 60mm f2 macro was also very good, and could replace a 50mm f1.8....it was potentially a good seller, but I think the marketing flopped for that lens though.
