On Otus Readings: the Zeiss 85 F1.4 Otus Comparison article (217 comments in total)

For the remark obaout Olympus 45 1.8 resolution,
as it's sensor shift, and always a 16Mpx sensor, I don't understand why the lense should limit more the total resolution ?

For the sample I saw, it was more that pixel shift was not equal to a real full res sensor .

electrophoto: If only they would have added a 35mm lens ;)
Well I'm glad they didn't - otherwise I'd find myself tempted.
Never been a big fan of 28mm in a fixed lens camera....
I've used some - and always found my X100 23mm (=35mm) lens far more useful on a fixed.

nice camera so... especially throwing in some modern...
I'm not much a leica shooter (used to shoot some film Leicas years ago, but the price tag never was my range... ) but I can see why the Q is an interesting product.

If you do a crop, you are at the same working disatnce, you only keep what is the angle of view of a 35mm at the same distance
-> so same perspective.
But If you want to have FF the same framing than the 35mm, you have to reduce this working distance with your 28mm, and that change perspective
;)

Artak Hambarian: ...and also please at least a modest zoom like 20 - 40 mm f/2.8. In that case I would pay even $6k. This would help me not to change my lenses on the dslr so frequently. If you like this idea, give me a discount, Leica!

what is AF performance in low light ?
I expect -3ev with this sensitive sensor,that would be great

-4 is A7s territory

In reply to:

forpetessake: When will DPR stop publishing misleading numbers? It's NOT "a mind-blowing F2.8-6.5 24-2000mm equivalent zoom".

You either provide conversion for both f-stop and focal length, which are mind-blowing F14.6-33.8 24-2000mm FF equivalent. Or provide the physical parameters, which are F2.8-6.5 4.6-385mm.

It's hard to believe DPR continues making honest mistakes -- writing a F14.6-33.8 4.6-385mm would have been an honest mistake, and I've never seen that.

@mosc, not totally exact:
Use a FF200mm f2.8 on FF or APSC, full open you always use the 71mm aperture, and it's what give the light on the sensor or film by area unit, so You can use the same result of an external lightmeter to setup both cameras.
But as you say, the APSC sensor is 43¨of the FF sensor, so the total of light light/area*area is 43% less. That's why you for a similar picture, you have around 1stop more noise. Then for DOF, with the same physical aperture, as the angle of view is shorter, you have to go back 1.5x the distance to get the same shot, and so the DOF is 1.5x the one of a FF body, because you don't shoot the same picture at the same distance. If uou shoot at the same disatnce, you have exactly the same DOF if you shootyour 200mm at 2.8, but you have not the same picture.

"By forpetessake (4 hours ago)
Please refrain from the silly f2.8 is f2.8 comments. It's good to know the subject before commenting and embarrassing onesel"
perhaps you don't know the difference between physical f2.8, and the quantity of light the sensor gets per area unit or in totality ?
Sorry 2.8 is 2.8. Then you can speak of equivalent for focal, DOF or overall quantity of light the sensor gets.

En Trance: Finally, a manufacturer correcting shortcomings for free. Wish there were more out there.
Too bad, I do not like Nikon. Don't know why?

@ En Trance
I love Nikon, I dislike Sony, but I love the A7 line, size and look, and I sold my Nikon gear, bought A7 and A7II and try to live with all their shortcomings...
As you say, many persons and many roads

Stigg: hmm, no matter the weather you just keep taking boring snapshots. even antsy bad-breath adams could make more interesting mediocre shots than these. try throwing your camera at some rocks or off a cliff. they'll definitely be more lively than your usual.

hmmm, boring unintersting comment, threw your keyboard against the wall, it will definitely be better than your usual.

That's why no D400 :) :)

Cane: Why does Sony let Zeis make almost all their FE lenses. It's like Ford having Ferrari make all their engines. Just because a camera is FF doesn't mean only $1000 + lenses are the only thing you should attach to it.

Maybe this is such a great plan that Canon should follow and only sell L lenses.

The 35 1.4 was annouced before,
but you're right I didn't see they put it in the list
;)

le_alain: Thanks !
as startup time with an FE lense on A7 is 3x the start-up time with a legacy lense
On A7II the startup time is better , around half the A7

No, on A7 series, before update, it makes near 3s to boot with an FE lense. Try it with a chrono ;)
on A7 II it's far quicker
