On Yongnuo creates near-clone of Canon EF 35mm f/2 article (160 comments in total)
In reply to:

Juck: Can we assume it performs as well as their 50mm 1.8 clone? i.e. crap.

yea, af is a bit noisy and sharp around f4 and after.

rrccad: okay. so if I'm shooting static scenes. why do I need pixel shifting, since I can usually keep the ISO low, and increase the shutter speed anyways, since you're a) already using tripod (have to for pixel shifting) b) taking images of static scenes.

at least with Olympus - you can see the benefit for product photography, this though outside of reviews .. I'm at a loss to when I'd actually use it and need it.

should be interesting to see all the people in here SCREAMING in mortal agony over the lack of a flash, wifi, articulating screen,etc,etc... especially after all the ranting over the 7DII not having it ;)

zos, i certainly hope so. happy shooting.

In hydraulis, noise from heat didn't turn out to be my major concern with a7ii. u r right, battery was very short, even using only the evf.

guess i will wait.

many good points. no wifi is a bit strange.

in terms of more accurate color, this technique is practical for still product shots and K3m2 color accuracy could be in the territory of Sigma's 3 sensors stacked together. cool.

ricoh could've do the olympus style of sensor shift w/ color accuracy at the same time. Guess they don't want K3m2 eat into their larger frame.

speaking of ricoh, they are doing their branding a disservice. with full frame mirrorless is so hot, now. They could have release a FF mirrorless using their own brand. since pentax is well known in SLR history for it's 35mm SLR and medium format 67 (a SLR on steroids. :)

mirrorless FF gives Ricoh a branding they tried on pentax dslr, which didn't work well. also, ricoh can roll out the super sharp, super small light weight range finder lenses liked those designed by leica, voigtlander, and etc.

take a look at mamiya 7, esp. how small the lense can be, yet so super sharp for the entire image circle/frame.

Reinhard136: " Especially given all the competition- the 6D, D750, a7R, and a7S all outperform it by a good margin". I thought now they have gone too far, worse than a canon ! no way . Have a look, it is true ?!?! Par with the A6000. Either there is a master conspiracy in the studio, or Sony has slipped ....... or are they lying doggo on the sensor because there is something very nice coming, to slap everyone down with ........ ? Will stick with the A 6000 till sony reveals its hand.

Reinhard136, please check out this hi iso comparison between d6 and a7ii, both are full frame. btw, d6 is 2-3 yr old vet, released back around nov 2012.

User3754336485: Heaviest mirrorless ILC camera or lightest full frame camera?

Seems the weight is in the arm of the beholder. I've trucked around my Nikon d7100 plenty and the a7ii is a dream to carry in comparison.

sweet dream. :)

In reply to:

adengappasami: Strange that there is no mention of third party lenses and how the IBIS works. Considering the camera series has basically opened up all old manual lenses and brought them back to life, it would have been better if the review added a session on how the camera handled the manual third party lenses and how useful the IBIS was.

3-axis "could" work fine in many cases, when the shutter button is assigned to the back of the cam. so, the "shake" becomes forward and backward, smaller in image quality loss. vs. clicking shutter from top causing an up and and down (or rotating) "blur".

assigning shutter button to the back has been the trick since the film days...

In reply to:

exapixel: For still photography, I'm not sure whether I understand how IBIS is better than using a faster shutter speed and a sensor with lower noise at high ISO.

exapixel, I find the enjoy when I was handhelding the cam shooting at 1/8 of a sec w/ F2.8 and ISO 3200 and the IBIS on. may the force b w/ u. ;)

In reply to:

jhinkey: "All the size/weight advantages of not having a mirror mechanism are negated the second you try to squeeze an IBIS system inside the body."

Hardly. It's still smaller and lighter than the D750.

Who is the editor of these articles?

A7ii is small and denser than other FF or APS-C cam. It is denser and one will feel it from the moment pulling (or yanking) out from the box.

nice series that show the very little degree of vignette from the lens.

In reply to:

Mike FL: Canon needs to make its AF system works correctly for P&S cameras like G7X, or system cameras like EOS-M.

It is interesting to see a #1 camera mfc do NOT know how to design an AF system for mirror-less.

Other than POOR AF, Canon is also well known for its POOR battery life for mirror-less, G1X-2, G7X, exc.

If I were Canon, I do not like to see "POOR AF + POOR battery life" become well known signature of CANON.

YES?

I am not sure Sony's mirrorless alpha 7II has got a firm grip on AF, either. check out the Gary Fong's preview. In his vid, the 7II tracks/follows subject, but , subject is blur/out of focus.

In reply to:

Anastigmat: If these cameras are aimed at landscape photographers, they should have built-in GPS, because the landscape photographers often take pictures where there are no roads, no buildings and no identifiable features. A GPS reading would allow the photographer to pinpoint the location of the camera from the EXIF data and return to the same places months and years later. Hope that Canon will include a built-in GPS when the time the camera arrives in the market place.

Anastigmat, GPS is too logical. It won't fly. :)

Shiranai: Meanwhile at the Canon headquarters:

Manager 1: We rule the camera market.
Manager 2: We rule the world.
Manager 3: But we don't rule medium format...

Moment of silence, chirping.

Manager 1: Doesn't mind, release a new 5D, squish 50 MP on the sensor, but cripple something so it doesn't compromise 1DX or 5DM3 sales.
Manager 3: Video mode, like we always do?
Manager 1: Good, but thats not enough. Do something with the ISO!
Manager 3: Perfect, we are so naughty.
Manager 2: Oh yeah, and the others did that aliasing filter thingie last year.
Manager 1: Ok I have a great idea, let's release two 5D models one WITH the aliasing filter and one without, that'll teach them a lesson. Also, put a medium format price tag on them so they know we are serious.
Manager 3: But they aren't...
Manager 1: Shut up, and make it so. We are Canon, it's not supposed to make sense. The main point is, we release something new.

Evil laughter while picture zooms outside of the headquarter.

And FBI think N. Korea hacked the footage, because hacker was sloppy.

In reply to:

nicolaiecostel: I hear this again and again and it really bugs me. Pretty please, explain why a wedding photograper need 50 MP ? I shoot weddings since 2008 and I'm perfectly happy printing 25x50 cm album spreads from the 12 Mp D700 or 70x100 cm wall prints. Why on earth would I buy a camera with huuuge file sizes, not that fast, not good in low light and with bad DR, instead of a camera like the D3s/D4?D750/5Dmk3 ?

these new dual are for landscape and architecture photographer who likes slow mo on tripods.

Direct link | Posted on Feb 7, 2015 at 02:04 UTC

would it be full frame mirrorless and take k mount? i would hold on buying the other brand's FF mirrorless.

excellent choice on subject to show case the sensor latitude to retain high light and showing the shadow detail in one shot.

good job!
