2eyesee: Another APS-C body, but Sony have abandoned APS-C E-mount lens development, and announcing this camera on the same day as three FE lenses is really rubbing our noses in it.

I don't care how good the AF is if after all these years Sony still can't offer a decent kit lens. I got the A6000 when it first came out and returned it because the 16-50 kit lens was so bad. The 18-55 is no better.

Joke is, they still have a better lens lineup than canikon mirrorless

_sem_: I expected a bigger display...

You can, but that's not very convenient is it? Pity camerphones have much better screens, hehe. The flash radio transmitter is tiny but I also find it very odd that a pro camera this size and $$$$ doesn't have one inside...

Jim F: Last bullet point in the description of the D750 firmware update list - "Optimal vibration reduction is now available with vibration reduction lenses." I wonder just what that really means. Does that mean that there is or was a "sub-optimal" option? Curious

@iainlea point 2: Did you use MLU and exposure delay? It is well known that the mirror vibration issue actually gets worse if the camera is rigidly mounted. As for shutter vibration, that's tougher because only electronic shutter or EFCS can work around.

"Unfortunately, Nikon systems show parasitic interactions between mirror/shutter and VR that mirrorless systems don't."

I do recall "shutter shock" issues in the m43 forum, which were attributed to interactions with VR (even when the latter was turned off). Some addressed in FW updates, some in later camera models.

What is the scan time of the fully electronic rolling shutter?
The "noise penalty" means readout with a reduced bitdepth?

lacikuss: My Sigma 15mm Fisheye lens focuses as close as 5 cm from the front element, and is f/2.8

My Nikkor 10.5 does 3cm in front of the lens. But it is nowhere near 1:1 magnification there. Certain Canon wideangles do get around 1:1 on extension tubes, so they could be sold as macro lenses with a different housing with a longer helicoid. But I guess the max magnification is set to maintain certain image quality standards or housing production issues.

If you don't know, better shoot snails ;)

Hugo808: Cometh the hour cometh the lens.

I was thinking the ohter day that I won't get rid of my Lumix compact because the wide angle macro feature gets such good results and SLRs don't have anything similar!

Btw, anybody knows a wideangle lens that reaches more than 1:1 on extension tubes, at a workable working distance? I hear certain Canon WA primes get there...

In reply to:

teddoman: Environmental macro?

You could call it this way because of the low relative blur (mind DoF is about the same as with other macro lenses at the same magnification). Mind you can get similar results with many compact cameras in their macro modes... maybe not so wide but one could use a front wide-converter.

Direct link | Posted on Jun 23, 2015 at 21:31 UTC

Admin, 12 cm must be the MFD, not the working distance from the front element. The latter is probably hardly positive ;)

Well, you can put many wide-angle primes on a relatively thin extension tube. Most don't reach 1:1, but also not all compacts get comparable frame sizes.

CaMeRa QuEsT: Does "Anti-Distortion Shutter"=global shutter? Sony is so adept at giving funny names to common features.

I guess not ;) No word of ultrafast flash sync.

Scottelly: 960 fps at 1080p? That alone makes this camera worth buying. The 4K capability and weather sealing are the bonuses. I think I'm going to get one of these beasts.

The problems with the RX10 II are . . .

No GPS
It can't shoot as fast as Nikon's old 1" sensor cameras.
The screen only tilts, but does not twist/articulate.
It takes an FW50 battery instead of the bigger FM500H battery.
The lens is not interchangeable.

How can it do 1/32,000 second shutter speed?!?

"Stacked sensor allow for faster readout, so they are doing it with electronic shutter"
But this is not yet a global electronic shutter? What is its scan time in full res mode (flash sync speed)?

Direct link | Posted on Jun 15, 2015 at 12:21 UTC

Does it have a mechanical shutter? Sync speed?
Does it have a silent shooting mode with electronic shutter? What is its scan time?

The idea appears interesting. I'm often using a cheapo soft neoprene camera pouch, and a small case for two lenses. I hate this pouch for not offering any rain protection and for an ugly yellow stripe (any chance of getting this one without the light blue camouflage?), while bump protection is an obvious compromise involving acceptable neoprene thickness. But the upsides are that the pouched camera doesn't look much bigger and that the thing doesn't take much space and weight when removed and collapsed in the backpack. I guess this case must look quite a bit bigger with the camera inside and take more space in the backpack when removed?
It'd be nice to see a size comparison with a few other cases when packing the same camera&lens... I mean, I liked some Crumpler designs but I never bought any because they were relatively huge for the same interior space, compared to Kata bags for instance, because of the thick padding.

walkaround: Thank you for finally mentioning D7100 noise and banding, two years later... but better late than never.

"properly ETTRs"... How do you intend to do this? Shoot, download, RawDigger, adjust EC? One issue with ETTR is that the right edge is sometimes not well defined (small specular highlights).

I'm not sure if calling this a test for raw dynamic range is sound. Technically, the DxO and others' DR figures for the D7100 look quite okay. The pattern-noise thing doesn't seem to screw them up much, eventhough it looks disturbing when lifting the shadows. One can get a better result using debanding software (Denoise, Dfine), though unfortunately this is not available in LR and such yet... and I haven't seen a proper evaluation of efficiency of this so far.
