On article Report: Apple won't release the next Mac Pro until 2019 (210 comments in total)

My 2013 Apple trashcan is still going strong with 16 eSATA cables attached to it via Fitmtek adapters. So far the trashcan hasn't given me any problems. Provided it keeps on working flawlessly - certainly my hope and expectation, it will still be a powerful storage solution for me once a new Mac Pro with more powerful processors shows up in 2019.

ProfHankD: Well, I guess now I can stop trying to build this sort of adapter.... :-(

Congrats to Techart! Leica M mount has a 27.80mm flange distance, so nearly all old SLR (and even many rangefinder) lenses should be able to be adapted to this and anything that uses unit focusing should deliver native IQ. Lenses with floating elements or internal focus generally will not produce as good IQ, but I assume that, like longer telephotos, they'll really just use the AF to tune the manual focus within the 4.5mm flange motion that the AF can drive... so even they will probably be ok in many cases because the focus range isn't that large.

They also say it can drive lenses up to 700g -- and that means it should be able to drive ANY lens when held by the lens, because the A7SII is the heaviest of the Sony E bodies and it only weighs 627g, so it would really just be moving the body back and forth.

I guess now I need to start designing 3D-printable adapters for everything to M mount.... ;-)

Camera plus adapter about 750 g, so about 50 g too heavy for the adapter to move itself and camera, no?

Glen Barrington: Now comes the great guessing game! What OTHER companies will get to use this technology?

I'm willing to go first, though I make no guarantees as to accuracy! Would Nikon or Pentax get this tech? I don't think so.

My reasoning is that Sony seems oddly serious about the camera business this time around. Quite unlike some other product lines they have dabbled in over the years.

Nikon and Pentax seem to occupy the same 'ecological niche' that Sony desires to thrive in. It would seem crazy to help put them on the same level Sony has achieved.

I think it will be Olympus that gets the tech, Sony has pretty much abandoned their crop camera line and m43s has proven surprisingly resilient.

It would make sense to see Olympus as no threat to Sony since they occupy a different ecological niche. Sony could profit off of any Olympus sales while spending no R&D for developing crop camera lines.

Thanks. I hope you are correct with regards to Olympus as I use Sony and Olympus gear most. They nicely complement each other.

On article First Impressions: Metabones Speed Booster (351 comments in total)

I am very happy with the Leica R version of the Speed Booster and am looking forward to the Nikon version. As I am used to manual focus lenses poor AF is a non-issue for me.

Vignetting is more severe for my very long Telyts. However for short tele and normal lenses the slight corner degradation of image quality doesn't really bother me for real world pictures. Of course one can easily see the degradation when pixel peeking.

It would be interesting to have as part of this review a look at wide angle lenses, such as 14 to 28 mm. I only have Nikon WA lenses and have to wait for the fitting Speed Booster version.

I prefer to process some images in ACR of CS6, Nikon's Capture NX 2 or Capture One. How would LR4 fit into this scenario as an organizing principle?

BradJudy: I haven't seen it mentioned much, but this technology can also be used to generate an image with essentially infinite depth of field, rather than choosing a particular focus point and using a conventional depth of field. That's how it's used in industry (and why it was developed in the first place) to create very large depth of field without super small apertures (and thus long exposures).

That's right. My understanding is one needs the full version of the software on a personal computer for this.
