I did some tests with the intelligent digital zoom on the a7s and I'm pretty convinced it's some kind of sensor crop. My theory is that the processor is cropping into the 4k video to get the zoom as opposed to cropping into the 1080p video. So the video quality is actually really good.

 

Here's a video showing some tests I did with it. 

it would be quite easy for the big players to shut this down.

at the very least for months.
the big guys patent everything and store the designs even if it was for a different system.
not saying anything will happen my hunch is that the first model will have a few glitches but within short time it will be near perfect.
the majors will want to protect themselves.
nda the designer and buy the company i would say pay off everyone.
the cia haver been doing that for years and they are a trillion dollar industry.

jp morgan and the fbi made most of tesla's ideas vanish into the military industrial complex and we are still stuck with oil.

this is a small beer payoff issue the big players may treat it like or may get a little proactive.
but this has serious money implications for the big sensor boyz

 

I don't think I'm quite as cynical as you, but just in case that's also why I bought my adapter as soon as  ;)

I'm jealous! :) Love to see footage! What camera and lenses are you working with?

 

Sony NEX 5N and mostly Nikon AIS lenses and some old Russian lenses. Should be a good test to see if they really improve image quality because old Ruskies get mad soap opera wide open. I'll post footy soon.

 

What about if there was an Alpa to FD adapter and Alpa to EOS version etc. Do you think they would work? It would save buying lots of speed boosters.

 

I looked it up and nobody makes Alpa to anything adapters that I could find. It's such a bizarre choice. I was thinking the same thing too because I really don't need a smart adapter.

Here is a link to calibrating for infinity

Any chance you could try adapters on the front of the speed booster, like a nikon/pentax adapter etc? Any one know if using adapters on the front of the speed booster causes any problems? Could you describe how well the autofocus works? Cheers.

 

 

Thanks for the link. I knew there were instruction for it I just forgot where they were. Adapted Lens work well although I can't compare them against how they work with EF lenses because I don't have any EF lenses (if you are wondering why I bought the EF version then, It's because I used to have a T2i and all my lenses are compatible and adapted for EF mount.) A friend of mine has a couple EF lenses so I'll probably try and test them out on the adapter this weekend.

Hi all, I pre-ordered the adapter and just got it in today. I am planning to do a thorough review of it soon, but for now I've just been messing around with it. As far as I can tell, there is no loss in sharpness or light blooming or any of the other weird effects that adapters with built optics often have. I'm not sure if it makes lens necessarily better, but I don't think it makes them any worse. It really is like having a full frame camera.

 

The speed boost really works too. It feels kind of subtle from F1.4 to F2 but it's really obvious at F4 and slower.

 

There is one caveat and it's potentially major and that it doesn't seem to focus quite to infinity. It's almost there but it's just a little soft.  I think focusing in general is thrown off a bit as compared to the focus marks on the lens. Like, it might focus a little closer than normal. However, I could be wrong and it might focus to infinity. I haven't done the proper tests to confirm this. 

 

All in all, this looks like the real deal. And it's really not that heavy to address that one dude who was saying something about it being 197 grams or whatever it weighs.

I don't have a Hackintosh or have edited raw but I do have some comments on using Geforce cards in Premiere CS5.5. Definitely get the 6 series over the 5. Even though there isn't a huge performance boost, the 6 series cards allow for 4 monitors per card which is huge for editing. I use a gtx 560 ti and whenever I incorporate large picture files into my videos it crashes. From what I hear it's because it only has 1 gig of ram (although it could be something else.) most of the 6 series cards have 2 gigs and up while the 5 series are almost all around 1-1.5 gigs.

I think this obsession with 4k for the masses is a little premature. There are barely any non pro cameras that can even deliver legit 1080p. I think one of the big obstacles in Nikon's way is the fact their lenses rotate backwards. It may not sound like a huge thing but from what I hear that drives a lot of focus pullers nuts.  They need to make a line of video lens that rotate the other way.

Do you know of any video tests being done with the D800E? Do you think it would have similar image quality to the regular D800? This is somewhat important to me because while I primarily use my cameras for video I'm also a painter and I do need a camera to take the highest resolution pictures of my work for prints and it would be nice to have the extra resolution of the D800E if it does not add a significant amount of moire and aliasing on the video side.
