Re: metabones lens adapter for Canon EF lenses on Sony E-Mount

Seems like a pretty neat idea.

I guess you just end up with the lens behaving the way it would on a full frame sensor.

50mm f/1.4 -> 35mm f/1 = 50mm f/1.4 (FF equiv).

Re: metabones lens adapter for Canon EF lenses on Sony E-Mount

50mm 1.4 = 50mm 1.2 with higher optical quality than original.

Interesting

Very interesting adapter.

It says "‘Speed Booster’ is a 0.71 x focal reducer" so it should be 0.71x1.5=1.065 multiplier...

So 50mm becomes 53.25mm and 100mm becomes 106.5mm on the crop nex cameras.

Sure, I guess, but that's because the adapter allows you to make full use of the optics on a lens designed for FF (instead of a simple crop factor), so I think you're basically just trading increased sensor noise for optical quality.

re: a pretty tricky question - how about vignetting?

lets suppose we will mount the EF 100/2.8L IS through this magic-reducer on N7, Photozone reports for it vignetting of 0.71 on 1.6x crop EOS body - according to Bloom's overview it will be now 70/2L IS lens on E-mount body; but... will vignette be reduced as well to 0.5 or... be boosted to 1.01, or 1.41 or something else entirely??

Re: metabones lens adapter for Canon EF lenses on Sony E-Mount

Like a teleconverter this might work well with some lenses and not with others.

As stated it basically makes the lens have the same aperture and field of view as it would on full frame.  I.e. a 35mm f/1.4 used on APS-C is equivalent to a 50mm f/2.1 on full frame.  What this adapter will do is make it so a 50mm f/2 lens used on full frame would be the same as the 50mm f/2 lens used on APS-C with this special adapter. So you are getting your full frame equivalent lens.

My guess is it will give some where and that is probably in image quality in some regard.  You are adding optics to the lens that it wasn't designed to have there.  I have seen people discuss these adapters before, maybe they wouldn't work as well on a longer flange camera though, so maybe that is why they haven't been done yet.

If my understanding is correct (from Figure 1 in OP's link), the vignetting w/ the adapter should be comparable to that of the lens on a FF-camera. It doesn't get reduced like it would be if the adapter didn't have any optics at all. In fact, it's possible (likely?) that the additional optics will introduce some additional vignetting.

Re: re: a pretty tricky question - how about vignetting?

EOS HD will  be testing the same adapter also:

Per his comments, "the Speed Booster shrinks the image to fit the sensor" so you will get the same vignetting.

Unbelieveable! MAkes sense in terms of optics.

Looking forward to a more professional review in terms of some technical qualities and proper charts, but this could be a game changer for the NEX format.

Re: metabones lens adapter for Canon EF lenses on Sony E-Mount

This could have huge ramification for the photography world.

Getting a Sony, Panasonic, and Olympus's mirrorless cameras to perform like full-frame DSLRs with EF glass could result a lot more folks switching to mirrorless cameras. You already got cameras like the NEX 7, EM5, GH3, really closing the gap between themselves and full-frame cameras in IQ and features. This adapter could potentially close that gap completely. But the question is: should Sony, Panasonic, and Olympus be happy about this or not?

They would benefit from having a increase in camera body sales but on the other-hand this could potentially kill any sales from their own lens lineups. They could still argue that with the size of EF lens being bigger will result in the camera being front heavy and that their lenses are optimized specifically for their sensors, but EF glass is very popular and a lot folks invested a whole lot of money into them.

If this adapter is found to perform as advertised, it will a interesting year in the war between DSLR vs. Mirrorless.

If I was Canon or Nikon
1

I would be paying this company $200,000,000 and closing them down right now !!

Don't laugh, it might happen yet. That is clever stuff.

With the way this company has progressed with these adaptors, it won't be long before they do the Sony equivalent and PDAF the darn thing to take Canon and Nikkor lenses, some how. Yep, I would buy them out now !!

All the best.

There is another thread going on about this. NOTHING NEW HERE!

Listed are about 4 similar EF/EFS to NEX adapters which permit full AF/aperture control. They run over $130 and should work OK.

Then there are numerous cheap $20 ones that are manual only...not so good for a non-manual lens.

Then there is an intermediate model for about $60 which looks like good quality and incorporates it's own aperture mechanism as part of the design. You still need to MF.  Like!

I just posted that in the other thread a couple of hours ago. Too lazy to re-post now.

Re: metabones lens adapter for Canon EF lenses on Sony E-Mount

Just remember that nex does not have a FF sensor, so it won't be the same as a FF DSLR.

on the other hand, making full use of the glass and allowing all the light on the sensor

sounds good!  There is more glass, but it will be interesting to see how it performs.

yes, this is my reasoning too, so for our example lens 100/2.8L IS we should be looking at vignetting data for it on FF body, and PZ gives value of 1.55 which is pretty close to the theoretical 1.41, but... only doing real tests will give a full answer

from purely theoretical standpoint - like downscaling to 16 Mpx is often advocated here for 24 Mpx files from N7 (thus killing the resolution advantage) for comparison purposes with 5N and its 16 Mpx kins

re: some very importaht details are trickling down - one of the foremost...
  • DMF mode (direct manual focus) is not supported;
  • is this acceptable for a 600$ adapter?
  • esp. as the AF is: "very slow and inadequate for most moving subjects. The autofocus speed is unfit for professional use for sure, and it would disappoint most enthusiasts".

I was just reaching for my CC to pay, but luckily spotted that note about the lack of DMF in time !!

Re: re: some very importaht details are trickling down - one of the foremost...

This is a great news for us. I think the idea is borrowed from Contax's adaptor for using medium format lenses on 35mm camera body and the 'condensed' images are brighter and of higher quality, and the price of the adaptor is around few k. Not very sure though, maybe someone who knows can provide more info on this?
