Sony PXW-FS7 things you should know…”Adapters”

Categories: Miscellaneous 6 Comments

Adapters

For those of us contemplating the arrival of the Sony PXW-FS7 here are a few tips when it comes to adapters…Some of you may be contemplating buying adapters for the FS7 but beware…read the small print first.

FF-v-S35mm-v3

Firstly I was reminded that the FS& is not full frame and is in fact Super 35mm so the Metabones Speedboster will indeed be fine.

Speed-booster

Metabones EF to NEX Speed Booster ULTRA

  1. This Speed Booster ULTRA is designed to cover an APS-C (23.6 x 15.7) image circle which is not big enough to cover a full-size 36mm x 24mm sensor. (Remember the FS7 is 23.6 x 13.3)
  2. Dan Chung “Also beware the EF Speedbooster Ultra can be buggy with FS7 – sometimes not recognised”.

NEX-Smart

Metabones Canon EF Lens to Sony NEX Smart Adapter (Mark IV)

1. A7S (Mark IV supports auto “APS-C Size Capture” with EF-S lens)

Sony-Ad-1

Just when you think you can upgrade to the Sony “A” lens system you read the small print to learn this adapter won’t allow any lens to open any greater than f3.5 making those f2.8 “A” lenses redundant ?

1. Aperture setting for video capture is fixed at the maximum aperture of the lens or F3.5, whichever is lower (AF-C).

Sony-Ad-2

Strangely enough the Sony adapter at £159 almost half the price of the one above seems to have no such restrictions.

From what I gather the FS7s are due to arrive at the end of October in limited quantities…watch this space.

    The LA-EA4 has a phase detect AF system integrated into it (hence extra cost). It’s really designed to give snappy AF speed for stills rather than for video.
    The LA-EA3 is a “simple” adapter.

    The LA-EA4 also supports AF on screw-driven A-mount lenses, the LA-EA3 doesn’t.

  2. Hello HDWarrior,
    I’m not sure to understand the first remark,
    The FS7 is a Super35mm so it’s not 24×36 but about 18×24
    The metabones adapter should work as it will cover it, no?

    The fs7 has a super 35mm sensor (~25x19mm) so the speedbooster should be fine shouldn’t it? I think my camera is due Fri/Mon along with the metabones SB

    I think a few of us are getting a little confused with this post. Not complaining, just requesting a little clarity.

    My Sales guys suggested the Ultra with the Canon 2.8 L zooms I have but I’m hearing there are issues. Can you just suggest which one should work properly or don’t any at the moment? I’m assuming all my Samyang T glass will be ok anyway as they are mechanical anyway?

    Cheers & thanks for all the good work

    HDW : Hi Andy, by posting this I have already had Dan Chung’s input on the Metabone adapter, there are very few FS7’s out there so we are learning all the time, what works and what does not.

    “Just when you think you can upgrade to the Sony “A” lens system you read the small print to learn this adapter won’t allow any lens to open any greater than f3.5”

    There is confusion here. If you want AF during video with A mount lenses (PDAF AF as those are DSLR lenses), you can’t change the aperture. It’s always F3.5

    However, if you are on manual focus mode, you can set the aperture to anything. F1.4 to whatever, F22

    Thanks for the review it´s very helpfull,

    I just get the new FS7. Will you please help me with the right metabones, I have canon lens as 24-70 2.8 and 70-200 2.8. I had read that the speed booster ultra is not going to work properly, so I´m not sure if I should get the previous speed booster or the Mark III. I am very confuse about it and I will really appreciate if you can help me with this matter. Thank you very much in advance. Sergio

    HDW : Sergio, I don’t own a Metabones adapter so I can’t help you but maybe one of our readers can.
