FS7: Canon EF Lenses via Metabones ULTRA - winning FS7 lens solution at the moment?

Hi All.

Apologies for the hyperbole in the thread title, but I wanted to sense check with you what seems to be one of the most compelling reasons for some of us Canon-body users to move over to FS7.

I've just ordered an FS7 (big thanks to Sam Morgan Moore for his help off-line), to replace a Canon C100 with Ninja Blade as my main workhorse - principally for ergonomic reasons plus having broadcast codecs. I need something more compact than my VCT14 rig with the Blade hanging off the side. Also, my near-vision is getting worse and I need a diopter (old fart.)

I've also ordered a Metabones Speedbooster Ultra - I'm not sure if the new Ultra model will resolve any of the issues I've seen in other threads. Do these issues of slow iris response/flashing-open all relate just to the older (last year's) model?

Anyway, the killer feature seems to be the speedbooster/crop reduction properties - sure, I know it's not a new concept, but it seems to not be very prominent on the radar of many EF lens owners. Anyway, it wasn't for me - but I may just need to get out more.

On paper, it seems a collection of L Series EF lenses - combined with the speedbooster - is quite a special brew with the FS7. IS works (essential to me for handheld work - especially with a lighter camera) and my collection of L lenses suddenly increases in "value" by several thousands of £ - ie, to get the resulting FOV and lens transfer speed would cost me thousands more, if I could even find lenses of those spec (cine zooms notwithstanding.)

But... in reality, what are the gotchas that I need to prepare for? By extension, why is anyone buying Sony glass and not just going for Canon/Nikon glass with a speedbooster?

I'll probably look back in months to come and laugh in hindsight at my naivety, but at the moment I can't see why anyone would buy Sony zoom lenses - especially when their kit lens is not adequately wide enough.

Someone put me right on this...

The new Ultra is the worst offender for poor iris control on the FS7, its saving grace is the picture the combo produces, which is stella. Ultimately, it's up to each individual to see if they can put up with its funky operation.

As for Sony glass, there's just not enough options for me. One or two decent lenses does not a set make...
 
If you use the Ultra adapter in advanced mode it works great. There are many positive things using the Ultra and a few negatives but overall I like it and I'll keep on using it.

Positive:
Protects the sensor
About the same field of view as full frame
A stop faster

Negative:
All distortions from EF lenses is shown for better or worse
You have to use the Ultra in advanced mode and sometimes a reboot of the camera is necessary when changing lenses.
