  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

14-20 Tokina 2.0 announcement.

That's great news !!
As mentionned in the linked post, pair that 14-20 f2 with the terrific sigma 18-35 f1.8 and you've got a killer combo on Raven ;)
 
Super curious if this lens will work on FF35 above 16mm similar to the Tokina 11-16 and 11-20.

(I'm considering selling my Canon 16-35mm 2.8L II to buy this and the Sigma for that extra stop+ they offer, but need to be able to hit 20mm on my SLR for stills)
 
I'm still hoping Sigma (or Tokina) comes along with a super-speed prime set for APS-C... As in, f1.2 across the set (18 to 85) and affordable by stills lens standards. I mean, they've already got an f1.4 set for FF35, so I was hoping they could pull f1.2 off with an s35-sized image circle...

As for zooms, 24-70 f2 please! Better yet, something like 35-90 f1.8 ART would be insanely welcomed!

Does APS-C lenses work on Raven?

Can't tell if you're joking or not? Raven is currently EF mount only.

I think he's inquiring if the glass will cover the sensor. If so, then yes. APS-C will cover both Raven and Scarlet-W.
 
Hi Mike. Yes I am aware of Raven is EF Mount only. What I do not understand is this Tokina 14-20 is Canon and Nikon Mount but for APS-C sensors. So would that be EF mount or EF-S Mount. Will it work on Raven with a sensor that is not APS-C size? (Never used anything else than fullframe cameras) thanks
 
Jonathan,

APS-C is around x1.5 (Nikon) to x1.6 (Canon) in terms of FF crop, while Raven is around x1.8, depending on what aspect ratio you set it to. Scarlet-W is around x1.5. As such the lenses should cover.

As for EF-S, don't quote me on this, but as far as I know only Canon makes EF-S lenses, so any other brand is just a plain EF mount (regardless if it's APS-C or not). Some EF-S lenses can easily be modified to still fit cameras that don't support them (the 24mm pancake lens for instance). No idea if Raven will or not.
 
Yes to all that.

EF and EF-S lenses use the same EF mount (the "-S" designation is merely to signify lenses that only cover APS-C). And for motion film, super35 is actually very close to APS-C while VistaVision/65mm motion film is close (but-bigger) to FF35.

Bare in mind that regardless of sensor size, Focal Length stays the same, while FOV changes... So while you may normally use a 24mm to get a super-wide on Full-Frame, that FOV is actually closer to a ~14mm on S35/APS-C (though depth of field would be much deeper on the 15mm/APS-C compared to 24mm/FF35 combo). Raven is close (slightly smaller) to super35/APS-C size.

Respectfully, this is actually incorrect. EF-S signifies that the rear element of the lens actually protrudes further. As such, it can cause damage when used on non EF-S compatible EF mounts (the rear protrusion physically hits the sensor).

As far as I know, only Canon makes EF-S lenses with this issue (the 17-55 being an example), all of which are APS-C. All third party APS-C lenses use the standard EF rear element spec.
 
It would hit the mirror before it got close to the sensor and it uses the same physical mount... Being that Raven/REDs don't have mirrors, they've got plenty of room behind the mount.

Not saying this isn't true, but what EF cameras bodies actually have trouble fitting EF-S lenses (including the 17-55)? Also, are you saying EF-S lenses cover FF35 sensors?

edit: found something that said the design spec allows for a rear element for shorter back focus that could theoretically hit the mirror of FF cameras, but in practice a.) none of them actually do and b.) they only have an APSC sized image circle, so logically no one would ever use an EF-s lens on an FF camera...

So yeah, the physical mount/connection is the same. The image circle is different.

Mike, the mirror vs sensor that you mentioned makes perfect sense.

Heres a link to the EF-S wiki that addresses the issue. I suspect that you're correct in that it won't be an issue on Raven since it has no mirror. I know that it's extremely problematic with speedboosters and such, but again, that doesn't apply to Raven.

Good call.

Since the Veydra lenses with the Sony E mount cover S35 size sensors I really wish theyd release a set with Canon mount for Scarlet-W & Raven, theyd be a great match...

Most likely they would have already if they could since that is a bigger market and most people would likely buy in canon mount to adapt to other mounts. The lens design appears to be dependent on a short ffd and they'd probably have to completely redesign the lenses if they had to move all the rear components/elements/mount more than twice the distance from the sensor.

Yeah, totally agree now that I think about it. Just wish it could be, haha.
