  • 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 :)

PL Mount 11-16mm f2.8 Prototype, Manual Iris

For a suggestion, maybe you should make the focus ring wider, to cover the Tokina rubber ring... will probably look more professional?

As noted in the previous post, the Focus Gear is being changed to aluminum and will cover the rubber. No worries.

Great!

After that would be nice to have rehoused Nikon 17-35mm f/2.8 and Tamron 28-105mm f/2.8 and with those three light weight zooms (each zoom is less than 1 kilo) you could cover the range from 11mm to 105mm @ f/2.8 for R1.

Not likely.. The lenses you listed are not stable throughout the zoom range.
Granted, the Tokina isn't perfect... But it's much better than the 17-35 and has a much shorter range.
A lens such as that would require a complete re-house. I'm not saying it won't happen... It's just not on our drawing board at the moment.

Nobody's perfect.

But have a look at those three "non-perfect" still lens (all f2/2.8)options here>>>
 
If we were going to re-house a set of zooms to complete a specific range, it would be...
Nikon
12-24
24-70
70-200

That way you cover 12-200. But like I said, those would require a complete rehouse similar to Stuarts Ruby lens.
Far more in depth and expensive.
We are trying to keep the cost of our conversions low and appeal to every day shooters.

Great!
 
Nice looking poster. Covering the focus ring will indeed make it look a bit more pro. Though I don't care either way, the numbers are there, so are the images. I just wish I had a chance to check it out in person.

Maybe when the time comes I'll pay you guys a visit and as it turns out my sister is moving from Florida to Thousand Oaks... which puts you on the way there, a great excuse to pester you like you wouldn't believe. j/k :thumbsup:

Are those actual T stops? Does T2.8=f2.8 on this lens? Is that possible? Thanks

Did we miss an answer to this question?

I'd love to know the actual T stop, even if it were T3, people are not going to freak out. Or at least know if there will be an actual T scale on the ring. As far as I remember it wasn't directly addressed yet.

I'm waiting to put it on a T-Stop bench and get a concrete reading.
The marks on the lens I brought to NAB (as well as the one in the photo) are for the prototype only. The scale will be marked in T-stops.

You're welcome to stop by.
Thousand Oaks is only about a 20 minute drive (pending traffic) from our shop.

This image shows the lens set at 11mm. I marked where 5K coverage is.
The image just barely covers to 5K and we are looking into cutting back some more of the front housing to see if that's the wide angle coverage limitation.

Any news on this? Thanks!

Tokina did a great job with their coverage and baffles.
It seems that the front element baffle and housing are EXACTLY where the image circle begins to clip. So reducing the front housing will not gain any coverage. Still covers 5k (or whatever RED decides to call it) from 12-16mm just fine
 
Alexander Christ said:
5K on Mysterium-X or Monstro?

I should re-phrase that...
The image circle grows drastically when you zoom to the telephoto end.
At 11mm the image circle is 32mm.
At 12mm the image circle is 34mm.
And so on... at 16mm the image circle is 43mm (full frame)
 
Hehehe, He said telephoto.
 
Matthew - do you think the Tokina will cover 5K in 16:9 mode without vignetting? You said it almost covers regular 5K.
 
In another thread Sanjin mentioned that he thought the Tokina 11-16 breathed... I found myself thinking that I did not see much breathing. Here's a test I shot. 11mm Rack from 12 inches to infinity and back. f2.8, 1/250 shutter to compensate for the light.

That's an impressive lack of breathing...the focus just kind of changes...
