  • 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 :)

Birger Canon Lens Database

For what it is worth (I think quite a bit), Ken Rockwell is not very fond of the Tokina 10-22, but he loves the 11-16 (as do I). I have not ever seen or heard anything about the Sigma 10-20. I'll have to look into that one. Rockwell is very fond of the Canon 10-22, however. I believe he likes it even better than the Tokina 11-16.

Stephen: When I did test shots with both the Canon 10-22 and the tokina 11-16 I found the Canon a little sharper at the corners. Canon also is 10 percent wider, but the tokina is a half stop faster at the wide end. But they are both very good lenses.
 
Thanks for that report, Michael.

I have the Tokina. . . at f2.8 it is the slowest lens I have (along with the 200 and the 16-35 zoom). Would you dump it in favor of the Canon 10-22? Or just keep the Tokina?

Thanks.

The difference is very small and I certainly wouldn't do it if it cost much to switch. I think the basic decision of whether to go 10-22 or 11-16 is how much benefit you get with the extra 10% wide or how much the extra 1/2 stop helps you.

For most normal feature, commercial, or corporate type stuff the extra .5 is probably more important but contrary to what a lot of people think, I generally don't need the extra stop for my underwater stuff - typical daylight situations are in the f8 or higher range, and I use lights in night or borderline situation.

Bottom line for me was I had both for evaluation purposes but then didn't need them so when an opportunity came to sell the Tokina, I did. But if he had wanted the Canon instead, I would have sold it.
 
Fair enough. . . I'll probably keep the Tokina.

Thanks very much.

Sigma 50mm f1.4 & Sigma 30mm f1.4

Sigma 50mm f1.4 & Sigma 30mm f1.4

The Sig's are great glass. As of right now they don't work with the Birger Mount or at least mine. I will be sending them down to Erik. The issue is when an attempt to calibrate the lens is made, either cable or bluetooth, the impero looses connection.
 
"Canon EF 24mm f/1.4 USM L is one of many ultra fast fix focals in the Canon lens line-up - seems as if Canon is really enjoying to go to the max in this niche. Regarding its release date it is obviously a full frame lens. On APS-C DSLRs it has a field-of-view equivalent to a classic ~38mm lens so it can be considered as a moderate wide-angle lens here."

I would like to try this lens out in the future.
 
I'm possibly misunderstanding your question/comment Shawn...

Correct that 24 1.4 L is widest super speed lens.

Not correct that it becomes a 38.

Its a 24 and would offer the equivalent field of view that a Master Prime 24mm or Super speed 24mm PL mount lens would offer.

The Canon 10-22 or Tokina 11-16 offer extraordinarily wide options to S35mm cinematographers. 16mm and/or 18mm are typically the widest lenses used in typical dramatic filmmaking.

And it will cover not only epic-x but epic full frame as well. All L series lenses are full frame lenses. Canon does not give the L designation to any ef-s lenses (APS-C/S35) even though lenses like the 10-22 and 17-55 IS 2.8 are essentially built to L series quality specs but do not get the designation because they are designed for APS-C/S35 sensor size.
 
I don't get it. . .

I don't get it. . .

Shawn, why on earth would you care about aperture noise at all? You can't adjust the aperture while you're shooting, anyway! I mean, you're limited to 1/3 stops, and that's immediately noticeable and therefore unusable for actual continuous-shot footage. Or did Erik find a way to make our iris control continuous??? Surely that can't be true.

Paul, Michael, Stephen, I seem to have been dream posting. Sort of like sleep walking but in this case writing things that make no sense. I have cleaned up my posts ;).
 
We own that L-Series 24mm MKII f1.4 and it's a very nice lens to have when you're shooting in low light. Blindingly fast. Looks terrific.

Actually, I've found iris racking to be very smooth on most of my primes. Hit the I button and press calibrate if you haven't tried it. He really smoothed it out in one of the firmware updates (maybe an Impero update).
 
Hmmmmmm. . . this is interesting, Joel. . .

What builds are you running?

Thanks!

Stephen
 
Anyone tried the 20-35L? Some say it is sharper then the new 16-35's.
 
Just to break it up a bit, here's a still taken from a 4.5K shot using the Birger mount and Canon EF50mm f/1.2L USM prime lens wide open (at 1/50th second shutter ISO320):

B001_C037_0218R8.0000237c_s.jpg


I added the grain and look in post, the original image is quite clean given it is shot using normal Mysterium sensor at night.

Resized to 1920x823 to mimic Blu-ray Disc output size (it was a test shot done for a movie coming up).

Love the look of this lens and it works perfectly with the Birger mount :)

Cheers!
