  • 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 :)

closeups using RED 18-50 on moving subject. This lens is turning out to be better than i had originally thought.

... This lens is turning out to be better than i had originally thought.

I remember when I had Gibby's #8 back in November 2007, I went by the Arri branch here in Ft. Lauderdale to finalize the deal on Ken's 8R and had the camera with me. Of course, they were very interested in the R1 but also asked if they could check the 18-50, and put it on their projector. They were very impressed - and these are guys that handle UltraPrimes and Masterprimes all day long.

What's really cool is with Birger or when Epic/Scarlet has the RED Canon or Nikon smart mount you can get this same optic for $419 as the Sigma Zoom Super Wide Angle 18-50mm f/2.8 EX DC Macro

http://www.bhphotovideo.com/c/product/463428-REG/Sigma_581101_18_50mm_f_2_8_EX_DC.html

This is an interesting rumor from Canonrumors.com:

"Too good to be true?
A cryptic message today said Canon is developing their first f/2 zoom. The broken english of the email said the lens would be a “short zoom range”. There was no focal length given."

Something like their 17-55 f2.8 IS in an F/2 (full stop more light) would be pretty cool - would probably have image stabilization too.

Nice stuff Johnny, I'm really looking forward to spending some time there with you next year filming all this awesomeness, but the more grabs you post, the more days I'm thinking of extending my trip by :-) Were you using a color filter here or just white balance? There are some orange tones that have that trademark URPro look, though it could be proper white balance or color correction...

Hey Rudi,
I just did a proper white balance then a one light in Redcine and lastly auto color/contrast/tone in photoshop for a quick frame grab. But you'll notice when there is a lot of blue water, the blue channel gets rather noisy.

No filters on the lenses. But one thing for sure, after reviewing the shots in raw and then color correcting, there's so much room to play with the image in so many ways.

You'll find plenty out here Rudi to keep you busy filming.
 
fun stuff Ross....did you put yourself in the water or shoot with pole attached or ?

I leaned into the water off the dive platform...given more time I would have got in the water......20 plus big tigers devouring a whale is a sight to be seen....:yesnod:
 
I shot pack of around 20 big tiger sharks today devouring a dead sperm whale...used the Duclos 11-16mm glass dome on Deep Red. Was extraordinary.....heres a screen grab.
Ross

Wow! That's very rare.
 
That's another misconception, but one with a happy solution to it. You see, underwater, you don't let your needs/actions dictate your focus, but vice versa. You adjust to the focus range that particular lens gives you under those particular circumstances. I.e.: the old Nikonos 15mm is in sharp focus from about 12 ft/4 mt to infinity at F8, and if you need focus closer to you, then you close down to F11 and you have focus from 6 ft away. So you learn to work within the focus scale of the lenses and position yourself and/or your subjects accordingly. The beauty of this deep focus imaging is that, in reality, as the focal plane moves away from the camera, images start softening up gradually, due to diffraction, loss of light and visibility, etc. So you never need to worry about what's behind your subject, and if you do, just move your subject until you have nothing but blue behind you, easy enough.

This works for most of the work you do underwater. But, when doing fictional work, where you need to follow a protocol similar to topside photography, say, rack focus, blur the background, etc, etc, then you indeed need to implement the same criteria you do on land. And that brings with it the need to have enough lighting as you do on land. Then things do get complicated, just the same as they do on land, and possibly more. But loosing focus on wide angle vistas, or for that matter, on close ups and macro, should not be a problem, just as long as you follow the focus scale on your lens, and the lens is properly calibrated of course :-)

Excuse me Mr. Hungry Bull Shark, but would you mind hitting your @#%ing marks next time? :D

Fun stuff. Thank you for taking the time. I'd love to dive with a camera some time.

Actually there were bull sharks as well but they didn't really count next to the tigers.

Nice. How exciting when you're no longer on top of the foodchain :hand:

Hey Pawel you would have loved it...I am sure:biggrin:

Wow - that is incredible. I imagine the footage is rather impressive.
 
Tokina 16-50 f2.8 lens

Tokina 16-50 f2.8 lens

Just came across this on another thread:

Tokina 16-50 f2.8 lens

It would be useful for underwater as 16 is wide enough (not ideal but sufficient) to give decent normal wide angle u/w but also enough zoom range at 50mm to do some macro on the same dive without switching. People use the 18-50 but that extra 2mm (12%) is a pretty big deal.

$549 at b&H by the way. Nikon or Canon

http://www.bhphotovideo.com/c/search?Ntt=tokina+16-50&N=0&InitialSearch=yes


could use on Birger or Nikon with iris control, but also might be able to talk duclos into a pl conversion.

Also, apparently this lens was made in conjunction with Pentax and some reviews suggest that it can cover a 1.3x sensor which would suggest that it can easily cover RED 5k.

Also has a waterproof coating:
WP Coating
WP (Water Proof) coating made of a special fluoride compound has been applied to the front surface of the lens through the use of a unique evaporation process. As a result, the lens offers excellent water- and oil-repellent performance and makes for easier cleaning should the lens be accidentally smeared with fingerprints or cosmetics.
 
Interesting...
Hope you can persuade Duclos to do a conversion, this lens would be perfect for the next step in the zoom range if it performs better than the RED 18-50

Amund:

I would guess optically it is as good and mechanically it would end up about the same as his 11-16.

I don't have a duclos conversion, but don't you have both the duclos 11-16 and the red 18-50? How would you compare them mechanically.

The tokina 16-50 is about $50 cheaper than the 11-16 so I would assume a Duclos conversion would be the same or a little less than the 11-16 conversion.

If duclos doesn't, I have a couple people here locally that might tackle it.
 
I only have the Duclos 11-16 and quite happy with that. I have considered the RED 18-50 but not gotten around to buying it yet. Mechanically I would say they are about equal, the Duclos maybe a bit more tight and more accurately machined (but that's just based on judging one sample of each).
 
Here's a frame grab from red one: giant group of mobulas (type of ray) schooling on the pacific ocean. I was shooting in shallow water something completely unrelated when these were spotted and we then chased them for hours.

Holy crap! Is that size of school normal? I would love to see it in motion. It seems they are flapping in unison.
