  • 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 :)

New Sigma 18-35mm f/1.8

Ok guys, I promised to test out the lens, but I didn't have enough time to do it properly. So I refrained from posting anything at all because the info is not worth very much.

But not answering at all is a shitty attitude, so I decided against my better judgement to post anyway ;)

I did a quick "hold iPad with white screen in front of lens" thing and zoomed in just to have anything to look at. The light from the iPad was too strong, so the vignetting seems worse than it did when filming.
The lens is perfectly usable on Dragon @ 5K FF. When shooting 6K FF it vignettes @ 18mm but it gets better at around 22/25mm. At 35mm I only noticed light falloff. Of course when using 6K HD or 6k WS it's less noticeable and disappears even quicker (at around 20mm already)

For what it's worth, I will continue to use it if I get my hands on another Dragon body. To me it's useable even at 18mm @ 6kFF. You just have to either accept the vignetting or deal with it in post. But I like the look the way it is.
 
These aren't great but here are some snapshots.
All highly compressed 17:1 / 16:1, 800 ISO, no filters, no sharpening and no grading or retouching done whatsoever. Shot with the old OLPF.

Thanks for sharing Patrick! Fully usable at 5k is fantastic and already "good enough" but you are right, it holds up better than i expected, very usable for 6kWS, depending on content or with a little more crop and/or post-correction even at 18mm. 6kFF, hmmm, i'm not so sure, but with carefully composed shots it might work if there is darkness in those corners anyway. Custom resolutions, if they're coming, will probably allow us to find the maximum between 6k and 5k.

All in all, this lens is a little secret weapon.

Reminds me again, lens-correction profiles a'la DXO Optics would be a great addition to RCX. :)

Far more importantly, Patrick what font is that on your stills? :)

Bob is pretty good ... though I used the "thin" and not "ultra light" in this case. The ultra light is even tougher to read when overlaid on busy images.
The Helvetica Neue ultra thin and light are almost being overused at the moment, so I usually try not to use it.
I mainly picked it, because RED has been using the Ultra Light since it moved away from "motor" to "helvetica neue" when the print ads came out. ;)

BTW if you are ever wondering what font is being used, this often helps:

This would be great. It's almost weird that adobe didn't integrate it yet. But I'd rather have RED do it so it's not adobe dependent ;)
 
I never tried that Cinematics version, but I do use Cinematics gear rings on my 18-35, 35, 50 Art lenses and I like them. Sturdy, light weight, improves throw.

BTW, I've been waiting for the rumored Sigma 85/1.4 but it hasn't been announced. Could somebody recommend a temporary 85mm lens that will match the other Art lenses in the meantime?

Has anyone see or used the Cinematics version of the Sigma 18-35? http://www.ebay.com/itm/Customized-...63646447?pt=Camera_Lenses&hash=item41829487ef

Can't really afford the GL version and I'd like to get one of those fast Sigma zooms.

Michael - Cinematics has an interesting approach to "re-housing" lenses. If you search Matt Duclos' blogs he discussed them awhile back. They don't really re-house, they just add their own housing over the top of the existing one. So, what you get for the extra $800 or so is a standardized front end and a slightly longer focus through (only because the ring is bigger). You'll notice they don't have an aperture ring; they are internal focus only. And they look cool. Not saying it's a bad thing; I have 3 Canon lenses with housings by these guys. They work well. But, it's nothing like the GL Optics version which has been completely torn down and genuinely re-housed. I have one of those, too.

To be honest, I think you might just buy the standard version at $800 or so which is exactly the same optics and the same mechanics. You could even have Duclos "cinevize" it for about $250. Probably a better deal. :smiley:
 
Thanks Terry. That's probably the right approach. We rented the standard version and I thought it was a great match for the epic. My only real issue was having to manually calibrate the focus system every time we put it on the camera. Having hard stops on the focus would make it easier to work with. Unbelievably that little lens is not only parafocal but seems to have a nice linear zoom pull. Can't wait to see what Sigma does next.
 
So I've been looking EVERYWHERE and can't seem to find an answer:

Since the new sigma 18-35 has an electronic aperture I can't use this on my R1MX, but -- I have an Allstar adapter -- does one of the adapters have a manual aperture built in? Does anyone know of a way for me to use this lens with my R1 without having to buy a birger mount, sell off the R1, or buy a cine-modded lens?

Thanks a TON in advance!!!

happy holidays!

PS, Would also want to do with the tokina 11-16.

Why not get Nikon versions of the lenses?

Thanks Patrick!
 
Since this was bumped... I keep trying to convince myself to sell this 18-35 and get the 24mm/1.4 Art, to have a set of 24/35/50 all at F/1.4.
But based on reviews, I really can't justify it if the 24mm doesn't look as good at F/1.4 as the 35/50 and it vignettes more. And if I go FF35 sensor at some point, my 35mm/1.4 Art might be all I need.
Anybody have to make that decision?
