  • 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 :)

S35mm afordable zoom, which would you recommend ?

I have used all of the above.

They are all big heavy lenses which will also require long rods, lens support, and an extended dovetail.

The Cooke's weigh in at 13 1/2 pounds while the RPZ is a little lighter at 10 pounds.

By the time you fit a matte box, filters, zoom/focus motors, support, you are looking at around 16 pounds of weight on the front of your camera.

Close focus is about the same on all of them, at around 2'4" for the Cooke's and 2'3" for the RPZ.

Do you need a single production zoom, or would a pair of smaller focal range zooms suit you needs better?

I need a single production zoom that can work in a variety way.

I have a lots of still lens(sigma arts prime sets) and still zooms. If I needed the prime sets i usually rent.

but I always wanted to own one zoom lens...

also the price seem pretty good as well :)
 
The Cooke 18-100 is very nice but big. If you can swing it, the new Cabrio 20-120 looks like it has potential and will be released later this year for around $15K.

For what it's worth, Alan Gordon has a handful of low cost zooms for sale right now.

for sale, or on sale? :)
just on there website? or is there a special in an email or something?
ive always found alan gordon to be over priced, especially now a days.
 
What about price....??? The Cooke can be had for about $10K....but the RPZ can be found for much less. I paid just $3K for mine....and while as everyone says, it is big and heavy, it is a lot of glass for not much money.

What's distortion like?
 
I don't see much in the way of distortion in mine...(RPZ 18-85, but maybe I don't know what I am looking at?)
What i do know is that it appears to be a well built unit and the pictures are nice, some even say there is a bit of a Cooke look. I don't have enough experience to know whether that is true or not. I think the failure on the RED lenses was that they didn't cost enough, (the perception that because it is cheaper it must be crap is in play here I think) and this thing weighs 10 lbs. However, a Fujinon 18-85MM T2.0 Premier weighs 15.5 lbs and costs $87,300. It is one stop faster but....

Edit: I am not saying the RPZ is a great lens. What i am saying is that they can be had pretty cheap and they make decent pictures.
 
This thread got me looking into some lenses. How is the cooke 20-60? Only 3:1 zoom, but weighs 7 or 8 lbs and is 10 inches long. Anyone have footage with dragon? I found one for sale for 7k.

i was always curious too, i asked my camera house in LA that deal mostly with vintage lenses and the response was that they tested a bunch and they were always too soft, but id like to test one myself, that price seems good, ive seen them from 6-9k.
if you dont buy it let me know, i might :)
 
Yeah they seem hard to find, I emailed them as I'm not sure if it just an old for sale post or not. From what I have read the 20-60 and 20-100 are very similar optically, maybe giving the edge to the 20-60, and footage from the 20-100 that I have seen is quite sharp. I would love to check one out.

oh, is it from visual products? then yes, that is like a 5 year old google indexed page :(
 
Cooke 20-100 has smaller image circle than 18-100, from what I understand.

Canon's new Zooms look really appealing (30-105) for the price.

As does the Zeiss 28-80, which is full frame...and by all accounts superb (and not that big or heavy).

I can can attest to how beautiful that glass is!!! I've tested the 28-80 several times now and each time it has absolutely blown me away!

Also, perfectly sized and weighted for an Epic Dragon sized, cinema package. When my company finishes paying off our DRAGON, it'll probably be the next major purchase we make!
