Scarlet FF35 vs Epic X

Question

Question

Looking at Roberto’s laundry list if Canons Lenses from 14mm to 180mm, and then looking in the web, I found that the Canon Lenses to be T1.5. Can someone clarify the Canon lenses for me? The information on these lenses seems to be rather sketchy.

There are really hundreds of lens test sites and reviews for Canon lenses on the net, but here is one rather usefull one;
Most (or all) of the primes with lens data, review and average price.

http://www.the-digital-picture.com/Reviews/Canon-Lens-Reviews.aspx

Use the < > tab at the top to see the zooms.
Click on the ISO 12233 Crops in the link for each lens. There you can compare two lenses shot on a chart.

All Canon EF lenses covers FF35. EF-s might cover RED Epic/Scarlet s35.
All lenses marked II is the newer edition of the lens.

Note also that some of the Canon L lenses have a Canon equivalent that is much less expensive but nearly the same optical quality.
Example is EF 50mm f/1.2 L USM $1,400 vs. EF 50mm f/1.4 USM $400 vs. EF 50mm f/1.8 II $100.

In addition there are some Sigma and Tamron lenses that performs nearly identical to the Canon equivalents, but with a lower price.

Well I looked up the K-35 Canons of which I had never heard before and look like no canon I had seen before. I thought these were re-housed Canon glass not still lenses in their natural state.

I have the K-35s. They are indeed rare and quite unknown in the film world. They're amazing lenses to say the least.

Not much is known about them other than the fact that Canon produced these lenses for cinema use from the late 70s to early 80s. They are not rehoused still lenses.

Canon made PL sets and BNCR sets of K-35s. I bought a BNCR set and had them converted to PL by Jacek of Optitek in LA.

Here's some more info on them,

18mm T1.5 Close Focus:1foot Weight:2.64lb 110 degrees rotation
24mm T1.6 Close Focus:1foot Weight:1.7lb 110 degrees rotation
35mm T1.4 Close Focus:1foot Weight:2.2lb 90 degrees rotation (shortest rotation)
55mm T1.4 Close Focus:2feet Weight:1.5lb 210 degrees rotation
85mm T1.4 Close Focus:2feet Weight:1.7lb 240 degrees rotation

They also have an 18mm T2.8 and I believe a 135mm.

According to Canon's website, http://www.canon.com/about/history/03.html "The K-35 series of lenses for cinematography wins an Academy Award from the U.S. Academy of Motion Picture Arts and Sciences." in 1977.

Oh yea, they are also Full Frame 35... not the 18mm, but the rest are..

Can you tell I'm a fan? haha

nice! so how much are them babies selling for? bummer that the 18mm does not cover ff35! How large is the image circle?

I remember that footage you posted with the Canon K-35 and the RPPs. The Canons seemed to be rocking it. Same question as Tom, how much for the set and the conversion to PL?

 

[Rick Darge]

Well Spinning Mirror had a set for sale about 6 months ago. They were PL mounted and he got $18,000 for the set I believe.

I've seen BNCR sets with the 18mm T1.5 range from $9,000-$15,000 depending on their condition. The sets that have the 18mm T2.8 are usually quite cheaper, $7,500-$10,000 range. I know Stone Cine had a set for sale but he wouldn't budge on his price back in Feb. 2009. There was a K-35 BNCR set that went for $10k I believe a few months ago.

Conversion varies. I paid $5,050 to have all 5 lenses converted to PL by Jacek. If you're patient and have the time, it's worth it. Key word here is patience as it takes 2-5 months to complete the conversion. There is another guy in the UK that supposedly converts K-35 lenses as well. I'll try to get his name.

So yea, you're looking at $16k-$20k~ for a full set right now. I wonder if this price will drop? My guess is not really since these lenses are future proofed for FF35.

 

[Rick Darge]

Jacek told me that the 18mm was roughly 34mm image circle. So plenty fine for 5k. I agree though. Bummer. I wish the 18mm was FF35 because it's my favorite lens in the group.

 

[Rick Darge]

Les Bosher in the UK is the other guy who does K-35 conversion apparently.

If the sensor on the Scarlet was a FF35, would the EPIC X still have a superior picture to the scarlet?

I don't think Redcode 250 @ 5K will be better than Redcode 100 @ 6K when you take into account the higher bit depth (16bit) and larger pixel size (6.0 micron) of the Monstro.

I forget to take into account the image circle of many lenses like the RPP's.

The image circle of most of the RPP's will only cover about <4.5K on the FF35 compared to the full 5K resolution of the Epic X.

We may as well also consider that we should compare the two pictures after they have been downscaled to 4K. Since this is probably the max res that most will use for final output anyway.
