  • 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 :)

The Sigma rumors

Anybody found a way to use add filtration to the 20mm besides filters in a matte box on rods?

Not specific to this lens, but, I have a rokinon 14mm which has the same type of wide angle built in hood with no threads. I measured the inner diameter, and an 82mm stepdown ring fits perfect inside the hood, I gaffed around to hold it in and cover the gaps that would let light in. Works like a charm with my 77mm screw ins. If using full frame it will vignette, but on s35 I'm good to go.

4x5.65 filters and gaffer tape! ;)

I've used this DIY approach to rig some NDs on some Aerials in India in may (on a 15mm Zeiss ZE) worked a charm! ;)

If you do it right it's relatively fast to change filters...

Gaffer tape has to be good btw, not cheap ones or old...too sticky
 
Sigma cine lens will cost you 3-5k I guess,

In a mean time, you've go choice to buy Otus 28mm, 50mm, 85mm with loooong throw focus with similar price.

Which one do you prefer between optical quality and proper cine lens? (It's like Rokinon xeen lenses vs ziess Still lenses)

I like sigma much more than Otus, it's because, ziess generally make bad wide angle lenses. Never liked 28mm and 24mm (In this case, I am not talking about Otus.) On the other hand, sigma made 20mm 1.4, 24mm 1.4, 35mm 1.4 in a very decent level.

I was so shocked when sigma announced 20mm 1.4!!!!!! - In terms of super 35mm sensor equivalent lens, 20mm 1.4 is refering to 12mm 0.98 - 1.1-1.2T I guess. This is just a shocking. I always wanted to make shallow depth in wide angle lenses, and finally the dream came true.

85mm and 135mm will be come out eventually, and we all are expected. In fact, I am hoping sigma makes another 16mm 2.0 - Which is almost impossible, but why not dreaming. --- Seriously, am I the only one person who gets so excited about 20mm 1.4?

However, due to purchase on Raven and Canon EF wireless focusing system (Foolcountrol), I would rather not investing sigma cine lens. If the budget allowed me, I would rather use ultra prime, master prime, or even anamorphic lenses.

Of course my A.C will complain me, and I will be stressed about it. But, that's the reason I am hiring him for, ain't I? If my A.C complained me too much, I could use my manual focus cheapo lenses (Mamiya 645, pentax 645 lenses, pentagon six lenses) It's all still lenses that has long long focus throw, and without several really expensive rare lenses (MAMIYA 300mm 2.8, Mamiya 500mm f4.5m, and several pentagon lenses.) I have three sets of these lenses that cost me less than $10k for personal collecting and low budget usage, it's good for what it is.

In that case, I will be sticking with sigma canon mount still lenses for a while, and invest on hasselblad lenses (Currently, I own full range of mamiya, pentax 645 lenses from 24mm to 300mm) - Yup, after 8K vista version sensor, we all know that sensor will be getting bigger and bigger...- which is kind of making my life tougher to catch up - one day we will shoot (1.5 times bigger sensor than VV sensor 16K) (2024?)

We all will be cried again when the sensor gets larger, and we know this will be happening near soon.
 
Zeiss make the best wide angle lenses. Can't beat the super wide master primes, 15mm cp2, and 15-30cz are all outrageously amazing.

according to http://www.abelcine.com/fov/ 20mm in ff35 would be 17mm in 6k hd and 15.2mm in s35 film 16x9

The exciting thing about the sigma 20mm is that it will likely cover VV 8k

My SIgma 20 1.4 is awesome for the price. Find me another lens that is that wide and useable wide open, actually very good at 1.4, that isn't at least $10K, I don't know of one, maybe there is something I haven't heard about yet.
 
Really should try the opitron 2 with the Sigma Art lens. Gives you amazing focus control, so you get cine style control on still lenses without having to do a costly conversion. For a one time cost under $3,000 you get a wireless focus control. Just got mine, but will be using this on every shoot.

I've been pushing this since 2007 with the Birger Canon mount - optitron is even better - totally pro solution.

Gunleik has examples of the Opitron 2 with a bunch of lenses. I have only tried it on one of my lenses so far, but feeling the fine tuning were you have a large area of the circumference where you are in focus compared to using the lens focus and it is a tiny area that is hard to hit drives home the huge advantage this tool gives you. The canon motors can be a bit load, but the Sigma lens are suppose to be much quieter. I have the Sigma 30mm Art I'll try when I get back from vacation.

How do they get "faster than 2.8" from that picture?
Click to expand...

I'm guessing it's because it looks like 70-200 zoom shape and it's described as another "worlds first" so what could they do with a new 70-200 besides make it faster than 2.8... It fits with their previous "firsts". I'm gonna guess a ~45-105 f1.8 to go with their 18-35...
 
As long as we're dreaming....

How about something similar to, yet faster and sharper than the Canon 24-105? ...Something to compete with the Fujinon Cabrio 19-90 and the Canon 17-120, for a tenth the price?

Too much to ask?
