Originally posted by Rondec Wow, those are some of the ugliest lenses I've seen. I'm sure they are great to use, but I don't like their look at all.
My point wasn't exactly their look
which, by the way, is quite common among cinema lenses.
Originally posted by Kunzite 35mm, 50mm, 85mm f/1.4 (T1.5) - those are standard lenses, there's no reason to assume the optics were designed by Pentax/Ricoh Imaging.
Point #1 is the fact that the next three D FA★ and the first three Tokina Cinema Vista lenses share the same focal lengths and aperture:
- the next three D FA★ are said to be a 35mm ("Large Aperture Wide-Angle Single Focus Lens" on the roadmap but asahi man said it's a 35mm here, here and here), a 50mm (roadmap + mock-up) and a 85mm (roadmap) f/1.4.
- the three available Tokina Cinema ATX lenses are a 35mm, a 50mm and a 85mm T/1.5, which is equivalent to f/1.4.
Point #2 is the following: how could Tokina possibly propose $4,500 24x36 cinema lenses without sharing the development costs with photo versions, like all their competitors?
Until these Tokina Cinema Vista lenses, which cost $4,500 each, any and all full-frame cinema prime lenses under $5,000, i.e. entry-level lenses
(*), have been rehoused photo lenses to lower costs:
- Canon Cinema EOS lenses derive from their EF lenses
- Leica M 0.8 (cine) lenses derive from Leica M lenses
- Mitakon cine lenses derive from their photo lenses
- Samyang Cine and Xeen lenses derive form their photo lenses
- Sigma Cine lenses derive from their Art lenses
- SLR Magic cine lenses derive from their photo lenses
- Tokina Cinema ATX lenses derived from their ATX lenses
- Zeiss Compact Prime CP.2 lenses derived from their former Classic ZE/ZF.2 lenses and CP.3 lenses derive from their Milvus lenses.
(*) Cinema-specific lenses like the Zeiss Ultra Prime and Master Prime lenses are much more expensive: between $12,000 and $20,000 for Ultra Prime lenses and between $20,000 and $30,000 for Master Prime lenses.
These three Tokina Cinema Vista lenses are presented as purpose-built for cinema, with specific optical formulas: 14 elements in 13 groups for the 35mm T/1.5 and 13 elements in 10 groups for both the 50mm and the 85mm. They have no equivalent in the portfolio of Tokina photo lenses.
It's difficult to imagine how Tokina could:
1. design and launch five brand new lenses (the three already available plus a 18mm and a 25mm T/1.5 said to follow shortly) in a short period of time with their limited resources and
2. propose a competitive offer in the highly competitive (and more and more crowded) market of entry-level full-frame cinema prime lenses
if their lenses were dedicated to the cinema market with no photo versions to share the development costs with.
Point #3 is the
report made by Pentax Forums staff on February 1st, 2013, it being the first solid rumour / confirmation of what was to become the K-1.
Originally posted by Pentax Forums staff: A Tokina employee revealed to us today at CP+ that Tokina has renewed their discussions with Pentax about reviving their lens collaboration as of late last year.
According to the employee, Pentax is reportedly developing a full-frame camera (he claims that a prototype already exists). He stated that all lenses developed will be re-branded under the Pentax name as it had been done in the past.
Talks had previously stalled after the Ricoh takeover in 2011, but Pentax has requested that Tokina still show new lens designs for possible collaboration. However, no Tokina prototype lenses have been made for the Pentax full-frame yet, and no deals have been finalized.
Point #4 is something that I just heard which could explain the current delay. The D FA★ 50mm f/1.4 would be fitted out with a new type of focus motor. The development of this new motor would be / would have been taking longer than expected, some difficulties being / having been experienced and Ricoh Imaging being uncompromising about its performances.
Indeed, if the optical formula is an off-the-shelf one, the autofocus system as a source of delay sounds plausible, even more so when you remember the tip received by Zygonyx:
Originally posted by Zygonyx Good news : DFA*50 and 85/1.4 shall come within a short time-frame in 2018's first quarter.
Originally posted by Zygonyx Both in a short time-frame means at worst 2-3 month btw the 2 releases.
I'd think it is 80% reliable.

Are these just coincidences? I leave it to the reader to judge.
