RMC Tokina 35-105mm f3.5-4.3 is a budget manual parfocal lens. Even in the old instruction they wrote about focusing with 105mm and then just going back to 35mm for accurate focus. I use this lens only for photos and often I focus with the long end when I want to nail the focus on the 35mm.
you can adjust the backfocus by shimming your FD-NEX adapter, it'll be in focus at 35 and 105 but drift slightly in between
need to test that ! thanks
@@MathieuStern I think there is an option to adjust the back focus on the 35-105 Canon FD itself.
When I remember correctly you can unscrew some of the plastic housing to reveal several other screws with which the distance between the glass and the mount can be adjusted...
@@MathieuSternyep... I just checked. Three tiny Philips screws that hold the ring that says "35-105". Unscrew those three and you can slide the ring up under the zoom ring, which reveals six Philips screws...
With a bit of tweaking I believe you can get your Canon FD to be parfocal even "wide open" at 3.5
@@LasseDippelright, flange distance is the key, but even being set right, it can't truly help this lens. For some reason it's ALMOST parafocal, but in between the ends focus drifts unevenly. That's clearly a design flaw(
Also there's one eccentric screw under the plastic/rubber band on the zoom ring. It's accessible the same way as collars. I tried to rotate it back and fourth, but it doesn't change anything focus-related. Most probably it's for floating element centering. Don't spin it if you think it's an idea)
that bird bath shot was perfectly timed
The price is right…😂 the Angenieux 45-90 f/2.8 R mount is parfocal, if you sync the zoom with clear image zoom (fx6) you have a 3x with vintage sweetness. Then there is the Leica R vario 35-70 f/4, parfocal, also a Nikon similar to the Leica that was selling for $85 last I looked. The three vintage mentioned can be pared with anamorphic adapters for more fun.
I just got this vintage lens! I haven’t had much time to REALLY play around with it yet but I quite like it! My only gripe is that the focusing ring is the shortest I’ve ever dealt with. I feel like it should have more focus points, but that aside I love the photos I get from it and I’d love to try video on it very soon as well! I also use the 7artisan spectrum/vision cine lenses and love them! Big fan of the company.( But I’m also a hobbyist so they’re more than I’ll ever need 🫡)This was an interesting comparison video 😊
Camera manufacturers might be able to make varifocal lenses work like parfocal with some sort of autofocus compensation. If lenses were made to a tight tolerance, the manufacturer could have their cameras be able to set focus once manually (or automatically for those who want) and when you zoom the camera will know how to adjust the focus according to the focal length
Given that the lens is actually designed for the sensor of the camera otherwise all specifications are void which the camera can not compensate aka the infamous and technically wrong term "crop factor".
Unfortunately, many people are talking about this lens as if the Fujinon MK Zooms, and the DZO Pictor/Catta Zooms, the Sirui Cine Zooms don’t exist. Sure, you can say that “non-budget lenses” start at $2500 but really you’re not even $1000 off that number for the lenses I mentioned. Used, I could get a Fujinon Zoom for $1800. Not sure how parfocal these are but with focus marks, you can pull focus during a zoom.
Sorry for the rant, but on a positive note, a non-parfocal vintage substitute for insanely cheap is the Nikkor 50-300mm f4.5 AI-s. It’s not parfocal, but for large zoom pulls outward, the focus is close enough on the wide end.
The Fujinon MK are perfectly parfocal, as they have an adjustable backfocus.
And with them being
In your professional opinion, where do you suggest I send my old film cameras to get fixed? I have an old zenit e with a hellos 44 lens, and the shutter curtain is stuck, and Google isn't giving me any help. Do you have any suggestions as to where to send my old film cameras to get fixed?
you could contact Hostophoto on instagram, but he is in france
Way better is the Apollo or Schneider Variogon 18-90mm f1.8 which works great with the black magic original (covers super16). It would be cool if they made this lens again for mft format - wonder what it would take to widen image circle!
How do modern STM lenses (like the Canon EF-S 55-250mm f4-5.6) stack up against vintage close-to-parfocal lenses like the Canon FD mentioned here? The STM motor uses autofocus while changing focal length. Isn't the result the same as that of a parfocal lens, just using different technology?
Parafocal c’est très important pour filmer, et l’autre point capital aussi c’est que le changement d’ouverture de l’objectif soit libre et que l’on ne passe pas d’une ouverture à une autre par des crans. Je ne sais pas si cette autre particularité porte un nom technique.
They went very large on the front letters. 😂 That's good. I need at this age but it's funny.
Could you try building a large format bellows camera from scratch and capture video through it?
I could, do you want to sponsor the project ?? :))
@@MathieuStern
I’m not capable of sponsorship. You look to the Intrepid company. They make incredible large format cameras out of wood. Maybe they can sponsor you?
@@MathieuStern
Also, thank you for the reply! 😊
@@MathieuSternpin his post and maybe you'll get a call from a sponsor. you never know :P btw I would like to see that too, and you're the only person that comes to my mind that can experiment with this :D
Very interesting video, but there are some relatively cheap parforcal lenses, like the Lumix G Vario f2.8 12-35mm
the fact that it's called Vario ... means its a varifocal lens
@@MathieuStern that's the brand name for Panasonic zoom lenses. I've used it extensively for shooting and it exhibits accurate focus lock at f2.8
Savez-vous quand le zoom de 7artisans sera disponible sur le marché ? Je suppose que vous l'avez eu en exclusivité.
oui en effet, je ne sais pas par contre quand il sortira, peut etre qu'il ont changé des choses depuis la review
@@MathieuStern Merci pour la réponse. J'ai hâte de l'essayer quand il sortira
Pretty amazing
It gets a little bit darker when zoomed in.
so camera lenses can be nearsighted as well? I wonder if glasses can be used for DIY equipment at this point 😆
That Gizmo crash zoom was 🤌🏾
I love the Canon FD
I hate all Canon FD lenses 😂
Is the most annoying mount ever. So much that I sold them all. Ok, it's just me maybe, but I found the mount unreliable, unnecessary complex, and the adapters problematic. Far different from my Minolta, Nikon or other old manual lenses.
When you bring this lens to B&H (as I did to get Sony trade-in rebate) they will ask you if you want them to recycle it. 😁
lol. put the main thing aside. MAN, I like your accent :).
Yes.
No it can not, no matter how much you go back and forth with it.

As you say, it's a budget lens.I teach cinematography classes and I regularly see students who want to purchase such a cheap lens. . How long will this lens last on a film set? Samyang started this cheap (fake) cine lens mania and now many Asian factories name their cheap lenses with the magic word cine
It's the Far west right now for chinese lenses, some are great and some are a clear cash grab, everything is made fast without a real road map.
but in another hand ... a lot of people can't afford $20k lenses for learning filmmaking
It $1599! How long does it need to 'last'?
@@FFVoyager thanx to our throwaway society not very long
@@noudsmeets but how long? Long enough to shoot a film, get experience and benefit from using it? What's that 'worth'?
You don't have to get one, you don't have to use one. But you certainly don't need to whine that they aren't any good - especially if you haven't bothered to use one!
@FFVoyager working >25 yrs as cameraman and dp is enough for me to advice my students not to buy one and or rent a decent cine lens or use a vintage still image prime. But we have schneider Kreuznach cine lenses at our school so they learn the difference in quality
Cine lenses are a bulge of glass. Why are photographic lenses much more compact?
They’re correcting for a lot more. Parfocality, chromatic aberrations, vignetting, sharpness etc. modern photographic lenses tend to prioritize only a few of these things in their corrections while leaving the rest up to lens profiles and autofocus. Older photographic lenses didn’t do this, but all this correcting also results in expensive, complex formulas so they also would pick a couple of these things to focus on to keep cost and size down.
Optical failures are corrected in with digital profiles. But for this every frame have to run through a correction algorithm.@@questioneverything680
