Hello everyone. My name is Enrique, I am from Argentina and I have been a director of photography in film and advertising for about 5 years. I am interested in investing in a kit of SLR lenses for make them rehoused cinema lenses, since I am advising investors in a future rental house with which I am going to work.

I've been thinking about the following options:

Super takumar
Pentax M
Pentax K
Pentax A
Pentax Limited?

What is being more difficult for me is choosing which of those kits would have a better 35mm f2, or a better 28mm (f2 or f2.8). I am also having a hard time choosing which lens below 20mm would be better, considering the speed-IQ ratio. The latter is because the kit will have to be used in s35mm cameras apart from the new full frame cinema cameras.

Regarding the 50mm and 85mm, I understand that in general they are all quite good, but it would also be interesting to know which are the best, or most mythical.

I also find the option of limited lenses interesting, although there are no fast lenses below 31mm.

From what I have seen in the different providers of the rehousing service, Pentax are not frequent. I am even having a hard time finding Super Takumar rehoused (which is not the same as declicked and cine-mod).

Anyway, it seems like a good exercise for the forum. I did my entire still photography career with Pentax, and now I want to bring some of that legacy back to my career as a cinematographer.

Thank you very much in advance for your opinions on this matter. Greetings!

rehaused Is not a word that’s commonly used in my experience in America. Reading on the web it seems like a form of refurbished?

Many videographers like the super takumar, SMC takumars, and the K mount takumars for sharpness and some for their flaring and flares. I have the super takumar 35mm f3.5 which I love, but others love the SMC version even more. Anything M or later will have different flare, ghosting, etc, due to advanced and modern coatings. That said, the 24mm f3.5, 28mm 3.5, 55mm f1.8 and 50mm f1.4 Super Taks are almost legendary for their performance for stills and digital video. Suggest you read the lens tests here on this sight, and read how they perform with aps-c sensors and then how they perform for those with the FX sensor K1 and K1 mk. 11 to find the gems among them. Cannot speak about lenses that are wider and more tele, but there are also 85mm and 135mm Pentax lenses that are super and there are also 18mm, 15mm, and 20mm lenses that are also considered superb for digital photography, if you read the reviews. Great small wide lenses for super 35mm would be the limited 15mm and 21mm apsc lenses, if they can be outfitted with apertures as part of their cine-mods. Oh yes, and then there are the great many limiteds which I do not (yet) own...
In any case, good luck with your endeavor and reviews of lenses. Suggest you make a small or other contribution to this site for all the great information that has been assembled for all members...

Rehousing is when you take a still photography lens (or any particular lens, can be a projection lens or a particular old cine lens), and you use the glass of it in a Cine Lens housing.

For example, I leave you 2 pictures of the same lens, a Sigma 18-35mm f1.8/t2.0. One is the original, the otherone is a third party rehousing (there is also an oficial rehousing). When the rehousing is made in a zoom lens, it could also include parafocal mecanism.

And the spelling is different which explains why I wants was not able to find information on it. Thank you.

Exactly like this, but I would like to know if instead of Takumars, would you recommend another line of lenses, such as Pentax A.

[UncleVanya]

My personal favorite manual focus Pentax 85 is the A* 85 f1.4 but it is rather expensive. The Plain old K series (pre-m, pre-a) is probably the best built, but with rehousing I’m not sure that’s as big of an issue. You could mix and match... getting the best optical example of each focal length.

Rehousing of lenses is typically not done for individual lenses - a single copy of this and a single copy of that lens. Getting the right lens is not easy and rehousing is a difficutt and expensive process.
The questions is whether you are going for the vintage look of older glass or depth of field specialists or a line of special glass like FA ltds. Typically a line of 3-5 lenses make a full set, the 3 FA ltds just cover a certain range, but no real wide angle. I am sure Zeiss glass is rehoused offering a wide range of modern options.

Exactly. The idea is to add a vintage lens kit that is not so common in the market, such as the Canon FD, Nikkon AIS, Zeiss Contax, Zeiss ZK, Leica R, etc.

If the FA limited series had a ¨fast¨ 18mm or 20mm for Full Frame it would be a dream. Rental houses are looking for old rehoused FF lenses, as there have been many film cameras on the market in this format, and modern full frame cinema lenses are exponentially more expensive than s35mm lenses.

For now we are thinking about the Pentax A, 28/2, 35/2, 50/1.2 and 85/1.4 extendable in a second stage to 16/2.8, 20/2.8 and 100/2.8 macro.

The 16? I’m surprised as that is a fisheye that you didn’t pick the A 15 f3.5 as the ultrawide.

The Pentax A 28 f2, 50 f1.2, and 85 f1.4's are all loved lenses by Pentax shooters. The 20 f2.8 is also very apricated in a system that doesn't have as many wide angle options as other systems might offer.
