Budget ultrawide lens

Dear all,

after watching the video trying to find the lens behind the movie 'fallen angels' i'm intrigued to take photo's like the ultra wide camera work in the movie.


Preferably in low light as I do regular urban explorations.

If someone can suggest a budget lens options for Pentax K I would be happy.

Focal length, anything to replicate something similar to the feel of the video.
Type: Prime
Budget: Low enough to go into unsafe places with about 100-150 euro

Thanks!

I've got no suggestions for an ultra-wide full-frame budget prime, unfortunately, but my Sigma 17-35mm f/2.8-4 only cost me 48 s/h from a local photographic retailer and I'm very satisfied with it

On 35mm I quite liked the Cosina 19-35. UWA was never my thing but once I had it, I was never tempted to search for something better.

There's some reviews posted for the lens with FF digital use.

Zenitar 16mm f2.8 fisheye or Tamron Adaptall-2 SP17mm f3.5.

More than anything it depends on whether you're talking about FF or APS-C. Most legacy ultra-wides are optically mediocre at best and on APS-C won't be very wide. I have a Vivitar (Tokina) 17mm f/3.5 which is nice enough but not super-sharp even stopped down. On APS-C it's not very wide, not very sharp and doesn't produce images any better than the kit 18-55mm but on FF it's more enjoyable. There are plenty of other ptions for FF and if you go with Sigma or Tamron then they might not be too expensive.

If it's APS-C then either a Sigma 10-20mm or a Tamron 10-24mm. I used to have the Sigma f/3.5 version and it was very good indeed. I understand the f/4-5.6 is not quite as good and the Tamron worse still.

I used a Sigma 10-20 on aps-c and a Samyang 20 on full frame. They are good but was never really satisfied with either. I now use a 35 or 50 on full frame and do a panorama style set, something like 5 wide by two high. For video I use a Sony fdr-ax700

As I understand the lens used in Fallen Angels was equivalent to 10mm focal length on FF.
A rectilinear lens of 10mm for FF is not easy to find, and will not be cheap.

The closets alternatives for K-mount would be Irix 11mm F4 or Venus Optics Laowa 12mm F2.8.

I can see why the style appeals to you. Kar-Wai Wong's movies are visually stunning!

Look for something in the 17-21mm range. I think the exact focal length is less important than composition and distance to subject, relation to subject and background, etc.
If you don't mind manual focus, I found the Tokina RMC 17mm good enough on my K-1; small, light and well-built.

In watching the entire video, it seems that the desired focal length is 6.8 mm rectilinear lens on 35 mm film, however the frame will be only 24 mm wide, because the film for cinematography runs vertically. So we are discussing 6.8 mm on APSC or a little over 10mm on full frame

A lens of this focal length without distortion, and for a registry distance for an SLR simply will not exist at a price you are willing to pay. Maybe something can work for a mirrorless, but….


Edit note.

I have the samyang 14mm (branded as vivitar 13mm but the same lens). It suffers from some barrel distortion, but is about as wide as you can get cheaply

You might consider a fish eye and then de-fish it in post processing. There is a 12mm full-frame fisheye lens from Rokinon for around $350US but that might be out of your price line. The nice thing is it's pretty good quality and has the standard K mount, is fast (f2.8), and is full-frame so would work with the K-1 well. I've seen some de-fished shots from this lens and they look pretty good. There's a Pentax Forum thread on doing that in the second link below.
