Wide Angles, 10mm or less?

Post by titrisol » Fri Jul 24, 2020 8:49 am

How wide have you gone? At a certain point I had a 15mm lens and a 17mm Fisheye (still have)
But with the 1.5 factor because of the APS-C camera those are not that dramatic anymore.

I got some (kinda unexpected) extra income from a job I did in 2018 and bought a Sigma 10-20/3.5 from KEH
My camera is APS-C format (PENTAX) so at 10 it should be equivalent to a 14mm in 35mm
The lens arrived a couple of days ago and I just took it around the neighborhood.
- Lens is heaaavy!
- AF works well,
- Pictures are sharp enough even though not super sharp
- Angle of view is quite dramatic, distortion is not bad
- Purple CA is noticeable, towards the edge
- I had a graduated ND filter from Cokin and allowed to get decent sky colors

All in all, I guess it more me that needs to learn how to use this lens better

PS, just for fun I put the lens in an old ME Super...
Not bad!!! vignetting at 10mm, gone at 14mm

I had that lens a while back, but wound up selling it because I found only limited use for that wide a lens. Below is a sample shot with a not-yet old Pentax K100D (6MP as I remember).

Widest I have used is 18 mm in a zoom, and 21 mm in fixed lens. Good for dramatic perspectives, line composition and if you get splendid skies.

I remember people using ultrawides in meetings, Al Kaplan was a fan of 15 mm.

For almost five years, I have had an 8mm Olympus lens for my OM-D. I do use it now and again (just to remember what it's like!), but it's a sort of one-trick pony and I have not really figured out what to with that one trick.

The Sigma f3.5 10-20mm is plain lousy at 10mm, but sharpens up from 12mm onwards if closed down to f5.6 or f8. Chromatic aberration is also bad at any focal length. https://bit.ly/2WS55Ph
I bought a pre-loved Nikkor 10-24mm f3.5-4.5 G ED for my Nikon D7100, which is APS-C, and I am very happy with it. This is taken at 11mm:

This at 15mm

I had the Voigtlander 15mm (I think that was the focal length), but apparently I sold it. I haven't seen it in years, so I guess I sold it.

I have the Zeiss Ikon Contarex Hologon, which has a no-focus fixed-aperture f/8 15mm Hologon lens. I think depth of field is 18 inches to infinity. It's a pretty cool lens, although its uses are definitely limited.

This was shot on Kodak Gold 400 - way too much grain.

I've been looking at some of the Irix lenses. They are affordable.

The widest I've gone is 144mm on 10x12":

This was a Scientific Lens Company 8x10 Wide Angle. Have no idea what the 135 equivalent would be. Funny thing was it was a tiny little lens, especially mounted on the 10x12:
