p.1 #1 · Comparison images: 10mm vs. 20mm


I used the Voigtlander 10mm more than I thought I would on a recent trip to France. While at the Arc de Triomphe, I took images with the CV 10 and Sony 20G. I was on opposite sides of the Arc with each lens, but the same distance back. I thought some may be interested in the difference.





Sony 20G

  ILCE-7RM5    FE 20mm F1.8 G lens    20mm    f/4.0    1/800s    100 ISO    0.0 EV  







Voigtlander 10mm

  ILCE-7RM5    Voigtlander HELIAR-HYPER WIDE 10mm F5.6 lens    10mm    f/11.0    1/100s    100 ISO    0.0 EV

You sure make a good argument for using the 10mm! Have perspective corrections been made to this shot?

Thanks!

Yes, I used a very small vertical adjustment of -5.

The great thing about the 10mm is it gives you a much easier way of getting close up architecture right. With the 10mm, even one step back makes a big difference. I took a lot more images with it that I'll be posting in the near future.

I can't help by noticing the green fringe what almost looks like "roof" of the arch in the image taken with the CV 10mm 😜, Eric. Both are great though, different but great.

Good eye! Didn’t see it until you pointed it out. 🙂

The distortion with 10mm is quite significant, though. Those square ornaments covering the inside of the arc now look uneven and certainly not square. Given how big the place is, could you not take a better shot from outside the ring with the 20mm?

I was basically standing a few feet from the street with these shots. To get more in with the 20mm would have required going through the underground tunnel to the other side of the street. The 10mm allowed me to get not a perfect shot, but certainly a very good one with the space I had. It’s quite useful. But if you don’t want any distortion, best stick with 20mm or longer.

Shots like this is why I keep my CV10 around as well. Unique shots that oftentimes wouldn't be possible based on working distance etc. Or- an opportunity to add some creativity to one's results depending on what you're shooting.

Perfectly agree. It’s not an easy lens to use, but when you nail it, it really gives unique images. It seems many have problems using anything wider than 20mm. Compared to 20mm, looking through the viewfinder with the 10 is a whole new world. It just takes practice and lots of use.
