Would I be able to get this shot with a 15mm or 21mm?

Excuse my ignorance, but I only have access to the kit lens which goes to 18mm, so I'm hoping that some of you would be able to help me decide. I'm leaning towards the DA 15 ltd for versatility, but photographs of this nature are important to me.



Thanks!

Either lens could potentially take this shot, it is just that you would be closer to the subject with the 15mm. Since there isn't any exif information with that image it is impossible to tell the focal length of the lens used or aperture/shutter speed etc.

This photo appears to have used a longer focal lenght in the 30mm range.

15mm (and wide angles in general) are undesirable for portraits because they distort face proportions... in particular making noses and ears stick out.

15mm is a horrible portrait focal length

I'm also thinking more like 21mm, but the primes are very different then your kitlens.

I have no idea who took this picture, or what it was taken with. I might have been a point and shoot!

The distortion of the background and of Thom's height led me to believe this was shot wider than 35mm, but I'm asking you folks for a reason .

At 15mm the lens would be close to the subject to take a picture like that. 15mm is a lot wider than 18mm, you can get your own feet in the frame with 15mm if you wish.

I really like using the DA15. It can take interesting photographs of people, but it is a little trickier to get realistic looking portrait type photos because of the perspective.

Definitely a 15mm would be a bad choice. A 21mm or longer would do. I agree that this shot is with a wider lens than 35mm.

Both would be appropriate, this was done with a wide angle focal length...look at the edges of the photo; on an aps-c sensor the 15 would be similar to a 21 on 35mm sensor and the 21 would be close to a 35 on a 35mm sensor, that said the 21 would be a better allround daily use lens for an aps-c sensor.

Yes I suppose I should clarify "what focal lengh for a 1.5 crop sensor ).

So it seems this IS 35mm.. if it was shot on film. For digital then, my best bet would be the DA 21 or FA 20 / 24 for a non-zoom option.

For a full-body shot with surrounding context, 15mm is fine. Otherwise, I don't get too near someone with a lens shorter than 24mm. And even 24 is pushing it. A good reason to own a 28mm lens is that it's the shortest FL that's safe for head shots. And 35mm is even better, giving a similar AoV as 50mm on FF. Aha! THAT is why Nifty Fifty's dominated the film era -- because they're good for portraiture over a range of distances.

Anyway, this picture was likely shot with a 35 on film; the APS-C equivalent would be 24mm.

You can get within inches of a person with the da21. It just depends on your angle and their features.

Yes. but the DA15 and DA21 are better with distortion control. I would assume you took this around 18 or something less than 24mm, judging by the amount of background distortion.

Like I said, this was not taken by me. It is likely not even a pentax camera... or potentially not even an SLR! However I like the "drama" of the photo and wanted some opinions on the FL I would need to take a photo like this. So you think I would find this closer to 15mm than 21mm.... disregarding the distortion?

It's definitely a wide angle of some sort...look at the distortion of the door frame on the left side of the pic. I'm thinking it's somewhere in the 20mm range. Also, be aware that some of the drama that you're getting from the pic is artificially induced. Look at the halo around the head of the subject. The background has been darkened quite a bit.

Thank you for the FL input, and good eye on the halo! That is certainly part of it - but I do think the perspective distortion adds to the dramatic aspect of the picture. If this was a compressed portrait, it might be more flattering, but it would be less interesting (to me, anyways ).
