You also might want to play with the different perspectives you can get with telephoto and wide angles. 50mm is about the classic portraiture length (75mm equivalent) but what about more dynamic shots, or group shots.

Just a thought, you didn't have the 'Toy Camera' mode on by mistake?

The performance of the 31mm on FF is no surprise, but the DA70 shots are also pretty good. It's nice to see it performs pretty well on FF when you move away from the 'brick wall test' and shoot some actual pictures. A little bit of vignetting and softness at the edges (and there isn't actually that much of either of these!) is no problem when you are shooting people against OOF backgrounds....

A 100% view of a 24MP image will show a 'deeper' crop of the image than a 16MP one, magnifying lens aberrations and perhaps minute amounts of camera shake etc a bit more. But this is only significant when pixel peeping, not viewing a normal image sized for web or print. To get around this you could A) use finer quality lenses and refine your technique, or B) stop pixel peeping all the damned time and take some real pictures.

Algi, go back to the original post which is about crop sensors vs full frame. The point is if you crop a 16mm lens to give the same angle of view as a 24mm lens, as happens on a crop sensor camera, the results will give exactly the same perspective. Numerous examples posted in this thread prove this beyond doubt!

You have dismissed these examples saying that the 'magnification' of the image is misleading, but it is the magnification of the image - or in other words the 'crop factor' - which is the whole point of the discussion.

Presumably the little placards under the pictures here contain instructions as to where to stand when viewing the picture....

If I didn't know better, Algi, I'd assume you're confusing the topic with a side-issue to distract from the fact that you're mistaken

Algi, your increasingly desperate statements defending your demonstrably incorrect position are very entertaining - thanks!

Think you missed your true calling as a theologian

'You should position your eye closer when viewing WA shots'

No.... sorry, no - I mean, who does that?!

Had heard about this on the news briefly but not probed deeper into the story until now.

Dear god... I feel sick

Looking forward to Algi's rebuttal!

The 18-55 is pretty bad in my experience, smeared looking and cyan fringed towards the edges even stopped down. No such issues with my DA16-45 or Tamron 17-50mm. Maybe people have had better luck with their samples, but I find myself in agreement with the reviewers - the K3 deserves a better lens!
