@wcfn100 Is that the insanely expensive brass K27 that was made a a few years back ? I thought about getting one , but the price scared me .
Bob, I'm surprised you like that perspective. I never like how wide angle lenses stretch everything out. There's also going to be some issues as you get into scenic areas. Even in your photo you can see the signal bridge is distorted and the back of that F3 is out of whack.Jason

I'm just the opposite - to me the exaggerated perspective when using wide angle lenses makes the tiny model train look more like 1:1 scale train photo taken with a normal lens. Human brains seems to associate a strong indication of a vanishing point perspective with large size of the object in the field of vision and/or with great distance. That strong vanishing-point perspective is often missing from model photographs. So they look like models. Well, it you want a photo of a model to look like a model then a wide-angle lens is not the way to go. But since in our modeling we usually strive to achieve verisimilitude to the 1:1 scale world, using wide angle lens helps to achieve that. We go crazy making the models as detailed as possible and the scenery as realistic as possible but then when we photograph it, that realism is lost with flat perspective.
You could say that he crossed the boundary from reality to art. He does that sometimes.
Well, ok. But here's what happened in the above photo. Bob's combination of lens and camera resulted in a horizontal angle of view (this is what the camera captured) of about 140 degrees. The average human eye has almost the same angle of view. The difference is that, for most people, only the center 50 degrees or so appears to be sharp. The other 90 degrees is what we call our peripheral vision. Bob's photo is a panorama, and, strictly speaking, does not represent what the human eye would see. You could say that he crossed the boundary from reality to art. He does that sometimes.
I can't explain this one. If you look at the "before" version of this photo, the distortion you mentioned is much, much less. Maybe he PhotoShopped this image one too many times.
Just to be clear on this, Peter, if your camera is set up to take a photo that has 140 degrees of view, then the image, whether it is a 1:1 subject or a model subject, will capture a field of view of 140 degrees. Some people like that effect, some don't. It's a matter of personal preference. To my eye, the most pleasing perspective results when the field of view is about 55 degrees. (This is what you get when you use a 35mm lens on a full frame camera). But that's just me.
I'm not trying to be negative with any of these comments, just trying to make us all think about what we are trying to achieve.
The other main goal was also to see if the lens would generate a view that created "perspective lines" which are quite evident in many prototype railroad photos, because photographers, when confronted with huge objects, often use wide-angle lenses to capture those objects, rather than just pieces of them.
And that's the crux of it I guess. My frame of reference and what I hope to duplicate in my model photos are the Joe Blow shots like I posted in the Thursday Proto Pic thread. That's just my dad with his Nikon. If you had something big to shot, you either backed up or found an angle.Jason
Which is no problem and makes for a neat shot. It was just his remark about this lens taking the place of using focus stacking. I don't think this lens is a substitute for what focus stacking can achieve. But if someone can make it work, it would be Bob, so maybe he'll show us some other shots.I'm in the camp of trying to duplicate the old photos I have that were typically shot with a 35mm film camera and 50mm lens. I can try and mimic it by adjusting for Nikon's DX crop factor and shoot with a 34mm focal point. My issue right now is focus stacking can flatten out an image because as you move the focal point back, those parts get adjusted in the frame. I'd like to find a balance of maintaining a realistic perspective but avoiding the fish-eye. Not sure if that can happen without some sort of post process which I'm fine with because I may be able to just write a script for it in PS.Jason
