Hi Retina, Analog here.
Thanks for your appreciation for my introduction of “perspective “ into the discussions. I didn’t think I was hi jacking the point. I’ve never heard the term reach used in photography before. The original question was about an increase in focal length. I’m an old film photographer. For me, focal length and perspective is pretty much the same thing. I recently saw a photograph of the moon and Saturn in conjunction taken with a powerful telescope. The perspective of the telescopes extremely high focal length rendered Saturn and its rings in all its glory at the 10 o’clock position to the moon. Much larger than it would appear with a normal perspective lens. A wonderful example of the relationship of focal length and perspective. Hope you find this interesting. Thanks again.

I should have purchased a full frame sensor body for consistency. Thanks again.

Hi Delderby,
On review, you are correct. A crop sensor only increases the magnification and not the focal length. Same as elevating the enlarger head in a darkroom and has nothing to do with the camera or lens used. Thanks for sharing your knowledge. I think I got it now.

This is what led me to believe that the distortion in perspective is a characteristic of the lens and not the format.

Okay. I’m going to play with it some more. I’ve just purchased a crop sensor body and found that when I use a 20mm FF lens for a 30mm effective length, I get the distortion of a 20mm only cropped to 30mm. And to compare, when I use a 28mm FF lens on a FF body I get much less distortion. Why is that?

So, if I understand everyone correctly, increasing my camera to subject distance to compensate for a cropped sensor would render the same perspective as full frame for a given focal length. True?

Great series. Feels like I’m actually there.

The first example of this that comes to mind is in portrait photography. You’ve heard that the best lens for portraiture is about 85mm to 100mm. This leaves the relationship of the size of the eyes to the nose to the ears the same as the viewer remembers or expects to see in the photograph. No distortion in perspective even if the same focal length is used with a 8 x 10 view camera instead of a 135mm format camera. This is my understanding but I haven’t done this so I can’t say for sure.

Maybe what is lost in this discussion is Lens perspective. I’ve always thought that lens perspective remains the same for a given focal length even if the format changes. Please correct me if I’m wrong.

I suspect that that even today, bulb is used to eliminate shake caused by mirror, shutter and aperture movement. To accomplish this you would use a black light shield held closely in front of the lens and then removing and retuning it to make your exposure.

My son is in the Army. I do get it. I never stop worrying. I’m so proud of him. I’m thankful for your service and all who risk their lives and future so we can sleep well at night. I’m truly glad you’re okay. Thanks

Hi again. I told you how to do nothing of the sort. You’re not in combat anymore. But since you insist, I concede. You win. Hope you feel better now.

Hi ReconVic, is that better? I am friend, not foe. I complimented you work. You’re welcome. You stated you were OCD as I am. And yes, I’m in therapy. Your original post appears to be “a cry for help”. Everyone can benefit from a little help (therapy). I offered a friend (you) a little friendly advice. You rejected it. You don’t accept compliments or criticism. I’m not a analyst but it appears something more is going on here. Take my advice, if not for yourself, do it for those in your life that you love. We only have a few years left before our life flashes before us in a series of pictures. Let us both try to make them worth watching.
You’re welcome.

Hello Mr Victor.
The topic of this discussion welcomes criticism. I’m purely analog. I can’t remember when last I turned on my computer. However, I had my first b&w darkroom at 12 and color at 14 years old. I’ve been on this site for several months now just to see what digital photography entails. I signed up to comment just yesterday. I hope you feel I’m qualified to say this to you.
I feel all of your photographs are wonderful as they are. What I have a problem with is your failure to understand the difference between the two words opinion and critical. Everyone is entitled to their opinions. You however you are the only one here who is critical in the use of the word inept. That’s truly critical. I feel you owe the readers an apology. May I suggest therapy to help you understand OCD and how it affects your views of yourself and others.
Sincerely,
