Railfan Technology > Have You Thought About an iPhone?

The shot of the train to Boston was taken in Charlottesville, VA, earlier this week.  The "camera" was an iPhone 14 Pro.  Using an app from Adobe, I can very the shutter, iso and white balance.  This is a lot easier than hauling my Canon DSLR around.

Perhaps it is just the dimpling thru the trees, but it looks crunchy and over processed on my monitor.

How good is the focus time with a moving train?

I don’t worry about focus in a shot like this. The nose of the locomotive is about 30’ away. The Depth of Field for this lens is 7’ to infinity. What is DOF? The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera. Wikipedia Of course you can check the focus with a look at the photo.

Your Android is just as bad. Fundamental principles of optics (physics) says smaller lens --> lower quality. No amount of sensors can make up for this. Smarter photo editing software (algorithms) can make things look good for images posted here on TO (1000 pixels wide) and the rest of the Internet, but looking at an image at its original size clearly shows the inferior details of cameras with smaller lens compared to larger lens, even if the camera with the smaller lens has higher resolution sensors.

Spy satellites that can read your license plate requires a minimum lens size (huge) in order to work properly. There's a math formula for that which I forgot, but I learned that years ago. So you won't be seeing iPhones (or Androids) in orbit anytime soon. :-)

Speaking of spying, you should also hate Androids, because they do the same thing - keeping adding addicting features (games, 5G, music, video, camera, so on) so you'll be carrying it with you (turned on) all the time. 

Not a very challenging shot, so yes, an iPhone can do a great job here. I use mine quite a bit, despite having a well equipped camera store in the back of the truck. ( There's a great quote from Ann Liebowitz that says basically that the best camera to use is the one you have with you. I agree totally. 

Amazing low light performance from iPhones as well, sometimes even better than my regular DSLR. 

But the conventional machines swamp the iPhone when things get tough:  long telephotos, zooms following the train into the frame, super high speed action, lots of others. I won't be ditching my DSLR anytime soon. 

I have to agree that cell phones usually don't make the best quality camera.  It goes back to the old photography adage that lens quality is far more important than camera quality--or, put another way, better to put superior glass on a mediocre camera body than to put mediocre glass on superior quality camera.  The big advantage of having a decent quality cell phone camera is that the user likely has it with him/her most of the time, whereas a high quality DSLR or similar camera  may be home in the camera bag when the once-in-a-lifetime photographic  moment occurs.  In cases like that, having a camera with you is better than having no camera with you.

Seems like a good photo and a good alternative to carrying a large camera.

The lenses easily shoot through a chain link fence.

From what I see not that good but gee wow about that great item you own, HO HUM shot for years with my old clunky camera. But up graded to a digital one years back still shoots great pictures isn't that bad to carry and all are full framed unlike many cell phone pictures here with a narrow picture. 

Apple iPhone 14 MAX Pro does it again - captured a surprise opportunity.  Everyone has good points.  However,the DSLR cameras and lens are getting way out of my budget's range these days.

Image size and amoiunt of usage the Apple iPhone gets more than justified the purchase.  Too many of my friednds without a cellphone always seem to have their DSLR's safely tucked away at home.  Too many lost opportunities-!

All of these were shot with my Google Pixel 6 (not even the pro model.)
