MM, quote - What about for fun? I like that.
Here is a roughly 20 mile evening view of the Santa Fe Ski Area from White Rock, just a bit of Sun breaking through the clouds.

NEX-5N + Leica APO-Extender-R 2x + 2x + 1.4x + Leitz Telyt-V 560/5.6 = 4.704m FF equivalent FOV focal length.
Image reduced in size, not cropped.

K-H.

PS: The gear

Holy smoke, K-H.! That's some seriously long stuff. The result looks like a diorama.

Fred, thanks for your comment! Yes, I did use my sturdy tripod alright. There is no way I could handhold that setup, even when I was younger, let alone now . Not only the weight but the movement at 1,600mm was ginormous. Furthermore, I venture to guess that the electronic first curtain shutter helps tremendously in minimizing the vibration from the shutter curtain at this FL. Something that DSLR users notice quite a bit ; that could contribute to the difference is IQ between DSLR and mirrorless in this case.


It's mandatory you take a picture of the full moon with this set-up now.

Here are 3 images taken of the setup using my iPad. I hope these help. Please let me know if you have any further questions. The total focal length of this is 1,120mm. I replaced the FE 2X with the FE 1.4X for the owl in flight image and the FL is 784mm. I could also remove the Canon 1.4X TC in the setup above and get a focal length of 800mm. The image quality between the two is virtually the same.

BTW, I do have a Canon 2X Mark III TC. Too bad, the AF doesn't work reliably any more.
