LOL; I was in the same boat until about age 30, since then I have always had a mustache, full beard about half the time.

The longest 35mm camera focal length I can reliably handhold at 1/60 is 50mm. A tele lens with image stabilizer helps, but typically (for me) only one out of five or six exposures is usable when relying on the stabilizer.
My recent attempts to shoot the ISS with a 500mm Sigma zoom have failed miserably. Wish I had known about the Nikon P900 (thanx, alf85 -!) - I should have spent the Sigma money on one of those.

I just got a Yongnuo 2x tele-extender to use with the Sigma 150-500; preliminary tests show the extender gets me a sharper Lunar image handheld, 1000mm, f13 ISO-800 1/320, than trying to make an ISO 200 (Canon 5D-II) blowup from 500mm. I'm trying again tonight, 4-30-2018. Reason for the high ISO is the tele-extender gives me a maximum aperture of f13 or f20 (EXIF data, it seems accurate to me), and I was hand-holding the camera. The original was color, light blue sky; I darkened it as much as possible to increase the contrast.

The co-pilot's wheel is a mirror image of the pilot's. Shouldn't they be identical?

Compare to $77 for factory cleaning with Canon, with shipping both ways. But that was for only one camera; I'm sure the Belkin kit is good for a number of cleanings.

I have a 5D (mark I) for backup. Plus, no shops within 150 miles that I'd trust.

Return to factory for cleaning. I shipped my Canon 5D-II, USPS to factory was $11, included full-price insurance. Canon charged me $66 for the cleaning & shipping back to me. Time at Canon was one day, I had it back in 9 days.

One second is too short. You lose half your audience because comprehension shows down with age, and flashing the pictures too quickly doesn't give them time to be actually seen. Today's TV commercials in particular annoy the H out of me when they flick by before I have a chance to appreciate whatever visual appeal they may have.

I found the most useful range for my landscape purposes was met with the - pardon the intrusion, I am a Canon user - 28-105 II USM. True, it has a bit of vignetting at 28mm, but my 24-70 f4 L IS USM, nearly vignette-free, is too wanting in the telephoto department. Another reason for preferring the less posh 28-105 is that it is lighter and more compact, easier to use in my style of shooting; just a thought; I'm sure others will put up with heavy and bulky for the better edge quality, but the center sharpness of the 'cheap spread' is just as good as the 'L' Canon lens. I'm sure Nikon has similar quality vs. portability issues.
