Do you think that you may be expecting too much from the masters that frequent this site? There are REAL photography forums like Fred Miranda, fstoppers, etc. that you can find the criticism you're looking for and by all means more that birding and travel scenic photography.

Who needs more light control?

Smacks of Mick Jagger with different gear.

I'd suggest 0 mph. Yep, stop and get the arf off your arse and breathe some fresh air, stretch it out a bit or NOT and miss being there.

"Just sayin'...". WTF, are you the ad cop here or just a schnorr yourself?

Hmmmm.

When asked by his mother, "Johnny, why are you in the horse stall? You're covered with manure." Johnny replied, "Mom, I know there's a pony in here somewhere and I think he took my D850".

Personally, I feel that the vignette ruins the image.

Just to mention the specifics in this ramble, almost all lenses shoot best at f/8; okay f/5.6-f11. Outside of that one needs to shoot at a shutter speed that will be fast enough given the focal length and your steadiness. Now, for the least noise shoot the lowest ISO and in RAW ETTR. I calibrate every lens in my arsenal by adjusting back or forward focus with the center point prior to shooting and all this pays. Aint nuttin' wrong with your gear even though there's better, it's knowing how to use that makes the biggest difference. Pardon me, but do you know the way to Carnegie Hall?

As seen in the shots above that were not metered correctly, the whites are gray, but that's not how the photographer saw it. It is how the camera saw it at 18% gray, so shoot manual after you determine how much to overexpose, like somewhere around 2 full stops or aperture priority with a similar +. It's basic knowledge since back in the day of film, but these days o' digi we have no excuse; there's instant review on the LCD. Shoot RAW ETTR. School up before and you'll be happier with the results later.

The best camera to use for any photography is the one you own and using it will only improve your ability.

All gear is available

Beat a dead horse with very little really usable information, but that's UHH for ya.

Have you ever heard of lens flare?

All equipment is still available. PM with your interest in one or all. Thanks.
