I noticed a new cactus flower this morning but after returning home the wind had picked up. In the past this would negate taking my camera and tripod out because nothing is standing still (I've lost control). My recent purchase of a Godox X Pro transmitter has opened up new ways to capture flowers outside even in the wind. I just use the off camera flash on a light stand, setup my tripod and go for it. The flash freezes the shot even if I'm at 1/125@f5.6 as this shot was taken. I back the flash off a bit and use a light modifier to soften the light. Was a cake walk. The only downside to it is carrying more gear. As this was next to my house it wasn't an issue. Controlling the light allows me more opportunities and I'm getting better overall color. Although you can get cheaper transmitters, get one you can grow and do more with later (you may regret getting a pocket wizard, though I have one it's limited in use compared to the X Pro).

Taken with Nikon D7500, 35mm f1.8, f5.6 @ 1/125, Godox X Pro transmitter and X1 receiver, SB-600 flash in TTL, MagMod flash diffuser, tripod and one cheap light stand.

I have been using Helicon for focus stacking with my 18-55 Nikon kit lens to photograph my very long and straight model railroad benches, 50 to 60 feet long, shot from the end. The idea is to get a sharp focus in 6-8 exposures focused every 6 - 10 feet. To see the manual focus I use the back screen highly magnified on the various points, but the kit lens, and all my lenses, change focus too rapidly with just a tiny rotation amount for precise focus at a given distance. As a result the stacked shots are not evenly spaced. Are there lenses made that focus more "slowly," that is require a much longer angular twist to vary the focus point?

Attached is an example.

A related question is how do macro photographers focus at the tiny increments required for a very small subject, like an insect? Unless a macro lens, which I do not own, should have a very slow thread for focusing.

I recently purchased a Fuji X-T30, trading in my Nikon D7100, lenses and flash. I wanted something a bit lighter for travel. The Fuji has a built-in flash but it quite low powered. I would like to purchase a more powerful flash for the occasional times I need it. Godox, a company I am not familiar with sells a couple of dedicated Fuji flashes which seem to get high ratings at B&H and Amazon. The Godox is significantly less expensive than the Fuji flashes. Does anyone have experience with the Godox flashes? Any thoughts on the two models that seem to be available: the TT350F and the TT685F?

My wife & I are taking a once-in-a-lifetime vacation to London, Paris, & Nice in September. I have a Nikon D750 with 50mm 1.4, 15-30mm 2.8, 24-70mm 2.8, & 70-200mm 2.8. We'll be walking a ton. Any recommendations on taking all of the above (& just suffer through the heavy backpack) or simplifying & lightening the load with just a couple select lenses?
I've also read a lot about taking extra precautions due to theft & pick-pockets (especially in Paris). Any advice on this from experienced travelers/photographers would be appreciated, as well.

Thank you!
