Doh; of course it is!  It's the scale used by Lee on their regular filters (that I own!), before they switch to using stops for their "Stopper" range.  I'm just so used to thinking of them i terms ...

There are a few scales, but ND3 for ten stops is a new one on me.  Basically though, yes - just go by the number of stops.  Each stop will double your exposure time, so if you have a 10 stop then ...

As noted, it depends on the effect you want and how much light and motion there is.  For the milky waterfall effect, you might need as little as a 0.5s exposure or several seconds depending on how ...

Interesting.  Looks like the extra pins on the RF mount are related to RF specific functionality then, rather than trying to enhance the existing mount's functionality which presumably remains on ...

So... an extension tube? :) Actually, given the extra pins on the RF mount, I suspect there must be a bit more intelligence in the EF adaptor for RF to handle any protocol conversions or put a ...

It'll never happen of course, nor would I want one, but hypothetically speaking it should be a no brainer - the native RF mount and an EF adaptor. Reason for that is pretty simple; the lenses for a ...

Aurora/astro and stormchasing.  Technically, both of those are just "big sky landscapes", but worth mentioning as the 11-24mm excels at them. Building exteriors and interiors, usually with the ...

To clarify, I was comparing the native 70-200mm (constant f/2.8) with the 100-400mm over the same range (f/4.5 at 70-200 IIRC, so close enough to 1 stop to not matter).  If you've got a 2x on the ...

For birds & wildlife I'd go with the 100-400mm, no contest.  You're very unlikely to miss the extra 30mm, won't have to fiddle with adding/removing the TC, and the TC *will* compromise your IQ at ...

Off the top of my head I can only think of 24-105mm or 28-105mm lenses with an EF mount in that range.  If you can compromise on the long end, then options are basically trying to find a used ...

I use a one of those thin bubble-wrap bags, trimmed to provide a flap to completely enclose the drone.  Achieves the same end, and is also very quick to (un)pack, but the extra bulk provides a ...

I can second this.  I still use mine, and find it to be a good lens for the price and weight, but it's not great by modern standards, and the newer 16-35mm's leave it in the dust.  It's truly ...

I wouldn't worry either.  The Mark III seems like more of an evolution of the Mark II rather than the complete redesign of the Mark II over the Mark I to me.  In the latter case, a side-by-side ...

Actually, you can kill lens fungus by depriving it of moisture (pack the lens in a LOT of silica gel in an airtight bag) or by shining a strong UV light through the lens, but both techniques can ...

Pretty sensible.  I'd generally start with seeing what restrictions a given country places on photography in general; if they don't want you photographing things with a regular camera, then the ...

I think you're possibly underestimating just how large a percentage of Canon's lens revenue comes from Pros for whom a MIL camera simply can't compare to an SLR, at least with the current MIL ...

I think we're possibly talking at cross purposes because of terminology here. There's stitching (joining multiple overlapping images to create a larger one with a greater field of view). Most...

@AlanG - having done both, there's not much practical difference between stitching an Nx1 pano or an NxN "super resolution" image, regardless of whether you have a prime or zoom lens. Ultimately...

Seems like this would be easy to test if you have access to the Zoom. Ignoring the resolution change, there should be noticeable perspective and DoF differences between an interpolated image shot...

+1, but if you want a slightly cheaper option and can do without IS the EF 17-40mm f/4 is also pretty good value for money. Andy
