given that it's difficult to impossible to focus / meter with a strong ND filter in front of the lens, aren't square filters easier to use - it seems screwing a filter on after you've metered/focused/composed is more of a pain than sliding down a square filter. plus, there are no vignetting issues.
but can someone explain to me (i'm actually asking honestly, not to be divisive) but is there a preference for screw on vs square for some reason (other than circular polarizers)? especially in a strong ND where you'll have to focus/meter without it before each shot. i understand a screw on makes sense in situations where you're not frequently taking it on/off, but don't get the preference for a strong ND being a screw on.

No question I can tell by the overall thickness for the GM 24-70. Im barely squeezing 2 slim filter rings for the hood. Reality its about 1.5 x size wise than a regular filter ring..
Fred your going to like this Loxia zoom test corners are about identical BUT on center even at F2 the Loxia is sharper than the zoom at 50mm 2.8. OH and i actually got a good 28mm F2 too. okay back to posting test.
The good news the zoom at 50 can be a very very good landscape lens if you left your Loxia home.

Really a matter of taste with the square filter holders you get a nice option for stacking and you can use different size rings for different lens sizes but of course on screw ins you can use step ups. But where it really counts is using grads because the square or rectangle filters are held in by a rail which you can push a grad up or down into the position you need. So in essence if your using grads you want square or rectangle glass and you can also use a CPL on them. So more versatile . I don't use grads myself and screw in is a more compact system to carry

thanks, i used Lee squares for grad nd previously, i guess i never considered screw in for ND (don't trust myself not to knock the lens while i'm screwing it in and figured it's too much of a pain to do constantly).

I tried those filter rings. Very clever design which I liked but it made using lens hoods impossible. If they designed lens hoods to work with the system, then I would be tempted to try it again.
If you don't use lens hoods, then it is very slick. The cost adds up buying all the rings, but once you have adapted all of your lenses and filters you are set to go. If you don't use a hood and need to swap filters often, it is a great system. They were fun to use also. The filter attachment with he magnetic rings was solid.
I just got as far as testing out the fit and ergonomics before sending them back to B&H. I did not test for vignetting.
If I recall, using the lens cap was an issue too. For the money, they should offer plastic lens hoods and caps.

Back to test. No real surprise here but this is a better copy of the 28mm which will reside on the A6300
Since i did the wall test with the Zoom I since acquired two lenses the Sony 28mm F2 and I bought back a Loxia 50mm F2. So i need to test them anyway so i thought it would be nice to see them at mid zone along with the zoom.
Serious amount of distortion for the 28mm. These are Processed in C1
Okay lets get to the left corner test out of the gate no need to post F2 on the Sony, trust me you don't want to see it anyway.

Enough with all this boring lens talk........I'm waiting to hear about this Tenba Cooper 13 Slim, how the hell are you shoehorning all this kit into it, has that A6300 slotted into it?
I spend far more time on the "ideal stealthy bag search" than I do with hardware. ~Chris

ROTFLMAO. I might have to get the regular DSLR now.
Its getting tight in the slim. The zoom is a truck lets be honest but Im trying to carry everything right now and i won't be doing that for real either. i do have a Gura Gear 18 backpack which I love also.

Moving on to the Loxia 50mm and the GM zoom at 50 things even up in the corners so lets check that out. i think you all know the full wall by now so i will skip that lets get to the upper left crops . Again no asymmetry issues on either lens and both very good copies of each..
So the zoom gets the corners faster but obviously the Loxia 50 catches up. So very good for the zoom but this does change on center

i'm about to report on an alternative to the Tenba Cooper 13 slim (which i love) - it should arrive this week: it's bigger but not by much and has some really interesting looking features: Peak Design Everyday Messenger. https://www.peakdesign.com/product/bags/the-everyday-messenger/
the biggest feature i'm looking fwd to checking out is the magnetic clasp system with 4 positions to allow the bag to be as small/big as you need it to be.
My Tenba Cooper 13s was perfect until i replaced the batis 85 with the 85 gm - the casualty was that i'm no longer able to also include my nissin di700a flash, but in the TC13s i can fit the following in the main compartment:
batis 18 (room set aside for it's arrival first week of May)
batis 25, zony 35/1.4, zony 55/1.8, sony 85 gm
sony a7r2
i've been wondering myself how Guy can fit both the 24-70GM, 85GM, a7r2 into the tenba C13s and fit anything else - i'd love to see a photo of what's going on with the bag today Guy !
i may just stick with the TC13s however (if the PD is too big, which it seems like it might be for me). i can live w/o taking the flash everywhere with me in exchange for a really tight package.

Guy - are those crops from the 28mm lens with or without the distortion correction applied?
I always wonder how much corner sharpness if affected by distortion correction on lenses that have more than a fair amount of distortion.
