Thanks - this one is definitely earning its keep. Used it on another job this afternoon. I've a few more 'mods' to consider.

Nice! Looks more solid than my previous attempts at a diy rig.

@@KeithCooper OK Keith. I'll try and make this as easy as possible. I have Macro Lenses (100mm Canon L IS and Sony IS 90mm). I have crop and FF Canons. I have FF Sony. I want to do some greater than 1:1 but as you can see I have different options. I'm looking at the Laowa 100mm or to use what I have. But not sure to go Canon or Sony. One big thing I've noticed I do now with the Sony set up is going for shots I'd not try with the Canon because I'm on really extended tripod and I think the lens' IS is helping a lot. One avenue tho is use what I have. The thing I tried today was 5D II with 36mm ext tube and 100mm IS L. My non flash shots all seemed a bit soft and I noticed CA. Flash lit were better for sharpness. Looking at Live View with IS on, the view was drifting around. With IS off the LiveView was solid (faulty or this is what they do?). So IS negates any easy stacking. Also fixed ext tube was limiting. Maybe lens not ideal for 36mm tube? Contra to most I'm wanting to do available light shots not strobe macro, so softness and not having good IS is limiting. If I go the Sony route I may be fudged there as my body tells me IBIS is not available with the Sony Macro ( ;/ ). But I think there will be less kinetic energy with the Sony shutter than the Canon. Next is I'm thinking of upgrading. A 60MP Sony or used 5D SR. But can the Canon be triggered to leave about 10 seconds between mirror up and taking? I can't find the duration available in the menu. So that's about the size of it! So do you know a work around with the 5D SR to absolutely stop vibrations? Do you think the Sony route would be better? I cautiously tried the ext tube I had but reading whats on the market (to go the Canon route with what I have) seems there are too many reports of poor quality tubes, some loose fits and some damaging cameras) which also puts me off extending my ext tube range. So faff with what I have with mirror slap and one tube. Maybe 5D SR would obviate this? Maybe higher model Sony would have IBIS that works for EOS mount (I have MC-11 adapter) or maybe the straight Sony E would have working IBIS with higher level Sony body. But I like the idea of manual F stops and thats only with one version of EOS. Because I think I'd rather have manually actuated f ring to save battery (my Sony actually shuts down the aperture as its selected and not just for the taking) which I think uses batteries - like I changed three a day. Not straight forward from my perspective? I think getting the Laowa lens itself over 100mm + ext tube would be a step in the right direction? But for what body I don't know. Me 🤓 Keith Cooper 🤦‍♂why me?

@@killpop8255 That's a lot in a 'comment'... :-) 36mm is a tube I'd rarely use - I have a set of smaller ones Can't comment on anything Sony - I'm not on their Christmas card list, so have never had a chance to test any of their gear at all. To completely get rid of mirror shake I do my stacking from live-view on my 5Ds I've also never used any form of IS with macro... This is something to ask somewhere like the Macro forum at DPReview ;-)

There is no 'buy these' list I'm afraid - the key idea is the hinged flap to mount things on [with 1/4" bolts] The motorised rail is a long carriage Stackshot rail The quick adjustment rail is a manfrotto 454 The blue scissor style up down support is from Temu - cost me £2, but seems to have gone back to £18 The grey slide and tripod heads is from a Rogeti kit rogeti.com/products/rogeti-accessories-kit There are lots of different ways of doing this - I just used what I'd got around. I see quite a few types of slide rails on eBay and you don't need a motorised rail I'll probably use the board in another few videos and be sure to include more details

Inchs? An 8mm or thicker bolt should be able to control the rise and fall of your table. Similar for sideways movement. A few years ago, I tried a 90mm macro lens plus extension tubes outside. The weight of me moving near the tripod was enough to cause camera movement, Many years ago, I lived in Burwood Hwy, Burwood East, Victoria. The middle of the highway was a tram route, and whenever a tram went by, the house vibrated. I don't know what that did for house longevity, but I was glad the club darkroom was far away.

Yes - I still think in inches and feet and calculate/measure/cut in millimetres... Equally comfortable with either, and inches help my US viewers ;-) A bolt will do nothing without things around it... I don't have a workshop. The only bolts in this are 1/4" 20TPI ones through the board to anchor the stackshot - they may even be 1/4" Whitworth [from one of my assorted nuts n' bolt boxes. The stuff here is used because it's what I had - the key element of the design is the hinged board.

I remember reading on the topic of vibrations in darkrooms, people in hi rises in IIRC New York could see the water in their toilets move courtesy of the building swaying.

Have you ever tried wide angle macro? I've been trying to do some macro and near-macro and the extreme background blur, thin dof and flat perspective of normal / long macro lenses often make it challenging to get an interesting composition.
