A lovely portrait of this charming fellow Javier! I see on flickr that this was with the Nikon BD Plan 20X 0.40 (is it the ELWD?).

A starting point in DIY thinking can be a dividing plate as used with small lathes Have a look at examples here:http://www.rdgtools.co.uk/acatalog/Dividing_Head_Accessories.html Thanks Len! This type of construction might even allow for variable step sizes. I can see how this could be useful if you...

I'm really happy using a linear stage for my field stacks. Of all the macro rails I've tried nothing even comes close to the precision of the linear stage and it cost me less than $50 (eBay). The one I use is 2" travel but I don't think I've ever used it outside the mid 1" section so it could just a...

Yes, the these are beautiful Nikola! Like I mentioned in the chat I don't think you can expect much more resolution considering the NA. Possibly there is some still some room for improvement on the CA and edge definition departments – a different tube lens may do the trick! These are uncropped with ...

instead of vignetting it behaves similar to a regular lens aperture Very interesting! Perhaps I need to rethink mounting this lens the way I do since i makes it impossible to change aperture without removing it from the bellows. BTW, I was surprised to find a quite noticeable performance improvemen...

Thank you very much! What kind of Exposure times are you getting lets say with your mitutoyo 10 apo? It's in the 1/25-1/10 second range. I hope you enjoy my admittedly humorous report. Definitely :lol: And I agree, the bug abstinence is not easy to deal with this time of year. I'm lucky Nikola took ...

I too prefer the second one and mostly for the same reason (lighting). If I had to pick a favorite purely based on detail rendition it would be the second one as well – from what I can see the first one appear a little softer.

Thank you Tomas and Javier!

Forgot to mention that the first one is with flash (one Nikon SB-24) + MLU and 1/200s and ISO 100, and the second one is with 2x Jansjö, EFCS, 1/20s, ISO200.

Yes, monitor differences can make a huge impact and the laptop screen I'm using right now is not hardware calibrated in a couple of months so it may not be the best reference. I find that the WB is often highly dependent on the background – with a green background like in this case you will often ge...

I'm following this thread with great interest! I've probably seen those "optimum sampling" figures some time before but it was very interesting seeing them again. Horst, if you can show us a sample image from the Mitutoyo tube lens at some point it would be greatly appreciated! Preferably one showin...

Cychrus caraboides, Carabidae These ground beetles feed to a large degree on slugs and snails. Their mouthparts are highly specialized for this purpose! This specimen was in pretty bad shape, missing most legs, palps and one antenna so this is more of an artistic study than an entomological one. Al...

Very nice portrait! The detail and stacking looks very good. This is with shot with your automatic setup? I think it can improve with some simple post processing adjustments. Some of the bright areas on the face seem slightly overexposed but it's probably not beyond repair. There also seems to be a ...

how do you compare your zeiss 63 to the mititoyo as far as image quality...(not mag) Tricky comparison to make. The Luminar 63/4.5 I have (first version) shows some purple fringing around OOF highlights. The Mitutoyo doesn't. My Luminar also has a distinctly warm color rendition whereas the Mitutoy...

I used flash for these but the last couple of days I've been using the Jansjö lights for exposure with EFCS – works very well and the results are similar but more predictable.
