The Sony A7R IV price dropped to 2298 with EDU discount today, in case anyone else is interested in a new camera. They are updating some a7r's models with a higher res lcd, and are pushing big discounts on the old stock

FIne! It's a well worn path - which will take you and your wife to the north. North of $10k, in a jiffy. Thanks Bitcoin! :D I just noticed that Levon Biss has done some work on amber specimens! I'm blown away https://levonbiss.com/projects/amber-series/thumbnails See for example his https://levonbi...

I'll just repeat myself, GET MORE PIXELS, you will never regret it and you will still outresolve the sensor with good lenses. See Beatsy's recent tests. If those don't make you want to get an A7R4, I will be surprised. http://www.photomacrography.net/forum/viewtopic.php?p=272808#p272808 I've been l...

Thank you for the info and recommendations! I can see how our setups would be similar - I believe the refractive index of Amber is around 1.54 so glycerol would be a decent immersion media if I went that route. Immersion lenses seem pretty expensive, but would probably give the best results. I also ...

First of all, thanks to this community - I've learned a lot in reading forum posts over the past few days. I'm looking to create a macro photography setup to acquire images of small fossilized insect inclusions in amber pieces, along with other small plant, mineral, and insect samples (budgeting aro...
