Re: Sony A7R with microscope lens

About Nikon F to Sony E adapters, it is unfortunately true that most of the cheap ones from China are so-so in mechanical quality. For my Sony FE cameras, I try to use Metabones Nikon F to Sony E adapters, in part because the front and rear bayonets are better than average, and in part because the s...

Re: Would you recommend a tripod or monopod for macro in the field?

I try to avoid using either tripod or monopod as much as possible in the field. My favorite technique (which is nothing novel) is setting magnification with the focusing ring, stop down if necessary, then start at a distance slightly too far from the subject, move gradually toward the subject and tr...

Re: Diffusing a Macro Twin Flash

[...] Stupid idea I had how was about a bit of foil on the centre of the puffer plus to reflect the hotspot back into the diffuser so it reflects back around and back out? Maybe cost too much light though. [...] Something similar is actually done in some speedlight diffusers, which are made of a si...

Re: Diffusing a Macro Twin Flash

[...] The dimpled plastic type of diffuser looks interesting. There are products that have a similar texture. One that comes to mind right away are the very cheap translucent plastic panels for fluorescent ceiling lights. These have a diamond shaped dimpling pattern rather than circular one, but I ...

Re: Olympus is leaving the camera business

It may not feel good, but on the other hand, this does not mean the end of Olympus cameras and lenses, but just a rebranding and/or a new management. JIP are in the business of purchasing industrial assets, restructuring them to make them profitable, and then selling them on. I don't think JIP will ...

Re: What could be the cause of this?

My interpretation is slightly different (unless I skipped too many earlier posts). It is based on the assumption that this camera has no hardware anti-aliasing filter, and therefore that it is implementing anti-aliasing in software (if this is not the case, then you don't need to read the rest of th...

... If we had just kept the schools open, we'd already be there. Let the virus spread in the schools, then the kids bring it home, and voila, herd immunity (at least to the prevalent strain) in no time. Sweden did not close its schools. Yet it is estimated that the percentage of population positive...
