Sony FE 35 Match-up: Is More, More?

Posted by

Time to trash the adapters? Sony has just released a new line of full frame FE lenses that will hopefully eliminate the need to use adapters with lenses from other systems.  We just received the  Sony FE 35mm F/1.4 ZA Distagon which has the largest aperture in the lineup and we couldn't wait to have a [...]

Announcing C-4 Precision Optics

Or, What I Did Over Winter Slow Season Those of you who read my blog regularly know I'm not a huge fan of sameness. But new lens releases, lately, have tended to have a lot of sameness. Don't get me wrong, there have been some excellent lenses released; marked improvements and refinements have taken place. [...]

Just the Lenses: The Great 200mm Shoot Out

Posted by

For those of you who haven't read our 'Just the Lenses' posts before, these take advantage of our Trioptics Imagemaster optical bench to compare lenses from different camera mounts with no camera involved.

Sensor Stack Thickness Part III: The Summary

Well, I have to admit this has been a fun series. I've learned a whole lot. That's what makes this so fun -- I get some results I don't understand, get some help figuring out what is going on, and before I know it, I've learned something that explains other things I haven't been able [...]
