I’ve been using the Askar D1/D2 filters for quite a few years now and have been very happy with the results. Lately, I’ve been considering upgrading to the E1/E2 filter set, but have seen somewhat mixed reviews. If I were building a new rig, I would automatically go for the E series, but since I would be pulling out the D’s to install the E’s, I’m a little more apprehensive about pulling the trigger.

Has anyone made the upgrade and can you please share your experiences?

Thanks,

Joe

Since E’s are a narrower bandbass, you have to be careful about the F ratio of your system. At F/5.9 you should be ok.
