[f/2] Used with a Celestron 1250mm scope. Can easily see craters on the moon clearly.

[f/2] Tele Vue eyepieces are among the best available for hobbyist. The design, materials and workmanship are superb. Yes, they cost a few bucks more than other makes, but the buyer is rewarded with clear sharp images and a better experience.


The 6mm Delos is a terrific eyepiece. If you are transitioning from beginner to more advanced user, this eyepiece makes a nice addition to your kit.


Beware---it's a slippery slope. Once you buy in to Tele Vue eyepieces there is no going back to lesser makes.


Clear Skies.

[C] I love this lens! The build quality is top notch, and the focusing is really smooth. I've been using it for astrophotography, and some interior architecture shots, and am delighted with the results. With a lens this wide, I can take night time exposures up to 40 seconds long before having to worry about star trails. Very sharp and the minimum focusing distance is amazing also. Highly recommended!

[Manual] I have the Laowa 10mm which is quite sharp and comes close to the claimed zero distortion, so I was curious about the 6mm. I was skeptical of the YouTube reviews where the guy raves it's sharp as a saber! Only one review, Photoblograper, said the lens was soft in the corners, which would not be suprising for a 6mm.

So...is it sharper than a ninja sword or mush in the corners? To my amazement, it's pretty sharp wide open, totally usable even in the exteme corners--IF--you don't mind the expected loss of corner illumination, aka vignetting. Optimal sharpness seems to be around f/2.8 but for even illumination in the corners, I'd use f/4 or smaller. I happen to like darker corners and often darken them in Lightroom, but that's what I was taught in the Ansel Adams books so maybe that's no longer in fashion.

I need to repeat the test, but it seems image quality dips after f/4, then returns at f/8. Unusual. Zero distorton? No, but pretty close. If you're aware of the incredibly high barrel distortion in most digital camera ultra-wide lenses, you'll realize how impressive it is to get close to zero at 6mm (equivalent to 12mm on full frame).

In short (no pun intended) here's another reason to like m43. A tiny, reasonably priced ultra-wide. Even if you don't use it every day, it won't be a hassle to have with you, just in case.
