Have you used the z 135mm f1.8 Plena? What do you think of it?

If you would like to post, you'll need to register. Note that if you have a BCG store account, you'll need a new, separate account here (we keep the two sites separate for security purposes).

Has anyone tried Plena for astrophotography?
Yes, does great, pretty sharp corners, colors are good, did great on imaging the comet. I would not spend the dollars to be a primary astro, would instead get the Rokinon, But if you want the Plena for everything else it does great.

Thanks for responding, Commodore. You had nice shots of Comets and Aurora lights, but I mean shooting DSOs (like the Orion nebula, etc.). Is the Plena probably not enough reach? BTW, which Rokinon lens (z) is good for Astro (DSO)? I do have z20mm f1.8 for nightscape.
 
If I remember correctly, there are a number of forum members who use the Rokinon 14mm f2.4 manual focus lens for astro milky way shots, and other wide angle dark sky photography. It's a F-mount lens that is being used with the FTZ. And is very sharp in the corners with little coma. I've never tried it but hope to acquire one.

Perhaps this lens is what was being referred to?

The rokinon 135 is the perfect lens for DSO! Many Astro folks use it. Go to Astrobin website and do a search for 135mm lenses And nebula.

Also, you will not get any DSO with a single exposure. I sent you an image from a friend, used with permission, 135mm length, mirrorless body, but tracked, with Eq mount, and stacked images. Probably 20+ 15 second images including lights and darks. A YouTube search Rokinon 135 Astro will give you hours of info.

Yes, I plan to get a star tracker.
 
Hi Guys,
Ok, not my Plena, but rather my old 135mm F2 DC lens - yeah, that one. Forgive me my trespasses, but I had to share a few shots of this wonderful lens. It is a bit soft wide-open when compared to the Plena, and doing the MF thingy on my Zf at F2 not as easy as it should be, but at least Milla was a willing model today.

No denoise, SOOC RAW, other then a bit of contrast. Always loved how these F2 DC lenses could just blow the background to smithereens.

Edit: I was trying to channel my internal @Steve , he had a gorgeous BW portrait shot of a Lion, but alas, Milla is no Lion, even though she sometimes thinks she’s a Tiger.

Here are two shots of the same flower, stopped down to f/5.6, shot with the Zf's BW, and then color, via selector switch, both SOOC RAW converted to jpeg.

Love the Plena but I wouldn't recommend it for everyone ...🦘
