p.1 #1 · Irix 15mm f2.4 Firefly or Blackstone?


I have a big dilemma...

Right now Firefly costs $399 and Blackstone is $599. Optics are the same.

Is it worth spending 50% more $ for metal housing, engraved markings, reflective paint, 4 gaskets instead of 3 (front element is not weather sealed), a black box, a better case (which nobody uses it), a nicer feel?

And just so you know, I'm not the type of person jumping over a cliff while shooting a crocodile nor willing to shoot in the Amazon on a crazy storm.

What would you pick and why?

Thanks!

I have the Blackstone but not tried the firefly for comparison.

I also had it provided by irix so didn't buy it

I bought a used Firefly from my friend, so far so good. But per my friend told me he just tried 2 to 3 in the shop and found one have a very big dust inside the lens and one have symmetric focal plane issue and he was lucky to find the third one was acceptable. I haven't heard the Blackstone have these kind of issue so far.

I mostly use it for astro as I dont have 95mm filters so find it harder in general to use for landscapes vs my 16-35.

Its sharp for landscapes and the distortion is good, flare isnt the best though (compared to 16-35/4).

Heres my latest astro with the 15

I'm wondering if other people experienced the same issues...

That's a beautiful shot, Rob!

I already placed an order for a filter holder and ring (from a weird company in Korea) so I can use my Haida filters with this lens.

What I'm still debating is if I should pay 50% more for Blackstone...
Which version do you have?

I have the Firefly version of the 11mm F4.0 on back order. Don't see any reason to pay anything more for bells and whistles on a 3rd party lens that I would use infrequently. Actually plan to team it with my Nikkor 14-24 F2.8 for a faster/cheaper combo to sub for a 11-24 F4.0 Canon.

Once you get it, can you please share your thoughts about it?

Anyone able to do a comparison for night shots only with the Samyang 14mm 2.8 (not the new 2.4) ?
Say sharpness, distorsion and coma
