Review – Lensbaby Circular Fisheye


A dedicated circular fisheye lens from Lensbaby for under $300.00 sounds great, but how does it perform?

Lensbaby Circular Fisheye 5.8mm f/3.5 Lens

Lensbaby kindly sent me their new Circular Fisheye lens (the Canon version) to review about four weeks ago, and I can tell you that I’ve had a load of fun with it since then! The Lensbaby Circular Fisheye is best used (or optimized for) APS-C sensor sized cameras. I’ve been using it on a full frame Canon 5D and actually quite like the results it gives. You can see in the photographs below that it is a full circle, you might also note the shiny outer ring in the photographs – this is because the little lens has a polished barrel. With the barrel being polished, you can mess about getting neat flare and shine into your images, but you can also avoid that by tilting the lens away from direct light and moving it around to suit.

The 5.8mm f/3.5 circular fisheye from Lensbaby is a full manual lens, it doesn’t talk to your camera, it only talks to your hand – aperture ring and focus ring are within easy reach, feels good in your hand, sturdy and solid enough. The little lens has a pop-on, pop-off plastic lens cover and a plastic mount.

The Lensbaby Circular Fisheye will focus (manually, remember everything is manual) really really close – 1/4″ close and then out to infinity.. Which means it’s hilariously perfect for when your baby decides to lick the lens – a photo series I thought about producing, but strangely nobody else wanted to lick it after baby slobber! Ah well.

With a maximum aperture of f/3.5 it’s fast enough for most situations and with an ISO bump in dimly lit rooms, I wasn’t left wanting.

The field of view is 185° which is very very wide… like, see behind you wide – well, almost!

Yes, that’s Fro Knows Photo, yes he was holding my lens… We were together for a week in Israel – more on that later!

I’m not going to talk about edge to edge sharpness or chromatic aberration, I think we’re sort of missing the point if we’re looking at those factors in a $299 lens – this lens is about making fun photographs. It’s sharp enough, it’s well built and pretty sturdy – I’ve taken it from Melbourne, to Coffs Harbour, to Israel and back and it’s performed really well. Is it worth the price tag, yes absolutely. 

Who would buy this lens?

I’d say people that enjoy exploring different types of photography would enjoy this lens, people that like making fun pictures will love it. Sure, it’s not the Canon 8-15mm L series Fisheye, but then it’s not $1500 either.

Who wouldn’t buy this lens?

People that have a spare $1500 to drop on the L series Canon (or Nikon.. sorry, not sure which Nikon fits the bill)

In closing…

My opening line “how does it perform” is kind of a silly thing to ask on a cheap lens, and lets face it, this is a cheap lens by comparison to other available options. So for the fun the lens brings and for its affordable price point, Lensbaby, I give you five of the available five stars – good stuff! (And no, you can’t have your lens back!)

    I think the worst part of the lens is the cheap lens cap they provide. Otherwise, it is a fun lens to f’ around with.

  • Lev

    More companies need to focus on delivering great lenses for affordable prices like Lens Baby. I don’t feel just because a lens cost $1,500 that it automatically signifies that it is great.

  • Federico Feroldi

    Samyang has its 8mm f3.5. Less longer, but still an interesting and cheap lens that costs almost the same.

  • Currently it is one of my favorite lenses.The distortion it creates is a work of art on its own.

  • Kathleen Mekailek

    I have been wanting to get a fisheye- think I found it!

  • Choo Chiaw Ting

    i prefer using my 35mm f/1.8g for that purpose..

  • gtvone

    Hi! With respect, they’re very different pieces of equipment.

  • +1 for getting Jared in the post!

  • Jimmy Z

    I am not getting the full ring on my exposure. Did I hook it up wrong somehow? the full photo ring is there, but the reflective outer ring is cut off on the top and the bottom.

  • Pat Scott

    Crop camera?

    “good stuff! (And no, you can’t have your lens back!)”

    That’s one statement good enough to try hands on with it!! Good write bro!!

  • gtvone

    And I still have it, and love it… Have been using it with my little Sony a7 and a Vizelex adapter – great combo!

  • AWilliamsImaging

    For $300 I’d pick up a Rokinon/Samyang/Bower 8mm fisheye before I even considered this thing, no question.

  • gtvone

    Any reason why Andy, or just because?

  • gtvone

    …and I still have it, still.

    Judging from the images in this post and others I’ve seen done with the lensbaby lens, the Rokinon/Samyang/Bower 8mm absolutely blows it out of the water in terms of image quality for the same price.

  • Phil Coxon

    Exactly what I was about to say. I have that lens, which is far more flexible, with fewer limitations.

  • Desmond Downs

    I enjoy these type of lenses – but it would still be nice to know how it performs and perhaps see some crops of the edge performance before spending money on it. After all there are cheaper adapters out there that can screw onto the front of one of my existing lenses and do the same thing so it would be nice to be able to justify the cost of paying nearly 10X more for a fully manual lens.
