Lensbaby 5.8mm f/3.5 Circular Fisheye lens review with samples (full-frame and APS-C)

Today we have an exciting and enjoyable lens which seems to have had a somewhat quiet introduction to market. Welcome to my first ever Lensbaby lens review – although it’s not the optic they’re perhaps most famous for. Watch for full details of how this circular fisheye lens works on full-frame and APS-C cameras, and whether the quality is really any good.

If possible more lens-baby lens reviews.Especially Spark and Composure Pro.

Martin Lima says:

Please review the sigma 4.5mm f2.8 fisheye! 😀

Team APS says:

You should do a review of the new Samyang 10mm f/2.8! I’m interested in the lens, but haven’t been able to find many solid reviews of it anywhere online.

Azayles says:

What an interesting lens! I wonder, how small can the focal length be before a wide angle lens becomes a fish eye lens? Also, what’s the smallest the focal length can go? Could you have a 1mm lens for example?

Lucas Zanella says:

Chris, I think you should get yourself a blog, that way you can post the photos there and even embed the video, also write something if you like. I’m not saying to buy a domain and a server, a simple Tumblr would be nice, that way we can pixel-peep the photos you take with the lens, hahah.

Anyways, nice video!

Sky29walker says:

Very interesting lens, f/3.5 is seriously nice, despite not being all that sharp wide open.

Ben Anderson says:

“major booty”

WT about the 4.5mm sigma u dont have a video for that ?

Tomteluva says:

The downside of it not talking to the camera is that in post the software such as Lightroom will not recognize it so you have to manually check for correction profiles and apply them.
Interesting lens still and good review covering the full spectrum of how much of the circle will be shown in the different modes.

ColonelRuiz says:

Hello Chris, are you still doing a review on the tamron 28-75mm 2.8 ?

Jim Huang says:

You forgot to do the wall test for distortion. Lol

johannes914 says:

I could use that on my Canon 600d with the 2.7x “no bining” crop. It may cover the entire frame and give me a 25mm wide angle equivalent with no aliasing and moire. Do you va a 600d available to check ?

Gavin Saxton says:

Hi Chris Im a bit confused in the early part of the video you showed that you get a full circular image on the APS-C sensor but later on it seemed to be cropped top and bottom on the stills you were reviewing for quality. Do you get full frame? id like to use it for panoramic images taking just 3 images to capture the full 360 and blending these together?

Mearns says:

5.8! That’s tiny!

periurban says:

You said “booty”!

floex831 says:

Chris , please review the sweet 35 next!

Silver Whale says:

i just love your voice.

Vali F says:

As always, great review Chris! There is one thing I think is worth mentioning: I had one for a brief period of time until I realized that when focusing, the front element would unscrew, causing noticeable play. Unfortunately this caused it to sag a bit, resulting in the image circle to get cropped on my APS-C. Maybe I was unlucky and got a bad copy but were it not for this, I wouldn’t have returned it.

Ricardo Vallejos says:

Thanks man for all the hard work you put on creating these videos. You really help us all. All the best.

Iuri Ludkevitch says:

Hi Chris! Happy new year for you and your fiancée. Thank you for all your amazing videos and I hope you will succeed on great projects in 2015!

Smaakjeks K says:

This lens is just adorable! ^.^
With 5.8mm at f3.5, it should be really good for astro-photos (all things considered). Lots of light!

hollernathan says:

Nice review! Can you review the fujifilm x100t camera? I heard its one of the best for street photography! Thank you.

CK says:

Funny, a ~6mm lens with a focus ring xD. Thus I wonder the depth of field vs aperture…
