Real-Life Ultimate Fisheye Comparison (Rokinon 7.5mm vs. Olympus 9mm BCL)

One shouldn't get too nerdy about lenses. Just enjoy the eye of the fish and what it delivers:

Forgot to mention, this was taken with the Olympus 8mm eye of fish.

 

Thanks for the comparo. I can never tell much from a 1500 pixel image, but the crops tell the tale.

I pre-ordered the 15 mm BCL and was bummed out by it so had no interest in the fisheye BCL, especially since I already had the Samsung fisheye. I think the 9 mm BCL is still going to be a fun lens for most users, but its price should be a lot lower, maybe $69, since it's not intended as a serious lens.

 

Awesome comparison, especially the crops -- thanks much for doing this. I really like the idea of a lens I can pocket for those light-weight excursions, and as OzRay and others have shown, there's a lot of fun to be had with it. I'll probably wait for a sale or a reconditioned, though, both because I'm a cheap bastard and already have the wonderful Rokinon.

 

Thanks for posting your comparison! I own both lenses but haven't taken the time to do so myself.

One thing to consider, the BCL suffers from quite a bit of lateral CA and turning on CA correction in LR will improve the edges quite a bit. They look even worse in your comparison because of no CA correction. Of course a comparison with no CA correction is completely valid on its own - its what someone shooting JPEGs is going to get. But I did notice things were markedly better with the BCL edges when applying automated CA correction in Lightroom.

Personally I'm quite happy with the BCL. It goes places with me and the Rok doesn't most of the time. For me the BCL is a targeted output of 5x7 at the largest in a book or 1024 on the long dimension on the web. It is plenty sharp for those targets, especially since in almost all my compositions with this lens the edges and corners aren't the focus of the image to begin with. In those cases in which I would be concerned with such things I'm on a dedicated photo outing and would have the Rok or the 7-14 with me instead.

Definitely a niche product...

Again, thanks for the nice comparison photos - should be very helpful in setting people's expectations appropriately.

 

Thanks, I've been waiting for someone to do this!

I have both the Rokinon and the 15mm BCL - $235 for the pair. But I still think it'd be nice to have the 9mm BCL fish eye thrown in my bag to be used as a body cap and a quick, portable switch to wide angle in a pitch, crappy quality or not. So, if anyone has one they want to unload cheap, PM me!

 

Those samples pretty much say it all. I guess Pentax has their Toy lenses and we have our Body Cap Lenses.

 

This week end I tried to get the BCL 9 mm... quite hard to find in Europe.
I want this lens from the beginning, since I read this test from Robin Wong:
http://robinwong.blogspot.fr/2014/02/olympus-9mm-fisheye-body-cap-lens-review.html
It's small, it's not too expensive (a little overpriced maybe at 100€), and as it is only a 9 mm fisheye, the fisheye effect is quite limiteed.

As it is unaivalable in my country... I only find expensive ways to buy it (from Japan or from Italy at 120€...)
Too much for me...

So I think more and more buying the Samyang/Rockinon instead. Not as small...
Your comparison gives the rockinon more arguments... I'm not sure I will be pleased by the body cap results.

 

Thank you Yaruda for the comparisons, so I've decided to pre-order this little toy lens. I've played with Robert Wong's files already and know how to correct most of those issues with my workflow. It doesn't add much time and since I don't shoot with a fisheye all day long, it's hard for me to justify a $300 lens (yes $200 if you can get it on sale), so this little lens will do me just fine! And no, I am also very critical of lens performance myself since I own good lenses, but sometimes the only person that make me happy is myself and not my paid clients, this lens is going to make me really happy!! Fun times ahead!!

 

Thanks for taking the time to do the comparo. However, I think the BCL's are not meant to be "real" lenses.... Just some novelty toys. The Rokinon 7.5 is actually a real usable lens... I'll do a comparo of the Olympus ED 9-18 zoom one day to see how it compares with the Rokinon.... That might be a more fair comparison.

 

While I was never interested in the BCL (I absolutely love my Samyang FE, and I think the BCL FE is way overpriced), I just stopped by to say thanks for taking the time and effort to do a proper comparison between these two lenses!

All the best!
 

 

Thank you for doing this, very good.

It confirms what I expected; the body-cap lens is nice if you don't have the Samyang, and its centre is actually not that bad at all. Good enough for those who just like a fish eye for goofing off every once and a while. In many cases for that type of pictures, the centre is most important, the rest less important. And they hardly ever end up as large prints on a wall...

If you really want to see what a fish eye can do, things are different, and the Samyang is a remarkably cheap way to get a surprisingly good fish eye.

Had this body-cap lens been around when I bought my Samyang, I might have very well decided to get it instead of the Samyang. I expected to have little 'serious' use for it, and bought it more because I could afford it, and because I expected to have some fun with it. I was wrong and I use it a lot more than expected now. With the body-cap lens I might never have developed my present taste for fish eye pictures...

 

Thanks for the comparison. Would have been disappointing for Rokinon owners if the results were different, I imagine  

Looking forward to a 9-18 comparison, as that is what I own  

 

I just did that over the weekend. Found an Ambico .5X converter lens with a 46mm thread. I used it on my Sony 8mm camcorder for years. I put it on my Panasonic 14mm.

I didn't get a 7mm result. More like 10 mm. And it was ugly. Vignetting. Edges were blurred.Center was OK.
