I just bought the GFX 100S, and I went looking for information to see if my 8-15mm Canon L-series lens would work on it, as the adapter I bought did not list the fisheye as a compatible lens.
It's a quirky lens that I wasn't even sure I'd like when I bought it for my 5DS. I found that in the right context, the results are eye-popping! I've got some stunning shots from inside Sagrada Familia.
I can't wait to take it and my new Fuji aurora chasing soon.
Thank you for this video!
Glad it helped!
I've just bought this lens to adapt to my Sony A7riii and A7rv, primarily for underwater use, so have been searching reviews. This was by far the most interesting and informative review. I really enjoyed it; and the cathedral shots were stunning.
Thanks - Glad it was of interest
My latest fisheye ‘walkabout fun kit’ is the TTArtisans 7.5mm f/2.0 on my Fuji X-E4. I can perfectly stitch two or thee hand held shots using PhotoShop with the “Spherical” rendering and “Geometric Correction” settings. Cheers, David Myers.
There are some interesting lenses from TTA
Good review and great shots Keith.
Thanks
Fabulous images Keith! This video is a ‘must see’ for all newbies that occasionally suffer from ‘Photographer’s Block’! I actually drew a fish-eye Image for an art college project before I was into photography: The reflection in a chrome hub cap! I’ve never been without one of these lenses ever since!
Thanks - they are often misunderstood in what you can do with them...
I really enjoyed this video, particularly since you showed so much of your work.
Glad you enjoyed it! - when I was looking at doing it, I realised that a lot of people might not know much about what you could do, as well as my testing of the 8-15
Keith, Thank you so much for sharing your experience and thoughts I thoroughly enjoyed it
Thanks - I was just going to cover the lens on the GFX, then thought that perhaps a lot of people might not have seen many of the things you can do with fisheye lenses...
Thank you for a really interesting video, I was definitely of the “one trick pony” opinion but you’ve certainly shown me otherwise. Like you I have a GFX 100s but as a former Nikon user (sold all the kit when I switched to Fuji) I never had the chance of trying any 35-mm lenses on my camera.
Like you I’m eagerly awaiting Fujis tilt/shift lenses, landscapes are my main thing nowadays and even though I use focus stacking quite a lot I find myself wanting the possibility to shift more than I used to.
Glad you enjoyed it! I had quite a few people ask me about FE lenses...
I was going to defer looking this until later, but thought I’d take a peek … and was held to through the end: lots of meat here. Marvelous photo examples: ‘They aren’t the one trick pony you think they are.’ I have found your comment about having more resolution to work with has been my experience. Sure, any imperfect focus and camera instability becomes apparent, but only when pixel peeping. When both are correct, you have a lot to work with, even when cropping. One claim against higher resolution sensors is that they are susceptible to “more noise,” but that noise is proportionally high resolution, and easily removed.
Thanks - glad it was of interest!
I picked up my 8-15 2nd hand very cheap and it was almost new condition. Fantastic lens!
Yes, it's an expensive lens to have sitting around when people decide that they're not using it at all ;-)
Loving your videos!
Thanks!
Thanks for doing this cutting edge review, Keith! Lots of great ideas! This camera a so much fun! It opens up broad vistas, literally - wider field of view for fisheyes and regular wide-angle lenses. The Canon 17mm TS-E (tilt-shift) becomes 13.5mm, and the Laowa 15mm shift becomes 11.5mm! The fisheye at 33mm x 33mm 1:1 on this big sensor will be great for the ceiling of a cathedral, doorways, astro skies, etc.! It’s great to see the extra height advantage of this oversized 4:3 ratio sensor, which is especially noticeable in your inside, staircase photo, which could be very useful for some images. Those who shoot real estate photos of bathrooms, small kitchens, etc. can use this wider and especially taller sensor to get the shot.
I’m also thinking that a fisheye could be used to get the same effect as a shift lens if we shoot with the sensor parallel to the buildings, keeping the buildings’ walls looking like they’re tilting in, using standard defishing, no lens correction necessary. If we keep the camera perfectly level, not tilted up when we shoot buildings (or trees), the really wide field of view can capture some pretty tall buildings without having to be tilted up. The image can be defished, and the upper part of the image can be chosen in the crop, containing the tall building or height of the room.
Does that make sense, Keith? And I have a question. You told me earlier that Fisheye Hemi only works in 3:2, so I’m assuming that’s why you chose a 3:2 crop in your outdoor sidewalk and buildings image. Once you defished the vertical lines, then you cropped it again to get something close to a 2:1 image, a nice result.
I’m wondering why you didn’t line up your original 3:2 crop up to the sides of the sensor. Was that a stylistic choice? You could have cropped to the sides of the sensor, and Fisheye Hemi would have worked, correct?
Does Fisheye Hemi require us to do the 3:2 crop centered vertically (centered with the equator), or can we do the 3:2 crop at the top of the sensor instead, for example?
When fully defishing with other software, we can just defish the entire image, but Fisheye Hemi doesn’t allow that.
This camera is a dream come true for me. So many new creative possibilities! Really wide, 65:24 panos can be done with this too in one shot, for landscapes, cityscapes, etc..
I hope you change your mind and try some of the camera’s LARGE SIZE crop options someday, even if it’s just to show viewers what can be done when using them. When shooting in RAW, the entire sensor is recorded anyway, so we can still crop anyway we want in post.
Thanks again for doing this very insightful video!
Thanks
The 3:2 crop was as much limited by me remembering to take screen shots - I do these videos with no script, which is why I always say to check written versions [when I get round to finishing them ;-) ]
FEH works well, when i works, but some experimentation is needed...
That 47 foot long mega panoramic (@ 26:34) you took looks incredible! I can't see it well in the video though. Is there any place online I can get a better look at it? Did you ever happen to make a video explaining your process for making it?
Linked in the notes...
A detailed article about making the 14 metre print
www.northlight-images.co.uk/making-a-14-metre-photographic-print/
There is a zoomable version of the image on the site too
Long pre-dates me making videos... ;-)
I can imagine that 44 inch, square prints of the circular images are a nice size! Sometimes 24 inch printers aren't big enough, especially for square and 4:3 images - and for canvas images that need extra canvas for wrapping around the frame.
In Ken Rockwell's review of the lens, "Canon 8-15mm f/4 L," he shows how to change the black background to white in Photoshop, which can sometimes be preferable, especially when shown on a white page online or whatever.
Round metal prints are available now too. I'm still no fan of metal, but these round, metal prints are impressive - kind of like the porthole in ships.
I wonder if a round, paper print can be mounted somehow also, forgoing the square box around it.
How would one even cut the print perfectly round?
Compass [string, sewing needle and pencil] and a fine jigsaw did fine for one for laminating onto board. Cut the circular board [fine jigsaw], laminate and trim circular with a sharp knife
- I didn't do this myself though so couldn't say how practical it would be.
Personally, it just looks gimmicky, but tastes [or lack thereof] vary widely and I've never let tackiness get in the way of a sale ;-) :-)
The black/white surround is just a normal circular selection in Photoshop...
@@KeithCooper Perhaps the mounted round print looked tacky because there was no frame. Making round frames from wood would probably be cost prohibitive, but I remember seeing *oval* prints of Jesus that were framed in wood more than half a century ago.
As you know, picture framers buy straight pieces of wood framing sticks, and then cut them to length, which can't be done for round frames.
Many picture frames are made from some type of plastic instead, which I would think could be easily made into different sized, completed, ready-to-go round frames if this style ever becomes popular enough.
Awesome video! What is a good software for dealing with fish eye images? Ever tried Hugin and the projections?
Thanks
For me - just the software I mention...
Not tried anything new for a while
I wonder what might happen if you used Adobe Generative Fill on the "missing" corners.
The problem is the fall off just before the black bit. The 180º field of view and projection means detail is very crunched up.
You can fill the space, but it becomes meaningless once the image is processed
Hi Keith, Thx for these out of the box refreshing photo style explanations. After watching this video, I've got some projects in mind for circular pictures. May I ask you the focal range the ef 8-15 projects a circular image on a FF 35mm sensor as well and on a GFX one ? Thx in advance
Glad it was of interest
See my original 8-15 review for 35mm coverage info
www.northlight-images.co.uk/canon-ef-8-15mm-f4-l-usm-review/
On the GFX, circular is ~10.5mm for this lens
First class answer. Many thanks@@KeithCooper
Thanks for the video. I’m working commercially in the VR industry and I’m curious if a gfx 100s with a fish eye could give me higher resolution results in better quality and fewer shots than working with a x-t5 with 8mm lens. ATM I shoot 8 pics slanted and a ground pic to get my equirectangular image. Which lens could I use to try this approach on a 100s?
You need 11mm on the GFX [+ 8-15mm] to get a maximal circular [180º] coverage - this needs six pics including top/bottom
This is the device I'd use
czcams.com/video/Xqgh9jcUQ08/video.html
It might be possible to use a longer focal length on the 8-15 to get more coverage and hence more megapixels of image. Depends on software
Definitely one left as an experiment for the viewer, since I don't do such stuff commercially ;-)
Keith, have you used or seen reviews of the Canon EF 300 f/2.8 is, Canon EF 400 f/2.8 is lenses on Fujifilm GFX? I can't find information about this couple anywhere. What kind of vignetting does on the GFX sensor produce? These are the best Canon lenses and are cheaper than Fujinon GF lenses. I want to buy it, but we don’t have rentals for testing.
If you can make such reviews, you will be one of the first on this topic. Good Luck. Eduard.
No idea I'm afraid - I don't use very long lenses at all
Very interesting Keith. The tree image looks promising ,-) but for me, no buildings.
Question: do you think it is possible to use this lens in close-up or near macro, for example with the Fujifilm Mcex 18 and/or Mcex 45 macro tubes, for the GFX system? Thanks.
Thanks - The buildings and interiors are often extras I'll include - marketing departments often like this sort of stuff ;-)
I don't think the 8-15 works well with tubes - but I've not tried [I can use my Canon EF mount tubes]
One to check when I'm back in the office...
@@KeithCooper Thanks Keith. I use the Canon MP-E 65mm and the Zeiss 2/100 Makro-Planar on the GFX with the Fujifilm tubes, with good results.
Perhaps those fisheye lenses are more problematic on the GFX. There are ultrawide-macro proposals from Laowa ,-) I just remembered, that maybe they can be adapted to the GFX, at least in 35mm mode, in case they do a lot of vignetting.
The 8-15 does not work at all with tubes - just tested on my 5DS
Even the thinnest focuses on the front element.
@@KeithCooper Thank you very much. Maybe the Laowa ultrawide macro...
Interesting topic. You didn't mention which of these two lenses provides better pixel-by-pixel photography and which one you use more often in GFX?
What two lenses? It's a zoom
@@KeithCooper I looked at the prices now. $150 Canon EF15 f/2.8 fisheye. $400-450 Canon EF 8-15mm f/4L
The 15 was very flare resistant - excellent lens
See my original review [still not used the 8-15 much on the GFX]
