First Experiments with Classic Lenses and 102-megapixels of Fuji GFX 100 – By Tudor Stanescu

I’ve been fortunate enough to own a Fujifilm GFX 100 for almost 2 years. During that time I have not taken full advantage of using this wonderful camera system much. There are many reasons why my GFX 100 has been collecting dust in my office but the main reason is the lack of lenses. Let me be clear, I think there are enough native lenses available for the GFX cameras, but I happen to only own one — the 63mm f/2.8.

Naturally, I’ve gravitated to using my Sony A7R iii or Canon EOS R on my photography projects as I have a full kit of lenses for those systems.

So what’s the story?

Recently I’ve caught the photography bug again after taking a lengthy hiatus from creating on a consistent basis. So on my after-work walk today, there was a beautiful sunset, and I thought, why not try to adapt some of my favourite vintage lenses to the GFX and see what happens? I’m ashamed to say I never adapted any of my vintage lenses to the GFX prior to this. So I ran home quickly and grabbed three of my favourite vintage lenses, and scooted back outside just in time to catch the last few moments of the sunset.

The Vintage Lens Setup

Canon FD 70-210mm f/4 lens

Excited to see what I could capture, I started with the Canon FD 70-210mm f/4 lens, which was double adapted to the GFX through a Canon FD to EF adapter, and then from Canon EF to Fujifilms G-mount. This lens unsurprisingly had little vignetting, considering the GFX is a medium-format camera, vs the 35mm (full-frame) image circle that which Canon lens was designed for.

Helios 44-2 55mm f/2 lens

The second lens of choice was the Helios 44-2 55mm f/2. As one of my all-time favourite vintage lenses, there was no way I was leaving this one behind. The Helios was more easily adapted by using a simple metal screw mount adapter for the Canon EF mount, and again EF to G-mount.

To my surprise, this lens perfectly covered the GFX’s medium-format sensor and there was no vignetting.

SMC Super Takumar 35mm f/2 lens

The last lens in this quick experiment was none other than the SMC Super Takumar 35mm f/2. After covering a wide range of focal lengths with the 70-210mm and 58mm I picked up this wide-angle vintage lens to round out my experiment. The Takumar was easy to adapt as well, and worked the same way the Helios did. However, the Takumar had the worst vignetting out of the three lenses I tested.

The crop factor on the GFX is 0.79, making this lens about 28mm equivalent, which I suppose would exacerbate the potential for vignetting on a lens which was not made to cover an image circle larger than 35mm/full frame.

The Results

Now what you’ve all been waiting for, how did the pictures turn out?!  The results are for illustration purposes, these images were downscaled to about 60% quality and 10% of the original size to save on size for displaying on the website. These are not meant for pixel peeping.

Canon FD 70-210mm f/4 sample pictures

The Canon FD 70-210mm performed great and did a great job reproducing colours. Of course, a lot of this was thanks to some colour correction in Lightroom, but the out-of-camera pictures looked pretty great.

What I didn’t like about this lens where its flaring and focusing. The lens had a lot of flaring when shooting into the sun, which was to be expected. My issue with the flaring was that it looked too boring. The flare had no unique characteristics. After reviewing the photos on the computer, I noticed none of the photos came out in perfect focus. The only exception was one macro shot I took. I don’t know if this was because I was rushed or if the doubling of adapters added too much length between the flange and sensor, making it either impossible to focus to infinity or the camera’s focus peaking was creating false positives. Further testing of this lens and camera pairing is required.

Helios 44-2 55mm f/2  sample pictures

The Helios 58mm was by far the best performer. Combined with the Fuji magic, the Helios lens captured the best colours. I was also able to nail the focus, and of course, the lens performed beautifully in all the areas you would expect. The lens excelled in photographing subjects that were close to the foreground so that you can take full advantage of the lens’s out-of-focus characteristics for the background.

SMC Super Takumar 35mm f/2 sample pictures

Last but not least comes the Takumar 35mm. By the time I got this lens on the camera, some of the best parts of the sunset were over, but I was still able to capture some great photographs.

The 35mm lens performed somewhere in the middle between the other two. The colours were great, and the focus was good. I did notice that I was having some issues with nailing the focus exactly where I wanted. Again I’m not sure if this was due to the focus peaking creating some false positives or perhaps the minimum focusing distance in some of my shots was beyond where I expected it to be.

Due to the more extreme vignetting on this lens, I am not sure if I would use it again as the images would require significant crops, losing too much from the image.

What’s Next?

This spontaneous experiment has inspired me to continue testing vintage lenses on my GFX 100. I am mostly interested in testing them out in a portrait photoshoot in the future as the vintage look will lend itself well to portraiture I think.

Stay tuned to see what’s coming up next on my Instagram!

  1. I have used many vintage lenses with a Fuji GFX 50R and have found many that I love. I do not believe that focus peaking can be “fooled”, however focus is often more critical with such a high resolution sensor. It is also frequently necessary to use higher shutter speeds than with smaller sensors in order to avoid blur from camera shake. PC shift lenses are one of the best options for wide angle lenses that cover the full sensor. Medium format lenses can be excellent. Among lenses made for full frame cameras you will find that many lenses of around 58mm and longer do cover the sensor well. Do not neglect to try cropping as well. Many lenses designed for full frame cameras will cover the square and wide panoramic crops, which provide wonderful possibilities not attainable on smaller sensors, and with so many pixels cropping is no problem.

  2. The FD to EF adapter will be the problem as it needs a glass element to refocus the image as FD has a shorter flange distance than the EF mount. I started with it on my Sony, and when I got the 80-200mm f4 L I compared the two and it was just as sharp, just suffers from chromatic aberrations.

  3. Tudor, I do post and assisting for a portrait photographer who has delved deeply into vintage projection lenses on a GFX 100. Watch this 5 minute video on Vimeo to see a project we produce every year for a local private school. These lenses can produce some amazing bokeh under the right conditions. Make name signs to go with each of your lenses and photograph them before shooting a photo set. Later in the edit stage it will help you determine which lens works best under what lighting. Many of these lenses are only sharp in the center so shoot wide and then utilize the ability of the 100mp to crop and still have plenty of resolution. Good luck in your endeavors.

  4. Tudor, I personally like the heavy vignette. The tree reflection is my favorite. Printed as a 3.5 x 5 with borders on a glossy paper it could almost look like a sort of polaroid.

    I work as a digital darkroom tech for a portrait photographer who shoots with a GFX 100 and he got into vintage projection lenses during covid lockdowns. We have been shooting a special project for a local private school where the 5th graders dress up in historical costumes for a class history project. Using the projection lenses on the GFX adds a nice effect to the overall look of the final prints. The teacher personally hand makes each child’s costume and they are amazing! We had a local studio, Exploredinary, shoot and produce a short 5 minute video. It is posted on Vimeo, here is the link: . You can see how these lenses look with portraiture. The swirly bokeh from a few lenses is almost disorienting! Good luck on your lens adventure.

  5. So you had all these adapters, FD to EF and EF to GFX and M42 to GFX and you hadn’t yet bothered to adapt any of your lenses in the 2 years that you owned the GFX100 camera? How long did you have the adapters for before using them? Also, you should know that in multiple spots in the article you referred to the Helios 44-2 as a 55mm f/2 lens as well as (correctly) a 58mm f/2 lens. Finally, if you were able to use the same M42 to GFX adapter for the Pentax lens as the Helios lens, then I’m betting it was just a Super Takumar 35mm f/2. I don’t think SMC Super Takumar is a real thing. Pentax M42 lenses had several different generations as optics and coatings improved: Auto-Takumar, Super-Takumar, Super-Multi-Coated Takumar, and SMC Takumar.
