p.2 #1 · p.2 #1 · FE 35mm f/1.4 arrived - looks well-centered to me. Your thoughts?


Tried to compare the sharpness of the EF 35L II to the FE 35/1.4 just a few minutes ago. Thought I'd put the raw files up in case anyone wants to have a look. I'm honestly not even sure that this is a good test. I felt like it was as the sign is made of wood and the lettering shows a lot of contrast. The issues are the angle of the sign to the camera (perpendicular? no idea, I tried) and that I slightly repositioned the tripod to account for the size of the adapter (I didn't remove the tripod mount from the adapter and therefore couldn't mount the camera directly to the tripod with the Canon lens). Hopefully, it's close enough that some insight can be provided.

I have my own conclusions (again, this was just a sharpness [and contrast, I suppose] comparison) but I'd be interested to read y'alls conclusions, if you're willing to take a look.

35L II is first, 35 ZA is second

I think the 35 ZA has more contrast which results in a perception of greater sharpness, but I am not sure what to make of this as I think the black points may be different in the two files. I think the 35L II could be quite a bit better with just a small tweak to exposure, levels, or curves, whatever you like. Both files look really good for this type of shot. That is my take anyway.

It seems to me that the wood grain has more detail/sharpness with the Canon but that the black letters have more contrast with the Sony.
I'm happy with both, but in different ways.

I just picked up the 35/1.4 from the UPS location where it was held, snapped a handful of images while I was taking my dog out to pee (all handheld, which is obviously not ideal but IS how I'll use the lens) and looked through them. It doesn't appear to have a "soft right side" to me but I'd certainly welcome more experienced eyes taking a peek.

All of these images were taken at f/1.4 as I figured that's where any soft sides would show the most dramatically. If not, please let me know!

The image with the pool showing was

I think if the issue is not immediately jumping out at you then you're fine. Most of the decentering examples I saw posted early on were fairly obvious without having to resort to 100% view. Congrats!

Oh, I'm happy with the centering of the lens. I've moved on to comparing the sharpness!

Thanks for posting the comparison pics. Quite a difference in sharpness. But I'm glad that the Sony has at least one advantage over the Canon (in terms of contrast).

it doesn't take an 'experienced expert' to tell you what you can see - plus, you'll have the full res images to make the best inspection.

one thing w/ these boards - if you go looking for problems, someone will find them, even where they don't exist.


I agree, personally I've had two copies of this lens I've bought (one new and one used) and I've had great experiences with both. To MY eyes...I'm sure someone would pixel peep and say otherwise but my personal experience from my lens copies has been great.

Post some comparison shots showing their OOF rendering at mid distances if you can.

Just so I make sure I'm on the same page as you, you're looking for an image similar to the one I posted of my son, where the subject is close and the area 6-15' away (mid distance) is out of focus, right?

If I am shooting the FE 35 at 1.4-1.7, I find AF-C or MF gets more shot in perfect. I hope you manual focused when comparing to the Canon.

If you still have both lenses, it would be great to see rendering at around 2m and 3m showing both lenses wide open with different backgrounds.

I was going to provide several samples while I was out with the kids today getting ice cream, but literally as soon as I pulled the camera up to my eye for the first shot, I felt a raindrop on my head. So I snapped that one, swapped lenses, snapped the next, put the camera in the bag and jumped in the car! lol

Here are the two I managed to get...

That's actually a great test subject! . Aside from the EFCS (I would just use silent shutter), I think they were not focused on the same spot and that would affect OOF rendering. Did you use MF or AF? I would use the former.

I see. The FE 35 is not easy to MF with its focus by wire.
I usually do a best of 4 attempts.

Anyway, thanks for the test! The EF 35/1.4L II seems to be very well color corrected.

So I've decided I don't like the manual aperture ring on the FE 35/1.4. I've bumped it way too many times. So, I just set it to auto and I'll control it from the camera.
I went back and re-shot those test images, checking for critical focus on the bike seat. I first shot at about 2+ meters with each lens and then I moved back about a meter and took more pictures. Unfortunately, during the lens swap, I apparently nudged the aperture ring and took the pictures at f/1.6. If you still want them, let me know and I'll upload the FE @ 1.6 vs the EF at 1.4.

Anyway, here are the shots around 2+ meters at f/1.4 for both lenses...

Thanks Jonathan!

Here are my thoughts based on these two images:

1) The Sony has smoother rendering at this distance. However, this is only true in the center/mid area.
2) The Canon is noticeably sharper at f/1.4 with more contrast as well
3) The Canon is very well controlled for axial CA. The FE is NOT.
4) At the edges, the Canon looks much smoother.
5) The Canon is free of onion rings on bokeh balls.

I like the Canon better overall but the FE is slightly smoother at mid-distance. (except for the edges)






Canon is sharper at f/1.4







Sony's OOF rendering is smooth at center and mid area







The Canon is well corrected for LoCA







The Canon looks better at the very edge (smoother)

Not much to debate about in these comparison images. It is what it is. Good samples Jonathan! I'm sticking with the native FE 35 F1.4 myself. But can certainly see why someone would want to adapt the Canon.
