I had this lens lying around from another project and I was eager to see how it performed with the C300 MkII's Slow and Fast motion crop mode with a relatively cheap B4-EF adapter.
This is a non-glass and non compensating adapter.
Interestingly, I found that it had equally as good or better results in Normal Quad HD/4k recording mode when cropped in slightly in post.
There isn't anywhere near as much fringing and aberration as I expected, and although you can see an unsharp area around the edge at full wide, it's not nearly as bad as some examples I've seen and is most noticeable at wide open f1.8.
The image can be cropped further to mitigate this.
The built in doubler was crucial to the lens delivering a good image.
Without it it becomes extremely soft and bloomy between f1.8-5.6.
So much so that I haven't even included footage of it in this video, but I will in another.
I'm pleased with the results from this and I will consider using it for the right projects. Perhaps documentary or run and gun work.
I really like the zoom range compared to something like the Canon 24-105. (I have a comparison of these in my other video).
In this example the lens was powered by a V-mount battery via d-tap and adapter cable.
Particular points of interest are:
- f1.8 is to be avoided where possible but usable in some circumstances and could be good for an older soft dreamy effect.
- Some sharpening helps to resolve more detail.
- f4 / 5.6 is about the sweet spot as expected. Towards 11/16 you start to see any dust etc inside the lens (and this is a pretty beat up one)
- Decent Lens support is a must, in particular with this crappy adapter which would undoubtly put severe stress on the EF mount.
I used a basic rail mounted one, but it would ideally mount to the lens or adapter. (e.g MTF services)
- Cropping in post still renders a greater than HD resolution if you process the images differently (such as in a 4k timeline).
- I used an external monitor with custom crop/framelines to help with framing the intended crop. (you can bypass this if you use S/F crop mode).
- S/F crop mode highlights noise and softness of lens more.
- You'd want to consider the processing power and time required to convert footage.
- This lens was noticably warmer than the EF glass we have.
