Some very good points made thus far. I also agree, that from certain vantage points, the options for the poll have the potential to create some not entirely accurate data. However, I just wasn't sure how else to convey the points, as I didn't want the poll itself to get deep into the weeds by having 10 different options. Figured I'd leave the nuances to the actual discussion portion, as far as added insight goes.
Just to add a bit of background as to what prompted me to pose the question. I shoot Sony, Canon, and Fuji together, so I pay attention to what's going on with all three brands. One of the things I was really looking forward to for the RF system was the release of their fast 35mm prime. When it was finally released recently, what came to light fairly quickly was that the lens leaned very heavily on baked in lens profile corrections. If anyone is interested in further detail on this, Sam Hurd does a great job starting at around the 3 minute mark of his review on YouTube.
The initial selling points seemed to be that the lens was video-centric due to low focus breathing and the new VCM focus system, and the size/weight. However, the distortion is fairly high, and actually shaves off roughly a 400x260 resolution loss due to the shaving of the sides of the image in correction. This, before we even get to the vignetting. Over on the Canon forum, there seemed to be a decent number of members applauding the smaller size of the 35 without concern for the optical shortcomings, which really surprised me.
In contrast, the Sony GM 35 seems to do a much better job with regard to distortion sans having to rely on baked in corrections.
I've also been playing with the Viltrox 27/1.2 for the Fuji system for the last few weeks, which is another lens that is on the larger side, but is very well corrected without the need for any profiles (which I'm loving). But again, I've seen some members mention how the size of it relative to other Fuji lenses is off putting.
All of this got me thinking more about the philosophy behind these designs and how most of us around these parts feel about what is more important.
Personally, I'd like for there to be high IQ medium speed primes that are compact, alongside their larger siblings that are there to push the envelope of what is possible with modern engineering and design. What I don't like, is what Canon did with the RF 35 VCM. The only way I'd change my position on this, is if they also release their previously rumored 35/1.2 that happens to be a statement lens of epic proportions....Show more →
Well said!
I also think there is room for both, but if I had to choose I'd probably go with a reasonably software-optimized lens like 35GM.
On the other hand, it really comes down to each case. Continuing with 35GM, I really like what it has to offer for its size & weight but there are properties which I like more on the considerably bigger and heavier Sigma 35/1.2DN. It's not really about faster aperture, but the quality of blur is simply nicer on the Sigma at equal apertures. Sharpness / contrast is similar, if not better, on the GM though ...
