 p.2 #6 · Adapted vs Native. Any real tests out there | |
before dismissing my opinion as trolling, I'm honestly only here to help.
I'll give you the benefit of the doubt then, but still want to know why it's so difficult to understand that not everyone is you, and not everyone share's your same justifications to "just switch all your lenses over and be happy"? It's been clearly stated that some can't afford it, others are still using those lenses on Canon cameras (i.e. best of both worlds like myself) while still others (again like myself) prefer the performance of those Canon lenses on a Sony body.
All major primes are here, 28, 35, 50, 55, 85, 90 (and soon 135) in many flavours, they are all sweet and well priced, some (35 and especially 55) are excellent and superior to their DSLR counterparts.
This is why I fail to see any benefit clumsily adapting third party options from completely different systems.
Our Sony systems cost the same as our Nikon systems and are cheaper than Canon (Canon equivalent bodies and lenses are VERY expensive).
Canon's 40mm F2.8 currently sells for $179, where the Sony / Zeiss 35mm is $798. For a street photography lens, both are comparable in terms of focal length, maximum aperture, sharpness, weight, size, etc. The exception is adding the adapter makes the 40mm go from being slightly lighter & shorter to slightly longer and tripling in weight... still barely noticeable if I had to walk around all day with it attached to an A7R2.
The first time I had an opportunity to adapt the Canon 40mm, then compare it to the Zony 35mm, was yesterday afternoon. For a somewhat scientifically blinded control, I sat my wife down in front of the computer and asked her to pick the best images and randomly showed her Sony 35mm vs Canon 40mm pics without telling her what lens was being shown...where I alternated between unedited RAW and jpeg's in the comparison. I carefully controlled the light to ensure the situations were equal, threw the camera up to a steady shooting position, then rapidly fired. When an adapter failed to compete with the native lens in AF speed, I disqualified it from the test and declared it an automatic loser (i.e. Sigma MC-11)
Most of the time, my wife said they were both (Zony 35mm vs Canon 40mm + Metabones IV) equally good. A few times though, she did say there was something more inherently pleasing about the Canon 40mm. The only time she picked out the Zony 35mm was the low light photos, but I had to discard these results because it was obvious the 35mm wasn't metering properly. In other words, the Metabones + Canon 40mm appeared to generate a proper exposure at ISO 6400...where I intentionally selected Aperture Priority to determine if there would be any misc. differences between adapted & native lenses throughout the various f-stops.
I didn't have time to go back and re-shoot these low light pics over again in Manual mode. Even though the Zony 35mm was clearly underexposed at ISO 4000, it naturally displayed less noise in the image and may account for the preference for the 35mm. For anyone interested, I used both Metabones IV & Sigma MC-11 adapters, but had to abandon the Sigma b/c it struggled to focus quickly in low light....performed well otherwise. Further testing is needed for me to personally declare a winner, but suffice it to say, the Canon 40mm F2.8 appears to compete well with the Sony / Zeiss 35mm.
While there may be an exception or two where the Sony equivalent is cheaper than its Canon Counterpart, most all of the Canon lenses I'm using right now have Sony replacements coming in at around $600 higher-- as in the example I provided above.
the manufacturers options outperform any adapted alternative (on Sony bodies) and aren't significantly more expensive, sometimes cheaper.
Just switch all your lenses over and be happy
Wow, seriously? Again, when you make statements like these, it's hard to take you as someone trying to be helpful. For me to "just switch" would cost over $15K USD b/c this would mean first taking a beating on all my perfectly good Canon lenses over on the 'Buy & Sell' board, replacing them with a significantly more expensive Sony equivalent (that I don't yet trust), followed by incurring the wrath of my wife who shares those very same lenses and refuses to use anything but a Canon DSLR. Several years down the road, when the Sony prices drop a little and the track record has been established on the latest lenses- maybe.
