Tamron 35mm f1.4 SP Di USD
« on: September 14, 2019, 10:39:36 am »

The online reviews of the Tamron 35mm f1.4 SP Di USD are stellar (most notably, the Lens Rentals MTF measurements).  Anyone in this forum who owns this lens who can comment on image quality and quality control (ie., did you get an asymmetric lens?)?

Also, any speculation on whether the Tamron 35mm f1.4 SP Di USD would be notably sharper at f/8-11, which is where I normally shoot landscapes on a Nikon D850, than the Sigma 35mm f/1.4 ART?

Thank you

Sorry, no first hand experience but I share your interest in this lens.

Besides its technical qualities, I was also impressed by its bokeh.

Cheers,
Bernard

If you look at dpreview, you can download sample RAW files taken with a Z7 and FTZ adapter. 

There is one shot of a city at f/1.4, and the frame is sharp edge to edge even at 1.4.  I would think this lens blows away the Sigma. 

The Sigma is a bit dated, and was surpassed by the Canon 35mm 1.4LII (which I use on the Sony with Metabones adapter).  I would say this Tamron is probably even sharper than the Canon, but isn't corrected for out of focus fringing as nicely as the Canon is.  The Sigma doesn't match the Canon.

Tamron says this is their no compromise lens.  They told their engineers to create the best lens they could.  It has a bit of greenish out of focus fringing compared to my Canon (the Canon is like an APO), but looks to be the sharpest 35mm prime, considering the samples I've seen at f/1.4.
