Posting about another lens that i have adapted! Today’s post is about the Tamron 45mm f1.8.
Where do i even start, this is a fantastic lens that feels like it was made for the GFX system. This lens completely covers the sensor with little to no vignette. The out of focus bits are so soft and pleasant, and the colors this lens renders are beautiful!! With the GFX’s 0.79x crop you get about a 36mm (35.55mm) equivalent with the depth equivalent of F1.4. Please note that this is the depth equivalent, not total light transmission!!
This lens is razor sharp wide open and somehow gets even sharper stopped down. A really cool and helpful feature of this lens is the built-in stabilization, which works wonderfully on the GFX50R (no ibis)! Also it’s weather sealed!! THEN ON TOP OF ALL OF THAT you can find these for about $200 or so online!!
NOW, i do need to speak about the cons, there’s not much but i do need to speak on this. The autofocus is definitely on the slower side. Not as slow as other lenses i’ve tested but still slower than the Canon 40 or the Sigma 50! It’s also a bit hit or miss, i usually get a keeper rate of 7/10 with this lens. I feel like sometimes the lens just doesn’t like to play well with either the fringer adapter or doesn’t work well with the 50R’s contrast based AF. I KNOW I KNOW the fringer was designed for the bodies that have phase detect, but i can’t justify dropping that much on a 100 series camera. not yet.
This is a fantastic offering, and a SHARP 35mm equivalent for the GFX that produces some of the most beautiful images i’ve ever created. The slower AF is a pain but it definitely helps you to slow down which helps you stay more involved with the photos you’re taken. You gotta remember that this is “medium format” so you can’t really spray and prey like you can with smaller formats.
This will be a lens that i will always recommend to people try when they’re wanting to adapt non native lenses to their gfx bodies!
