Every once in a while you run across a great lens at a bargain price. The Tamron SP45 is one of those lenses. I tested my copy on a Nikon D750 (24MP.) In those tests (performed 03/2018) I found the lens to be extremely sharp wide open, at f1.8, edge to edge with sharp corners.

My salesman Frank Brown went over and above the level of service I expected from a mail order company. This is my second Nikon lens purchased in the last 12 months and I can truly say that I will shop nowhere else.

There are plenty of reviews about this lens on YouTube etc and I would suggest watching a few of them. Personally I love this lens, it is sharp at f1.8 and extremely sharp from f2.8 on wards. I used Focal software to micro adjust the focus which gave me a reading of -5 and it is now spot on.

Wide range of usages, given its pictorial and optical qualities, weather sealing, close focus, and stabilization. Very convenient FL, by the way. At ease with portraits, social events (despite bulk and slow AF, but MF is good enough), architecture.

Image quality is very appealing; I'd say "delicate rendering", as contrast may be milder than with, say, recent Zeiss lenses; Users should not get blinded by absolute resolution figures (yes, Otus is better, so what).

Size and weight

So happy with this lens, its sharp like razor, thanks for tamron.

Perfect, received the item after only two days.

very sharp F1.8 with VC give you options more than an f1.4 lens

Want some attention in this DSLR lens-filled world? Introducing a record-setting lens has been a popular business strategy lately and Tamron is once again putting their name in the record books with the Tamron 45mm f/1.8 Di VC USD Lens.

The open aperture is set to F/1.8 with optimized critical properties at a higher level: superb optical performance coupled with a VC system, a shorter MOD, and a well-balanced form factor.

It's the closest thing to a stabilised 50mm lens that also manages to be lightweight and high performing...

Nice and light; Weather seals; Lovely bokeh

Not quite f/1.4
