I read several reviews saying they had some focusing issues with this lens but I recently bought the 85mm 1.8 VR and was very pleased with it after similar reviews. I LOVE this lens, the sharpness and color are very good. The AF has give me zero problems.

Pros: Great prime lens for a very good price. Cons: Heavy but understandable due to better glass Other thoughts: This lens makes a great addition to anyone's collection.

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.

I'm really enjoying Tamron's entry into the 50-ish prime market. 50mm is my most used prime focal length, but I'm used to Sigma's implementation which seems to have a slightly wider field of view than Canon's 50s, so the 45mm length of the Tamron feels very natural to me.

Consistent Output; Rugged; Strong Construction

Slow Focus

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

If you've always wanted your 50mm prime lens to be just a little bit wider, Tamron has you covered. Its SP 45mm f/1.8 Di VC USD ($599) has a focal length that almost matches the true normal diagonal of a full-frame camera sensor (43mm).

Very sharp; Minimal distortion; Wide maximum aperture; Optically stabilized; Good close focus capability; Weather-sealed design; Available for Canon, Nikon, and Sony SLRs

Shows color fringing; Edge performance isn't as strong as center; Heavy for its size
