That's a very pleasing result Mick. Your post is timely for me as I've developed an interest in vintage camera lenses. There's an absolute stack of them available on Ebay etc. at very reasonable cost,
certain examples such as the SMC Pentax 135mm F 2.5 & earlier Takumar 300mm F4 lenses have good reviews & enjoy cult status.
It's a toss up for me between them & the newer Samyang/Rokinon 135mm F2 .... I think I have the widefield bug
.
Great image with the vintage Tamron though

Cheers,
