A nice set and I like the use of borders.

The last one has an almost sinister snake like head and neck look about it. Does anyone else see that?

The second one also appears to have a dragon or griffin type head look down the post.

lol...

And the when it's dead, eat it!

Love the bubble bokeh in the second shot.

My eyes aren't what they used to be and so I may not be the best judge but to be honest I don't discern a vast amount of difference in them at the size they are reproduced here. The 28-105 usually has lots of praise heaped on it. If you think yours performed poorly, especially at the price comparison, maybe your copy just isn't one of its best examples. Never-the-less, I think unless one pixel-peeps, or sharpness of the subject is going to be critical, they all look acceptable. Just my thoughts so please don't be offended.

Very nice. I particularly like the last one. Highlights perhaps a bit to bright in the first but very nice compositions.

There's a couple here that might be worthy of inspection. Not cheap exactly, but then none are!

Good hunting.

Nice to see you around again David.

Best regards,

Another gem of a photo captured with a legacy gem lens. Justification for my hobby of collecting older glass and the great satisfaction that comes with using it. Can't recommend it enough.

Just Sublime.

Glorious morning beautifully captured.
