Hey all, thanks for so many wonderful and funny comments!!
I don't know what that fungus is yet, but as I was taking a photo of it one of my dogs came over and licked it, that's why it's a bit wet on top!
The geode is just weird... it does have great colours, but it did not photograph at all like I expected.
The "Lava Atoll from Space "and "droppings from space" comments made me howl.
Only the Atoll was shot with the tamron, all the rest with the 50 1.7 on the K5 and I was blown away by the colours, tones and bokeh, and the clarity and textures on those white flowers.
The K5 made the 50mm a very nice lens to work with.
Thanks all for having a look and commenting
