On the 10th of August I went out to a nearby parking lot as I’ve done before and took pictures of the moon. Over the past few months as I had been using the Tamron 150-600 I couldn’t help but notice how the reviews I read were turning out to be true. It’s a great lens overall, but you really lose sharpness past 300-400. They do have a zoom lock switch that only works when it’s at 150, or right around that middle spot. I think 400. I no longer have the lens today otherwise I would just grab it and double check.
It becomes fairly apparent when you’re taking pictures of the moon at 600mm.

But also if you miss your focus. That’s not going to help matters.

Much better. And this one is at a much slower shutter speed, smaller aperture. But it still was lacking what I wanted. At full resolution you really don’t get all the details. Or if I cropped it and zoomed in, it’s just kind of lacking that crispness that I wanted.
And here’s what happens when you set it to the longest exposure time, and just jiggle the camera all over the place. Looks like a signature.

That’s it for that day. Not much else to post except more pictures of the same type of thing. I know astrophotography is a whole other style. And people use different techniques for it. I’d love to try it some day, but that’s a whole other type of money spending venture I can’t finance.
