I recently bought a Pentax 70-200 and have noticed excellent AF and image quality/detail. So, I have been looking at the Pentax 150-450 to possibly get similar performance.
I would like to find out if the Pentax 150-450 is a better performer than the Sigma 150-500 DG OS.
I also would like to know if the Pentax 150-450 is fully compatible with the K-5IIS.
I have a K-1 II that I use my Pentax 70-200 with, my K-3II that I use my Pentax 16-85 with, and I currently have my K-5IIS on my Sigma 150-500 DG OS. I tried the K-1 II on the Sigma 150-500, but I found that it performs astoundingly on the Pentax 70-200, so I am going to keep it on that lens.
I have my K-5IIS which also performed well on my Pentax 70-200 and Sigma 150-500, and I am possibly looking for a new super telephoto lens to to use it with. So I need too know if the Pentax 150-450 is fully compatible with it (K-5IIS) and if it would be a worthy upgrade to my Sigma 150-500.
I would also like to note that I like to use aps-c camera bodies on my super telephoto lens due to the distance and megapixel combination that I get. So if I one day decide to get a new flagship Pentax aps-c body, it would replace the K-5IIS for super telephoto. As far as what I use my K-1 II for, as I said the AF and image quality I get from it when paired with my Pentax 70-200 is astounding, so I am going to use that as a dedicated combo.
Thank you for any information pertaining to this post, and have a great day.
