Originally posted by 2351HD Thanks for all the responses. To clear up a few questions below:
- I sold the 645z system for two reasons, lack of lenses to suit my needs (no ultra-wide for astro, no manageable 70-200 type lens either), lack of interest from Pentax to grow the lineup and also I damaged my hand last year and needed to downsize my kit a little in weight. I found when I travelled I was needing to take both the 645 kit with 3 lenses and the 5D4 kit just to cover my bases for the shooting that I like to do. I want one system that can handle ultra-wide to tele and everything in between.
- Canon does have an adapter, but there is none available anywhere. I have a R5 in my hands for testing and need to make a decision to keep it but I can not even use it with my lenses, only a loaner 14mm samyang that I have been given, which is a terrible lens
- I know I can use my EF lenses adapted, but ultimately the move to RF glass is on the cards. I can build an entire pentax system with a K1, KP and all lenses for less than the price of the R5 and 70-200 lens
- I will not be moving to Fuji MF, do not like it one bit.
- Having used the K1 when it did not have the electronic first curtain shutter, which is important for perfectly sharp images, I do not know what the K1 with latest firmware or the K1mkII is like now, could be a different beast. I sure did love the controls and feel of the camera when I used it back in 2016. Is the AF any better on the mark II camera? I found it lacking with the 15-30 just in single centre point focus, it would not lock on to the same spot every time and I had a bunch of missed photos.
The cost of a R5 kit was also a big deciding factor for me.
Guessing at the cost of their RF 35mm 1.2 L, an R5 body with 35/50/85 1.2 L is going to be roughly $12k; again guessing at the cost of Pentax's D FA* 35mm 1.4, a K-1 with 35/50/85 will cost me less than $6k. That alone is a big deal for my purposes, 50% of the cost and I'd say about 90% of the performance. Of course, this is when it comes to still photography, if you are interested in video and/or fast moving subjects then there is no completion between to the two systems. Don't get me wrong, I really like the Canon R system and was thrilled with the quality of the RF 50mm 1.2 L and 70-200mm 2.8 L, but the difference in cost is far too great to justify the fractional difference in quality. And in some cases I would still take the Pentax system for its Pixel Shift implementation and the fact that I have an option for an optical finder (I almost always work on a tripod using the rear screen so a high-performance EVF is kind of redundant).
