Originally posted by cls know some of you here have experience with different systems (Nikon, Canon), and mirrorless systems, which I am understanding are superior for AF and ISO noise than SLR. I have been mulling costing out selling and replacing my Pentax system with comparable Nikon or Canon (not ready to let go of SLR), but it seems a daunting task to evaluate. My gut says the K3iii is really close to the D500 or Canon equivalent, and it will be a huge pain to try to source new gear and sell old gear, and I will lose out in the end and possibly not be measurably more satisfied. I just read a very old thread comparing lens cost/quality in the three systems which was interesting and supported my gut feeling. Any insights into switching systems or is the K3iii putting Pentax in close enough range for speed and AF that it would not be worth the switch?
For lenses, I have:
- Sigma 100-300
- Sigma 17-70
- Pentax manual 50mm f2.0 that needs an upgrade
- Pentax 18-250 kit lens
- Pentax 200 f4 (rarely used)
- Vivitar 90mm Macro with an adapter ring, so manual (rarely used at the moment but I come back to it now and again).
If I started from scratch with a new system, I would want a fast 50, and something in both the 17-70 and 100-300 range, at least. With my current system I am looking to upgrade the fast 50 immediately, and looking toward macro capability and extended telephoto in future. I photograph a variety of things - lots of family and kid stuff, but also wildlife and dog sports. Many who responded counseled me to look at my lenses to improve my experience. I wonder, what would be some recommendations people would make?
First mirrorless doesn’t give better iso performance at all. Certain sensors available only in mirrorless might. But that’s reall putting a very thin hairsplitting difference in more prominence than is really useful.
As for focus - the truth is complex. Mirrorless tends to be where innovation is at the moment. DSLR’s lead for a long time. PDAF on chip helped and yet also can create banding issues in shadows that required a bit of new techniques on the part of raw converters at first. I own an A7rIII and a KP and I’ve had shots where one beat the other and it isn’t always predictable- modern gear is fantastic but it doesn’t have to be anywhere near cutting edge to give great images.
To be honest the lenses you have aren’t a huge investment. Nikon is the most similar to Pentax in DSLR world. Slightly more refined perhaps. Slightly better at a few odds and ends but with Nikon pricing and Nikon is moving away from their SLR mount so new tech will lag. Prices can be quite a bit better due to folks switching to mirrorless however.
Honestly you can gear chase but ultimately you need to decide what you like most. Look at this forum as one major assets to sticking with Pentax. No other gear seems to have this kind of community. That said, the other gear has more tutorials and better support in the mainstream if that matters to you.

Canon DSLR’s tend to have lower dynamic range except for a few later models. That doesn’t make them inferior just be well informed.
