Hey all,

Back in March I purchased an A7iii, FE 24-105 G and 50mm f1.8 kit. I used it for a few shoots but ended up selling it a few months ago because I realizEd that for the cost (about $4,500-5,000 CAD), it just wasn't worth it for the number of times using it. I got most of my money back but I want to grab something for an upcoming Hawaii trip. I also briefly (few days) had an RP with RF 35mm (in march as well) which was good, but not as good as the A7iii, so kept the A7iii.

In what ways did you find the RP not as good?

Primarily for me was the tracking autofocus that was not as good, but this was back with FW 1.0. I dont' care much for FPS (yes the A7iii is incredibly quick), but it's more the ability to just track a moving subject. I'm more familiar with Sony's system and knew the A7iii had the old "tracking" system for objects, while the A9 and a6400 had the new object tracking system.

This is important for when I take pictures of our dogs. Yes Sony has animal EyeAF, but at a pace a dog can move around the yard, there's no way that the Sony was able to always lock onto the eye, and since it's not a human, it wouldn't go back to Face detection like it would a person/child. When it lost the Eye, the Sony would often scan the frame and not always find the dog moving within the frame.

From what I hear, the object tracking is almost like glue on the 6400/A9 and should work well with dogs.

From some of the videos I was able to find on the 1.4 FW, the tracking seems a lot snappier on the RP than it was when I had it.

I really liked the RP ergonomics, user experience, touch screen, etc and got some good shots with it, but was bummed about the Eye AF, tracking, etc (this was with FW 1.0).

Here's what I prefer to shoot: Landscapes, street, our dogs.

Hoping some people can shine some light on the RP vs A6400, specifically:

- Is there a clear cut winner, if so why?


- Is the RP significantly closer to the 6400 with FW 1.4?

The A6100/A6400/A6600/A7RIV/A9/A9II's tracking AF is considered by many to be significantly better than any of their competition.

Even with 1.4? Does it bridge the gap? From my point of reference I have to compare to the A7iii without the object tracking that the 6400 has, so if the RP has gotten better and the gap is closer between the tracking on the A7iii and the RP, then it may be good enough.

- The 6400 has object tracking (which the A7iii lacks), how is object tracking with the RP comparatively (with the new firmware)?

- How is low light performance? Hoping to get some night shots around Hawaii

The RP should do better in this area, but lenses are a factor too.

Yes as I figured due to the small sensor.

- What starter lens(es) would you recommend (the RF 35mm is only $225 USD when purchased with the RP so I'd get that), but hoping for something with some long reach. For the 6400, not sure what would be good to start.

Based on what you're saying, I'd definitely recommend the A6400. It has the better AF, more affordable lenses to purchase, and options that would make it just as good in low-light as the RP. For example, if you are considering the Canon 35mm f/1.8 but want something longer, the Sigma 30mm f/1.4 or 56mm f/1.4 would be better focal lengths for you, and because of the larger aperture, could do better in low-light. You could also get the 18-135mm for versatility.

That being said, you still may lose out on the things you liked about the RP like how you preferred the ergonomics, user experience, and touchscreen.

The one thing that's in the back of my mind if going with the 6400 would be to potentially acquire FE lenses so I could upgrade to the A7iv later when it comes out, assuming I'm using the camera and there's a need to upgrade. So one lens I was looking at would be the 85mm f1.8, which would be roughly 127mm / 2.8 and should still produce night brokeh on the 6400.
