Sony RX10 Mk III just as good?

Hi everybody, new on the forum and also new to the Sony world. I always owned Canons but at one stage I've find it too heavy to carry so many lenses so it was sold and purchased consequently my first RX10, then the Mk II and now the MkIII and no long ago an A7RII. Here is my question, Love the RX's but I find them very restricting (small sensor) but I am hoping somebody out there will tell me the new Mk IV is way better or should I purchase more new lenses for my A7RII? Kind regards Clem

First of all, welcome to Dyxum !

The 1" sensor of the RX10-series obvioulsy does not match performance of the A7-series FF sensors. Comparison with your A7Rii will have made that clear.

Given the 4th generation of RX10 again has this 1" sensor, image quality is pretty much the same (and performs very well, surely sufficient for most purposes i.m.o.).

Main improvements over the RX10 III are AF, meeting requirements for sports and action photography, touch screen, improved eye-AF and subject locking, and new menu structure.
I had version III with me on vacation during summer last year, and purchased version IV for the vacation trip this year. I am pleased with the results obtained with either version :-). Given their wide range, both allowed me to keep the 70-200/4 on the A7Rii most of the time.
The A6300 with 10-18/4 was the third combination at hand. Occassinally, A6300 with 16-70/4 was the only set used (when we wanted to keep it really compact).

That being said, since you already have version III and without knowing which other lenses you have,I would make sure I have the lenses I like for the A7RII before getting an RX10 IV.

First of all, thank you all for the warm welcome and I am amazed how people for all different parts of the world share knowledge. I know there are talks of a new RX10Mk V but nothing about features and improvements etc. Currently I own 2 lenses. Sony 16-35 f4 and 24-70 f2.8 GM and if I wanted more reach I guess it will depend on what photography I want to do hmm... I think landscape photography will be ok with my Sony A7RII and the current lenses, with the RX10III I could get some Wildlife shots ( in a bright sunny day) but I think RX10IV would be better for this. Your thoughts? Thanks again to you all. Clem   

Thank you Almazar80, I must say full frame is and always will be much better but "the lenses , the weight!" I think you are pretty much "on the money" the thing is if I am not planning to enlarge to huge prints and I am able to deal with these restrictions the outcome is very nice still. being honest with you I feel a little guilty for being kind of lazy and surrender to a lower quality for the sake of convenience. I hope the new RX10Mk V will bring the answer but is only a hope I know. I think I will shortly sell the III get the IV and this move will be the right thing to do in the right direction. what do you think? Thank you for taking the time to help. Kind regards Clem

Agree with you Paul, the 100-400 could be a good investment but perhaps I will explore Landscape before getting in to birds and wild life photography and having said this what could be a good entry level lens to go with my A7RII? Would it matter if it is manual or not? Thank you for taking the time. Clem

I don't think full frame is always better. I don't like the weight of the camera and lenses, but I love twiddling with DOF and full frame, coupled with wide apertures, allow me to do that. The RX10IV is a revelation. It has allowed me to go out more and experiment more with the kind of pictures that I take (near macros with a 600mm perspective is quite different from a 90mm macro lens on a full frame). I think it's great that there are so many tools available for people to use now. Though I must admit that the RX10 is my most often used camera. I want to get the 200-600 zoom so that may again change the camera use mix. The thing is, just take pictures with what you have. Sometimes, what you envision limits what you can actually do.

If it is about the AF and reach, I do think the RX 10 IV looks like a solid choice. The V probably will probably have the new AF system, so, even better. I think both the IV and V are solid choices - if the price difference is worth it we'll see after the V is announced

The 28mm nice cheapish option but not the best lens in the Sony line up. I was a bit disappointed with it because I expected too much of it. But still, good price performance balance. It uses distortion correction and it seems it is wider to allow that correction. Something I would not worry too much about.
