Has anyone traded up to the Sony a7RM4 from the Sony a7RM3?  If so, what is your pros and cons of doing so? 

Any insight in:  IQ, ergonomics, file/data handling & buffering, and focus speed and accuracy, low-light and high-ISO noise

Thank you in advance!!

Hi,I did do it and in a nutshell here are my pros and cons :

Pros :

- IQ is outstanding and better than the A7RIII . Let's be clear : the A7RIII is quite a good camera, but the MKIV gives even more detailed pictures. It is really impressive.

- The pixelshift is quite good and give outstanding results under good conditions.

- Focus speed and accuracy is excellent and eye / face detection works extremely well. 

- The IBIS is excellent : I was fearing some issues with hand held shoots, but it works quite well. I am impressed.

- The ergonomics are better on the A7RIV : I like very much the new grip, the new buttons, SD cards slot and the quality of the viewfinder.

 

Cons :

- Noise is coming earlier when increasing your ISO,  which by the way is not a surprise : the pixels are smaller. Same thing for diffraction. The 61 MP sensor is also more sensitive to shake than the 42 MP one. But so far, I did not find all that as a real issue.

- Linked to the comment above, you need to pair your 61 MP sensor with the very best lenses : it has a cost if you are not already equiped with a top class gear. 

- The use of SDXC class II cards is highly recommended if you want a good data transfer. And a good PC / laptop is welcome. I have no issue with mine using Capture One, but it is a high end gamer one chosen on purpose. 

- If you don't go beyond the A3 format printing or don't need to crop significantly, the 61 MP may be of little use.

- If you sell your A7RIII and buy the A7RIV, it is not a cheap switch.

 

All in all, do not be misleaded by the "cons" I have absolutely no regrets for having done the switch. The A7RIV has such a great potential !

I'm seriously considering being on the receiving end of such a deal. Not trading in my a9, but rather buying a used a7riii as a 2nd body ...  😎

I took the plunge!  I await arrival...

I gave my A7RIIIs to my daughters who are thrilled and I have upgraded to the A7RIVs, love them, and while the the IIIs were great the IVs are just a better camera overall, the ergonomics are much better the IQ is outstanding, the small increase in noise is slight and for me a non issue. Love them but as said earlier here for some the 61 mp  maybe overkill. The A7RIII is still an outstanding camera.

Yes, the poster hit it.

Ergonomics are better, but an firmware update in menu organizing would be welcome. Especially the back button AF is a pleasure.

You need an superfast Calls II card, mine V60 struggled with video in 4k, so an "V90"  is needed IMO.

You enhance image quality by using "the best" lenses you can get. Not always GM lenses are needed. I´ve tried some lenses  from different manufactuerer, i leaned from  Sonyfriendboys in the last few weeks. My personal findigs in practical usage for landscape and people photography are:

The new Tamron 17-28 III is almost as good as the 16-35GM if you do not need the missing mm in local lenght

Also my 24-105 G compares well with the 24-70 GM

The 100-400mm is optically better than my 200-600, but worser, if I use the 1.4x extender with the 100-400. Also AF gets worser witht he converter added.

The 70-200 4 is as good as the GM version. Only the AF works a little bit faster

My heavy 50mm sigma art lens is still ahead of the Sony model

And the 1.8 85mm compares well to the GM and the Zeiss Batis.

With the 135mm GM I just took some shots, but I´m surprised that it beats the sigma just in AF perfomance, but the shots look equal.

I will look forward on the 65mm Voigtlander macro, a friend ordered it last week.

And my brand new order, the 24mm GM, I´m waiting for.

 

Who is willed to share lens experience with the A7 R IV ? I would like to read...

You are right, not only the GM lenses can be used with the A7RIV, and we see more and more good E mount lenses coming from other brands such as Sigma or Tamron. 

A few tests with my gear and some family/friends lenses with the A7RIV body :

- I did own the 35 mm Zeiss Loxia and sold it back : too soft with 61MP. I have now the Sony 35 mm F1.8 and it works well. It is may be the best 35 mm prime choice for the RIV body. I tried the Sigma 35 F1.2 which is definitely a high quality lens,  faster and a little sharper than the Sony F1.8 but much too big and heavy to carry in my bag.

- My 24 GM f1.4 gives very good results . It is in my opinion one of the best GM lenses.

- My 50 mm Zeiss Loxia is quite good. I did not expect that and it is a good surprise. I also tested my daughter's Sony 55 mm F1.8 : it is good but not as it is with her A7RII.

Despite the large number of 50 mm lense choices  available on the market, I am still waiting for a very good (not heavy and bulky) one to pair with the A7R IV. 

- The 110 mm Macro Voigtlander, which by the way is one of the sharpest lens (all along the aperture range) I ever owned, behave very well with the R IV.

- The 135 GM behaves also very well. Paired with the R IV, it provides fabulous portrait pictures.

- I do agrre with you for the 100-400 GM. I did not see any issue so far (without the 1.4 converter I also own) except that noise coming earlier with the 61MP sensor, you need good light conditions to shoot clean pictures.

- My daughter's 24 105 Sony seems to behave well. The only drawback is distortion which can be corrected of course but at a price of lower IQ.

- I also tried the 28 75 Tamron from one of my friends and it was surprisingly good : not perfect of course but usable if you are not too demandind for corners sharpness. For family or events pictures, it can be an unexpensive all around lens choice. Tamron seems to do a great job with good quality lenses at affordable prices ( not like the GM lenses).

      Hi, wonder if anyone is familiar with this, A7Riii has 42mp sensor while A7iii is 24mp, what effect does pixel size have on low light video, besides the obvious max ISO limit, thank you

      Hi. Newbie hobbyist who started last June. Does anybody know what would cause the "bullseye" in the center of this shot? I shot this using an a7r iii with FE 2.8/24-70 GM lens. My settings were 15 sec, f/4, iso 800. Also, I didn't see the bullseye on shots at 5 sec, f/4, iso 800. I had Long Exposure NR off for both shots. Thanks.

      I currently own an A99. I have some investment in o A mount lenses, but not too much to the point where it'd be hard to justify a switch to the E mount. I like my A99. However, I am interested in taking advantage of some potential savings while I can still get some money for my A99. I am a scuba diver and one thing I have been frustrated with is the ability to get an underwater housing for my A99. It seems that most of the underwater housing companies have moved on to the E mount cameras. I am currently a hobbyist whose done some professional work. I am planning to take on more professional work. My focus is will be on architectural, commercial, and product primarily. I may also do some portrait photography. I will also use my gear in underwater situations. That will be more of a hobby (vacations, etc.). I love the idea of going all-in and switching to the A9, however, I can't justify the spend for that. I do like the idea of taking advantage of some savings on the Sony A7R II that are going on now. However, I understand there are several limitations with that camera. So, then I come to the A7RIII versus just upgrading to the A99II (I fear the lack of an underwater housing here). Given the choice between the A7RII and the A7RIII, which would you choose? Or would you bite the bullet and just go for the A9? I am thinking about the long term. I'd like to invest in a system that I'll use for the next 15 - 25 years.

    • Pieter,   You answer your own question why: " absolute best image quality despite bigger file size and more noise on pixel level."   Given my experience with 35mm, med and large format I know what increased resolution looks like even with much smaller prints of 8x10 and 11x14. In this case its certainly not marketing crap. Its a real world improvement. If you are using the kit zoom then perhaps there is not much more to resolve but again I'm using quality prime lenses and I know
    • Hello you all! I'm trying to make an automatic turntable for object 3D scanning (photogrammetry). I use this connector to interact with camera multiport: Sony pinout on Multiport For now it's working well, I use some custom electronics to trigger the shutter connecting trigger pin to GND. But it only work with the self-timer activated. It makes my scan process really slow then (even with the 2sec selftimer) Do you know a way to use directly the trigger pin (I mean,
    • I was also going to mention the A7x's. 24mp is absolutely fine for me, image quality is great and it's more than big enough for any print I would ever want to do. Until then, I don't see a need for more. For what it's worth, I previously owned a Pentax K1 (36mp). It was nice to have that additional crop-ability but it was entirely unnecessary for every scenario I would use my photographs (currently).
    • Hi, many forums and the "pros" once were certain that the star eater issue makes the Sony A7 Series unusable for astrophotography but I always had good results with my Sony A7rII. So I recently went ahead and had it astromodified. The thick IR-Block Filterglas was replaced with a thin Baader substitute that lets IR Light down to the h-alpha line and the sII line through to the sensor with high transmission. The results can be seen in detail on my google drive link here: https://drive.g
    • Honestly, why do you need more MP? 24 MP is plenty for any kind of print you may ever want to make if you factor in optimal viewing angle. All these bells and whistles you speak of result in a vastly better image than just boosting the MP-count would (better AF and subject tracking, better low light ISO-performance, etc). Higher MP is just marketing crap unless you plan to heavily crop or print billboard size and stand with your nose against the canvas. For good reason the A7x you refer to
