Pros: Sensor, configurability, ergonomics, AF, file.

Cons: Sufficient battery life, rolling shutter, 6 fps in uncompressed raw burst, mediocre ibis, overbuilt.

Opinion: The vastly improved menu and the ability to sew the configuration of the keys with a brush, make this machine more lovable than previous models. The ergonomics are there; both as a size of the grip and as a position and quality of the keys. The sensor is definitely valid both in sharpness and as a dynamic range. In real use, the noise at high iso is absolutely in line with other sony sensors and the difference with an A7III or an A7RIII is as imperceptible as it is negligible. The AF works very well and I was amazed by the reliability with the coupled 1.4x and 200-600. The files are excellent and have a recovery of lights and shadows up to expectations. The "chubby" car and battery life in my opinion has decreased from models such as the A7RIII or the A9II. The sony declares the camera at 10fps both in mechanical and electronic but there is a nice asterisk that is often not mentioned, or that in raw uncompressed frames per second drop to 6 with mechanical shutter. The fact above if we want is "aggravated" by a marked rolling shutter effect with electronic shutter. The stabilization in the car is mediocre and inferior to many of the other machine manufacturers. In my opinion these defects, which are in some cases simply software limits imposed by the parent company, make this machine overpriced by a few hundred euros. Net of all I must say that the machine gives excellent satisfaction and I am actually happy with the purchase.

Pros: Sharpness, autofocus performance, dynamic range, construction, customizable dials and buttons

Cons: Lack of focus bracketing, sensor that gets really dirty easily, 10fps as maximum burst

Opinion: Switched to Sony from Eos R5 because I was looking for a camera around 30Mp with stabilized sensor that Canon does not have in the catalog, and also for the wide range of lenses from Sony and third parties, I did not regret the passage. The A7IV holds its own against the R5 when it comes to focus tracking, even in low-light and difficult backlit situations. I had the opportunity to test it in birdlife, although I am a beginner, in moments of excitement when I had little time for shooting, I then realized that the fire always fell into the eye of the subject. The menu has improved but still difficult to understand for those coming from Canon, I had to follow various tutorials and set it finely, especially the part concerning the autofocus. Raw file really nice to work, compared to Canon loses a little bit on the shadows but gains as far as the highlights are concerned. Fantastic dynamic range and sharpness to sell, it's just what I was looking for in my portraits where I work the file 100%. There is no focus bracketing and this is a big flaw for a machine with so much technology, for extreme magnifications in macro you have to resort to a microslide. I then put among the defects the burst from 10fps, although you know at the time of purchase, and even if then a greater burst is not really necessary, since the camera costs almost € 3000, I find it at fault, especially compared to the competition. Last thing, I find myself having to blow the sensor after almost every output, it tends to get dirty really easily despite there is the protective curtain with the chamber off. Apart from these small defects that are known during the purchase, the A7IV is a great camera that allows you to get really quality photographs and to be comfortable in almost all situations (except in macro), today I would also buy it as a second camera body.

Pros: Excellent AF performance in both photos and videos. Real time touch tracking very convenient where there are no eyes. Current price. ISO holding in videos. At the same magnification the same iso seal of the A7 III. Battery life. Sensor with clever resolution, satisfies everyone. Complete video department.

Cons: List price. The workflow of raw files must be changed if you come from a previous generation sony. IBIS inferior to the competition.

Opinion: I immediately suggest disabling the automatic brightness of the viewfinder because it is very low, put instead at +1 or +2, it also gains the quality. If you come from A7 III I suggest you review your workflow to work on files, for example the camera raw settings are not good, the sharpness should be brought to zero or maximum 15 because it is already ultra sharp. Raising the sharpness here only does damage unlike the III. Another fundamental difference is that the IV works better on the highlights while the previous one works better on the shadows. This is a total hybrid machine, it is clear the direction that Sony wanted to take, the video department is very complete, the management of codecs, bitrate and color is identical to A7S III. Excellent autofocus both in video and in photos, it makes birdlife even if you are brocchi, good operating speed in general, excellent iso hold on video. Instead photo side, if these are observed on the monitor with 100% magnification you will notice about 0.5 - 0.7 stops of noise more than the A7 III, so if you are fixed with the ISO and look at the photos only on the monitor and only 100% better take the III or other machines with a 20/24 Mpixel sensor. While, as mentioned by some previously, at the same level of magnification of the photos, the noise is identical to the A7 III and gains in sharpness. And there is more margin in printing, where for the same print size the higher DPI density helps the A7 IV. For me excellent quality in general. Those who complain about the ISO tightness I think have not well understood that the signal-to-noise ratio is always the same, and a more resolute sensor is always preferable for the same sensor size and technology. Speech valid for any other brand, see Canon R6 and R5 for example. Ok let's move on, the viewfinder is good and fluid, as long as you put manual brightness, in the car it has a low brightness and indoors it is really a pity, put at +1 or +2 and that's fine. Decent monitor, a step back from Canon. Ergonomics for me good, very good, grips well, firmly, without uncomfortable angularity, I can not believe that someone is out with the ring finger, that you have the hand of polyphemus? For me, people now write the same things as always in repetition as a fashion. However, compared to Canon the shutter button does not fall ready on the index, but a small shift must be made, but even here I can not believe that people arrive in the evening with cramps. The dials instead fall more comfortable than Canon but are harder. Same thing menu, many controversies but it is only habit, it is linear, divided into macro areas, indexed and colored, everything is in its place, if you look for a function you find it where you expect it to be. Infinitely expanded customization of keys and functions. List price meaningless, evaluate well where you buy. As for the stabilizer, even this time Sony has failed to make the miracle and this is inferior to the competition, especially in videos, in photos is fine. In the videos there is the possibility of stabilizing in post production with a tool provided by sony, Catalyst, and the result is very good. PS: but those users below me who complain about everything about the machine, but bought it at random? A closed box? Without even holding it first in the store? Without inquiring about the features? Crop at 60 fps is written on the walls, before buying you have to know it, like unlit keys. You can not complain about a known feature passing it off as a defect, the defect is when a declared characteristic is not respected. Blessed are they who can afford to spend 2k at random, but then complaining does not seem correct to me.

Pros: Good file quality, operating speed. Maf very fast and precise. Ibis good side photo

Cons: Articulated display, iso seal, poor viewfinder resolution, ergonomics, value for money, non-performing ibis video side. Like all of them, it doesn't have backlit keys. Level does not specify. Menu, although improved in this model, is still mentally ill.

Opinion: I state that I only take pictures. Purchased in the worst period at the price of 2,650, I replaced a Canon r6 that had limits especially with regard to mgpx and the cost of the optics (excellent RF but cost a stone and there are few third-party optics). I found myself worse because the handle is really uncomfortable. The little finger and a little of the ring finger come out. Which unbalances the camera at the bottom especially by combining important optics. I partially solved with an L-plate of the smallrig. The Evf for a machine of that cost is really poor and even the adjustment of the diopters does not seem precise to me. In low light we are really at embarrassing levels. The internal level when I open the files from Lr is always starred. The totally articulated display for someone like me who only takes pictures, is uncomfortable. It forces you to do a lot more maneuvers. Being then very far from the optics makes the framing difficult (other than rangefinder). The zipper also does not seem to give a feeling of solidity. The high iso tightness is not good. Absolutely. And it is already perceived immediately above 2000. The sensor on the other hand, under normal conditions returns excellent images. The file has good workability but does not excel. The operating speed is remarkable, the burst is good but you have to use v90 cards, otherwise it decreases. Despite having two slots, one of which is hybrid for Cf Express type A (very expensive and that I did not buy), if one of the two is slower, even the fastest one adapts to the speed of the slowest ... In short, an all-round machine that does not excel in anything. Sony, a bit like all the others, has not yet guessed that there are things that an amateur photographer would appreciate. First of all, ergonomics. Holding these little bricks in your hand is uncomfortable. For someone who has medium-sized hands upwards, he is forced to mount supports for the little finger and part of the hand. If you don't, with a bit long shooting sessions you find yourself with wrist pain. The hand tends to compensate for the weight that unbalances the camera forward due to the weight of the optics. Second, the display... And here I draw a pitiful veil. According to these engineers we have all become videomakers... 6k, 8k... direction to Kubrick... and then we see everything from mobile phones... Plus with cropped sensor and a poor Ibis. I assume that videomakers or bloggers if anything will take the S series or other models of competitors, I do not understand the obstinacy for these hybrid machines and these gullwing displays. Ok there is the A7r... but it costs almost twice as much to have a thousand million megapixels often useless... Third thing... and light up the keys... they also had the Nokia 3310 a few decades ago ... For me a machine highly overrated compared to the cost. It's a good car, for heaven's sake. But it has big limitations. Limits that over the years have not improved, to the detriment of bursts, sniper focus, and millions of absolutely useless pixels. According to them we have all become directors, we all have 6k televisions, we print photos from billboards and we are all ornithologists... Sony has been good at creating a practically infinite optical park to which it has cleverly flanked the third-party optics (even if there are no pancakes and the restyling are all the prerogative of the G and GM series and the average cost is rising considerably). I would say that the extra value (for a photographer who does not make videos) of this brand is 90% for this reason. The optics of the GM series, especially the latest are remarkable. The camera project, in my opinion, is not following the evolution of optics. The level is only pure technology. So many numbers, but the substance is not in step with it. Ultimately for me it's a 7/10 machine

Pros: For my use, especially portability and AF.

Cons: As far as I'm concerned, ISO sealed.

Opinion: It's my second FF after a few years of changing aps-c between Fuji and Pentax and before arriving at the full format with Panasonic S5. Since I like (would like) to do street even in the evening-night, I hoped to find comfort regarding the tightness of the iso with this professional body, certainly wasted in my hands. As such an amateur pseudophotographer, I was definitely not disappointed, but still disappointed. It's true that I tend to crop some files, but with iso 2000 and sustained artificial light I did not expect to find that noise I find. Maybe I was used to "badly" with the Pentax KP that despite a smaller sensor, effortlessly held ISO 12800 and sometimes even beyond. I'm thinking of taking half a step back by exchanging the 7IV for a 7III.
