Pros: Exceptional sensor, produces both RAW and JPG files of the highest quality; compact size, light and extremely handy even for those with large hands; spectacular manual focus (focus peack); excellent software, able to give adequate answers to every situation (the menu is very complete, without being exaggeratedly complex); Excellent buttons and auxiliary wheels, widely customizable....

Cons: SLOW AF; sensor that gets dirty with great ease; battery life; very loud shot (but with a nice sound!) ...

Opinion: It is my first FF and I must say that it has fully met my needs as a photoamateur: the quality of the files is exceptional, especially in good light conditions and good is the "hold" to noise up to 6400 ISO. The dynamic range and quality of colors are excellent. In light of the purchase price - new to just over 700 euros - it certainly constitutes an excellent product, especially when used, by virtue of its lightness, as a travel camera. In my case, after trying several goals, I found myself very well with the Zeiss 24-70 mm f/4, whose excellent stabilization compensates for the one absent in the machine body, of which I do not meet all the defects that are attributed to it, instead appreciating the lightness, sharpness and overall image quality, in the face of little criticality... and at an attractive price! In summary, the a7 has a compact and sufficiently robust body, with a decent tropicalization (I used it in adverse climatic conditions, but did not suffer), the image quality is always excellent; It has a good electronic viewfinder and you appreciate the practicality of a tilting and rather robust display. The auxiliary keys are well made and allow an excellent possibility for customization. Even if it is not a video amateur, I appreciate the quality of the videos produced (in this case, the failure to stabilize the machine body is most affected) and, all in all, the dislocation of the video activation button is not so uncomfortable. Great software and camera features, extremely evolved, as is great the ability to connect, including the fast and practical built-in Wi-Fi. Among the flaws, the main, in my opinion, is the autofocus, sometimes slow and inaccurate not only in poor light conditions, and the rather reduced battery life, which can only be recharged by the camera (but there are excellent third-party products that at a low cost to this problem).) It's a pity that the Sony lens fleet, which with 2019 can finally be said to have been completed, is still quite expensive, while boasting excellent products at a low price (such as the excellent 85 mm f/1.8); Fortunately there are excellent optics of other manufacturers, which, at acceptable cost, fill this deficiency (exceptional the combined with the 14 mm f/2.8 AF of Samyang!). Finally, I find that the menu is not as disastrous as it reads - but perhaps in this I am benefited from the fact that I have used for many years a Sony bridge that, basically, had the same menu as the A7. In conclusion, I can say that who wants a low-cost FF, light and compact, but capable of giving high - very high! - results for portraiture, landscapes, travel, street (but not suitable for naturalistic or sports photography, especially in poor light condition), the A7, still in production, is a great deal!

Pros: Flexibility and ideal solution for those who use vintage optics. Great FF 24Mp sensor, overall build quality, focus peaking.

Cons: Mainly the monstrously short life of the batteries. Plastic-metal attack, sensor that I find easy to get dirty. Other minors, or more subjective: gripist not perfect for the small size of the body (but on the other point of view this is an element in favor!), ergonomics with wheel controls/buttons partly not very intuitive, like the menu, at least for me. Noisy shutter button.

Opinion: Taken at the end of 2017 with a nice occasion in the used, she donated a second youth to the vintage kits of the house, mainly Canon FD and Pentax A and F extended lately to Nikon, probably for the renewed pleasure of making photography that gave me back in time recent A7. I started about forty years ago with MF lenses, so the fact that I can't use AF is not unwelcome to me, so I'm fond of this fullframe mirrorless. Today, however, I would opt for an A7II because of the stabilizer but at the time I was not aware of the various improvements in the mark II model. However for the few shots per year I also do the basic model i'm fine with. Stabilization is a plus that could obviously be useful to me; there is to say that in macro I often use the flash and bring tripods, of which I have many choices, does not give me too much boredom. And then I prefer to invest in more or less dated, but quality goals (also because Sony optics would be and are frankly unapproachable for their costs!). The Sony 24 Mp sensor churns out JPG vouchers with beautiful color yields and even better RAW files, but it seems to me that it gets dirty easily. Up to 3200 ISO is still usable, from 4000 the noise begins to appear noticeable. In the absence of Sony autofocus lenses, focus peaking is a great help for images where accuracy in focus is more critical and generally for those with vision problems. The electronic viewfinder satisfies me. A little difficult to find Sony compatible accessories in the used, but looking you succeed. I do not like the fast discharge of the battery, already highlighted by many: something so extreme had never happened to me! And Sony could also add an external charger to the packaging without going bust. Rating: 8.5

Pros: Compact, light, sensor, price

Cons: So-so ergonomics, switch Monitor-automatic EVF, unreliable autofocus, sensor flare, very noisy shutter

Opinion: It is my first photographic stain "important" and I have therefore no references to make comparisons. However, after 1 year and a half of intensive use, I can definitely say that I have made a clear idea of the merits and flaws of this Sony. Starting from the good things, I would definitely cite the sensor from which you can get beautiful RAW files with good dynamic range and so much information to work in post production. For an amateur level is also a sensor too demanding that requires excellent lenses to be exploited. In This sense the zoom kit I used for about 4 months couldn't absolutely fix it properly. Coming to the machine body, it is small and light, more compact than the later models (A7II and A7III). Also for this reason the ergonomics is not great (but you get used to it). Good and discreetly durable construction. What I do not like: the continuous autofocus (unreliable) not suitable for chasing fast subjects. Automatic Switch Monitor/EVF: I often get closer to the camera to the body to shoot with the screen oriented upwards, but about twenty inches from the chest the machine passes from the monitor to the EVF. This is very annoying, it would suffice to recognize that the screen was extracted to disable the passage to EVF and avoid the problem. Shooting noise: really very loud! Flare sensor: Effect that emerges in the presence of intense lights and strong contrast (for example the lampposts in the night photo) creating many halos visible around the light sources. Out of curiosity I've been informed and seems to be generated by the sensor lining on this first Sony A7 series. For me it is not a big problem, but in short here not very well... By pulling the sums this Sony has given me great satisfactions so I will continue to use it and exploit it until it is its limits (and not mine) to make me lean for a change. Rated 8.5

Pros: Compactness and excellent sensor

Cons: Build quality not at the top

Opinion: I am attracted by this camera, especially by the ratio of quality, price... but to the engineers as it occurred to him to make the attack consisting of two materials, metal and plastic? The bayonet could not do it completely metallic? Steps for the machine body in part in magnesium and partly in plastic, but in the bayonet you are mistaken, the plastic part can loosen

Pros: Size, FF sensor output, MAF ease with manual optics, convenience of WiFi, functions and customization, possibility to load it via USB

Cons: Optical cost, battery life, absence of useful functions that can be purchased only for a fee

Opinion: I wanted it as a secondary body but FF, after the little harmony with a Fuji mirrorless APS-C. I rediscovered the pleasure of always taking her back in every moment of the day, without losing any chance. I can easily and with great yields use manual optics to rediscover the taste of hand-focing, which with the SLR FF and APS-C is impossible. And after years of Canon I'm thinking of totally switching to Sony with all the professional outfit, but we'll see. Very convenient to be able to frame and shoot via smartphone, in the street environment is a godsend. I can fast-forward even in motion without losing the shot. This is not practical and usable professionally, but as a second body has more merits than flaws. Especially then find it at €450 is worth.
