sony_a7cSony A7C

Pros: Portability, image quality, autofocus

Cons: Space for the little finger, stabilizer not particularly performing

Opinion: A fantastic gem! It's a very special machine, and you have to understand what you're going to buy. As dimensions it is really compact and lightweight, at the same time it conveys a good feeling of robustness. The ergonomics are not great, but it is acceptable. Personally I find it at the level of the other Sony with traditional form factor, much more uncomfortable than an EM1 and similar to the X-TX. The handle is fairly protruding, which facilitates grip, but the chamber is low and the little finger dances decidedly out. Obviously it is a trade-off with compactness, know it! It does not bother me particularly and with the use you make your hand. I find keys and rings well positioned and more than enough. Top image quality (about 24 mpx) and deadly autofocus! I find the stabilizer very little useful compared to the Olympus I had. Really capacious battery. Ultimately, it is a crazy travel companion that clutters very little, who says that there is not much difference with a traditional A7 body in my opinion is wrong. Weight and bulk compared to the A7R2 that I owned are significantly different in practical use. Speaking of viewfinder, it is small, but it is still fully usable. I find it beautiful coupled with small fixed as the 1.8 or the new zoom kit (great). It's still ok, for me, with zoom the size of the 28-75 Tamron. Beyond it becomes uncomfortable.

samyang_af35_f1-8feSamyang FE 35mm f/1.8 AF

Pros: Remarkable optical qualities in an affordable price; lightweight; blurred

Cons: "Cheap" feel to the touch, chromatic aberrations

Opinion: I've owned the lens for a year and I used it as the only lens glued to the car this summer. The lens is really light (but not very small) thanks to the plastic construction. On the other hand, the construction itself gives the idea of an "economic" object. For some it will be worth more, for others less, but the difference in tactile enjoyment between this and a lens like the Sony 55mm is remarkable. Small plus instead for the soft case included in the original equipment, good Samyang! The optical performance is really good, sharp enough for any application, it is also appreciated for an excellent blur. CCs are particularly noticeable in cases of strong backlit edges. They put themselves in place, but it can be annoying. Last clarification, the autofocus is generally excellent, but there are some small uncertainties in low light, where lenses such as 28mm and 55mm Sony do not have any. Ultimately, a great lens that becomes exceptional in relation to the price.

voigtlander_e40_f1-2Voigtlander 40mm f/1.2 Nokton

Pros: Unique yield, exaggerated opening, small and quite light

Cons: MF, but you already know

Opinion: Socket in VM version to use it on Sony with Techart. A crazy lens, even considering the middle adapter there are no solutions with the same aperture-size-cost ratio in Sony. Unique image rendering, to which some "defects" contribute including vignetting and not perfect sharpness at the edges to TA (I am interested in zero). Between 1.2 and f2 it returns very characteristic images, which to me communicate great immersion in the scene thanks to the relatively wide-angle focal length and the blurred that returns. In the center it is already very sharp at 1.2 and closed a few stops becomes a blade. But you do not take it for this, to be avoided if you are looking for extreme sharpness and total absence of aberrations. Autofocus chapter with Techart: it is not like a native lens (of course), but I find it definitely usable. As speed we are at the levels of the Canon entries of a few years ago, however fat that drips for an MF lens. A bit of hunting, but then hooks perciso. On the third generation it also gives me the eye af. It also works well continuously. I perceive a very slight lag between pressing the button and the actual shot that with native optics I do not have, but they are all things that for the use I do (portrait, street, events) count very little. If you like the focal length, which I find perfect as a handyman, you will not take it off from the machine anymore. A gem.

sony_rx100_ivSony RX100 IV

Pros: Compact, fast, a nice concentration of opportunities

Cons: If you know what you buy, nothing

Opinion: I arrived at this compact in my search path for a car that was in my pocket and I could always carry with me. I wanted to try the X100 series, making me (guilty) attract from the apsc, aesthetics, jpeg Fuji. Then I realized (guilty after) that it is heavy, bulky, definitely not in the pocket, except in a jacket. And I wanted to try the RX100 series, famous for being a "saponetta". Well, the machine is actually small and smooth, but does not claim to be wielded as a sLR. After a few days, it's comfortable. It's a concentration of technology and crazy mechanical solutions (it has a not bad scope and a flash!), while maintaining good easy access to the main functions. The lens is very good and bright, allowing you not to climb too easily with ISOs. In poorly lit and high iso environments the quality suffers a lot, but on the other hand we speak of 1 inch. Stabilization is effective and the machine is very responsive both as an ignition and as a focus. The battery lasts a little longer (not much less than the Fuji), but it is tiny and it is easy to bring a few more. With a mini easel and a pair of magnetic filters (ND and polarizer) I can carry in my pocket a system not bad on occasions where Mirrorless would not find space (eg: business trips, conferences). And the low iso quality is great, crazy if you think you put it in (almost) any pocket.

panasonic_leica12-60_f2-8-4oisPanasonic Leica DG 12-60mm f/2.8-4.0 ASPH OIS

Pros: Lightness, focal hike, construction

Cons: Nobody

Opinion: What about, excellent lens under all points of view and at a good price if taken from kits. It's great to have the focal lengths from 24 to 120 in such a small and qualitative package. The construction, like all the Panaleica is excellent and makes it very pleasant to use. Tropicalization Excellent. Sharpness and very good aberration correction, has a particular stamp that I love (also had the pana 12-60 smooth and JPG that come out of the EM1 II are immediately distinguished). Blurred just mentioned, given the format, but that makes me crazy. Only downside: You will want to try 8-18 and 100-400 (which are excellent) and 50-200 (which I have not tried yet). Compared to the Oly 12-40 loses a stop, but gains in flexibility and I find the yield softer and natural

panasonic_leica100-400oisPanasonic Leica 100-400mm f/4.0-6.3 ASPH OIS

Pros: Sharpness, weight, build quality

Cons: Maximum brightness

Opinion: Excellent lens in all respects. The optical quality is very high, with a slight loss to the maximum extent that in my case does not affect the usability. Very solid construction and very pleasant to the touch, fantastic to be able to quickly put and remove the bracket for the attachment to the tripod. In comparison to other M43 lenses is great, but if you think you have 800mm eq the size and weight are amazingly contained. Brightness does not excel, but falls into the category and price range. AF Performance (on EM-1 II) very good. A bit of a surprise even a very nice bokeh. If you do (AVI) Fauna with good light is spectacular, if you make itineraries in the woods or with low light coupled with M43 hurts a bit for the ISO.

panasonic_12-60oisPanasonic Lumix G Vario 12-60mm f/3.5-5.6 OIS

Pros: Cost, size, tropicalized

Cons: a dark hair

Opinion: Honest kit lens, performance much higher than you can imagine. I took it because it offers a very good focal range and it is weather sealed, feature for me important. From mistress of the fixed I use it in family and itinerant trips where I do not want to lose the shot and behaves excellently. High-level sharpness, fast focus, very effective stabilizer. It is obviously a bit dark, which on M43 is limiting, but this is known and helps to hold a low price. Taken used at €200, for use by handyman with good light I could not ask for better (I would have liked a similar lens when I was in Canon and in Fuji).

olympus_em5_iiOlympus OM-D E-M5 II

Pros: Lightweight, tropicalized, stabilizer, adjustable screen

Cons: Menu really very confusing

Opinion: Exceptional machine, photos with low iso remarkable and with more workable files of my old Canon, high ISO that suffer a bit ', but it is the necessary compromise if you want these dimensions. The car is really small and light, despite having a good grip that does not create too many problems until 12-40. Crazy stabilizer (with attention I get to shoot even at two seconds on wide angles) to not be able to do without. The screen maybe I would prefer it, but it's a minor detail. Very good electronic viewfinder and single prestant autofocus (it only takes a moment of effort sometimes in low light). Finally, as a system the m43 offers a very wide and multifaceted optical park. In conclusion: highly recommended, especially at the price you can find today if you are looking for portability and quality!

canon_600dCanon 600D

Pros: Swivel screen, good entry-level, compactness

Cons: Big big, third-degree missing, look a bit small

Opinion: Great start-up or back-up machine: the body is small, but well-accessible, the quality, especially low, is definitely high. Great for the swing screen and big dedicated keys, you can not use third parties (with magic lantern yes). I use it in my opinion as long as 1600, with a bit of noise, in addition, if in low light, it becomes unmanageable. Recommended as a body for those who start now, given the prices of the used, but also as a "battle" body to be fitted with another machine.

fujifilm_xt1Fujifilm X-T1

Pros: Great compromise lightness-quality, optical park, used price

Cons: Autofocus not really lightning

Opinion: I bought this used car, 1 year ago, from happy owner of 5D and 70D. The feeling is great, the plenty of keys and rings makes the shot even more enjoyable. The image quality is very good: as colors is better than Canon, in my opinion, good dynamic range, good ISO resistance. I took it as a travel car and kept it in the bag together with goals like 18, 27, 35 Fuji becomes really cumbersome. After 6 months of affiliation I sold the 80D, which I used little, now alternating with satisfaction at 5D. Compared to the 70D I find the image quality slightly higher (not much difference even from the 5D first series), convenience and enjoyment of use are superior. You definitely lose the AF side: do not expect miracles of the series "equal to the reflexes", but not spar on uselessness. It works well on single subjects, very precise though somewhat slower than the 70D of day, it makes a little more effort at night;You will never miss any shots due to the AF if you do not do avifauna.rn Last note about the batteries: with a few things (no pre af, no light af if they do not), and if you are not compulsive of the shot, Is to worry.

fujifilm_16_f1-4rFujifilm XF 16mm f/1.4 R WR

Pros: Sharpness, colors, overall quality, autofocus

Cons: A bit bigger than the Fuji machine bodies

Opinion: Fantastic goal, perfection made wide-angle in Fuji home. Phenomenal constructive quality, optical perfection: no aberrations even at 1.4, where the bokeh in close proximity is also very pleasant, stunning sharpness at the center and very good at edges. I think it's equivalent (if not even slightly better as sharpness) at 24 1.4 L II on Canon, I had for 4 years. The only "defect", like the brother Canon, has coma up to 2.8. Autofocus (on XT1) is very quick and accurate. I used it a year with great satisfaction, I'm trying to sell it only because of its not compact size, a bit against mirror mirroring philosophy. If the value was a shorter moment I could not separate it.

canon_efs24stmCanon EF-S 24mm f/2.8 STM

Pros: Lightness of field, angle quality

Cons: the focus ring without limit switches and references, bad to use in manual

Opinion: phenomenal optics: the attacks on the camera body, you forget to have it and not coming off the most. I use it often as a fixed-rounder on vacation and returns perfect photos without being in the least in the way. The use of 70D and coupled it becomes extremely simple to handle and fit in a backpack. Together with longer perspective (usually trip with this and fifty), allows you to deal with any situation lightly estrema.rnE 'clear already at 2.8, insert a slight vignetting pleasant and returns a "perspective in the scene" that I love. Consider now the purchase because then the other targets will use them pochissimo.rn
