fujifilm_xt30_iiFujifilm X-T30 II

Pros: Small and light but very performing, low price.

Cons: I can't say.

Opinion: An APS-C sensor that produces respectable frames and that has nothing to envy to an FF, inside a compact and light body that however has all the necessary functions for landscape, street, travel. Combined with a suitable lens, you always carry it with you without feeling its weight. I'm hardly using the Canon 6D mark II anymore. Why should I? Really I am very satisfied to have this little Fuji.

fujifilm_xc50-230ois_iiFujifilm XC 50-230mm f/4.5-6.7 OIS II

Pros: Lightweight, low price, compact, decent sharpness, stabilized.

Cons: Nothing.

Opinion: It is a zoom to always carry in your bag given the very small size and weight. Of course it cannot be compared to lenses of the same higher range focal length, but for the use for which it was designed it is a very valid lens. The stabilization works pretty well and the autofocus doesn't miss a beat, at least in my short experience of a month. I find it great for those situations in which you either have a 300 mm equivalent or do not take the picture; In fact I bought it for this reason in addition to the fact that I could use it for landscapes.

venus_laowa_cf10_f4Venus Laowa CF 10mm f/4

Pros: Very small weight and size, metal construction, fairly good sharpness, has no distortion, macro possibilities, price.

Cons: Manual lens that does not communicate with the camera, vignetting (but for a 10mm with this size, one should expect it).

Opinion: A lens with very low weight and dimensions and not bad performance. Apart from the focus peaking that quickly solves any MAF problem with fuji, I calculated the optimal focus at infinity and the one related to the hyperfocal at the various apertures. Once this was done, I could see that this 10mm is sharp enough for the use for which it was designed. It should also be added that this small lens churns out undistorted images. My personal experience with this lens has led me to conclude that the best aperture for landscapes or freehand street is f8 at hyperfocal distance or f5.6 with focus peaking, while the best aperture on tripod is f11 or f16 (f22 almost unusable) at hyperfocal distance. The hyperfocal distance on my model is around 1 meter for f8, f11 and f16. A f4 usable for macro or selective focus. In conclusion, it is a tiny glass and metal lens, a "cookie" that churns out sufficiently sharp images after taking a little 'hand. It is worth its $299 bought directly at VenusLaowa.

fujifilm_xc15-45oisFujifilm XC 15-45mm f/3.5-5.6 OIS PZ

Pros: Lightweight, compact, economical, excellent value for money, very good sharpness for its class.

Cons: Low light, (but one does not buy it for brightness). It must be known to take full advantage of it.

Opinion: The lens came in kit with the Fuji X-T200 that I purchased as a complement to the Canon 6D II kit. At first I was at the point of sending back both the lens and the camera several times. But rereading the manual and also some fuji posts in this forum, in the end I am very satisfied with this small but performing lens. I will briefly summarize the problems encountered. Shooting in abundant light conditions with the image stabilizer enabled I obtained unacceptable images in terms of sharpness, thinking that it was the fault of the lens; instead I discovered later that with the X-T200 (but it seems that it is the rule with Fuji mirrorless in general) you should not use the IS with very short times, like 1/500-1/1000 or shorter, especially with the electronic shutter. So I learned to disable the IS of the chamber in normal or abundant light conditions. The other problem was that I couldn't get decently sharp images at 15mm focal length at the top right of the frame, in subjects close to infinity or otherwise distant. Increasing the focal length the problem disappeared, but at 15 mm (22.5mm equivalent, which I use a lot) and only for subjects close to infinity, so especially in landscapes, the image appeared annoyingly devoid of sharpness in the upper right area from 3/4 from the center to the edges; a nice hassle. Well, in the end I discovered the cause: by making the focus in AF with the center point, the lens fails to focus endlessly at the edges, as if the focal plane were curved. But especially in the upper right corner (at least in my model) evidently that part of the frame suffers more than other areas this out of focus. So I found the solution: using manual focus with focus peaking combined with the depth of field bar, the sharpness improved significantly; decently sharp images over the entire frame, compatibly with this class of lens (at extreme angles you can not expect the sharpness of a 1500 € lens). For 15mm landscapes I'm fine with using manual focus peaking, precise and fast, so I decided to keep the lens. To conclude, it is a rather sharp lens that does not disfigure in comparison with more quoted lenses that I have in my Canon FF kit.

fujifilm_xt200Fujifilm X-T200

Pros: APS-C 24 Mp small and lightweight, excellent file quality, excellent dynamic range, battery life, numerous functions, electronic shutter.

Cons: Hot pixels on long exposures (but the solution exists).

Opinion: I bought this mirrorless after giving away the Panasonic GX80 which was perfect in everything except the micro 4/3 sensor; too small for one who is used to FF. The purpose for buying the Fujifilm X-T200 was a small, light and performing mirrorless, not too expensive, which complements my Canon 6D mark II kit but does not make me feel too much the difference with the FF. I have owned it for a few weeks but I have already taken several hundred photos testing the limits of this little jewel that has not disappointed me at all. I can no longer leave the house without taking it with me; 500 grams between camera and lens fit comfortably into the pouch. As for image quality and color rendering does not make you feel all that difference with the 6D, indeed I struggle to understand that I am working on an APS-C when I open a file in Camera Raw. The 15-45 lens that comes in kit then is perfect for my purposes, in fact it corresponds to a 22.5-67.5, a respectable wide angle with the possibility of closing a little in need, also it is really very sharp. As for the sensor, as a canonist I was amazed by the possibility of recovering up to 4 stops on the shadows, which is not even thinkable with Canon! Then the personalized menu allowed me to assign my favorite functions to the buttons and wheels, combined with the electronic viewfinder from which I can control everything without having to open the viewer and consequently having to bring my glasses with me (in the viewfinder I have the adjustment of the diopters), making its use quick and easy. I found only as a defect the appearance of numerous hot pixels (white dots) with exposures on tripod over 10 seconds, but then I found a way to eliminate them by means of the dark frame and the PP.

sigma_50_f1-4artSigma 50mm f/1.4 DG HSM Art

Pros: Excellent sharpness, price.

Cons: Sometimes the fire is wrong with the 6D.

Opinion: This is a sharp knife that is therefore "handled with due care". The sharpness is excellent from the maximum aperture and if this is the most important feature to evaluate a lens, the "Sigma 50mm f1.4 Art" has it. Moreover, I did not see aberrations clearly visible. Of the best quality I've ever had. RnThe Canon 6D is not the ideal reflex coupled with the entire "sigma art" series, because of the many issues discussed on the forum many times, anyway even if I miss a few clicks, I can Get a 70-80% focus on portraits. And if one considers that with such a high-quality lens, a few millimeters of open-aperture fire blur emerges clearly, this percentage is not so bad. Rnrn

sigma_20_f1-4artSigma 20mm f/1.4 DG HSM Art

Pros: Brightness for a 20mm, sharpness, low chromatic aberration, build quality, autofocus, minimum focusing distance, price.

Cons: Weight.

Opinion: I bought this lens mainly for photos the night sky as a bright 20mm is the perfect focus for this genre, but a 20mm f1.4 is a goal that must absolutely avere.rnFatte the first tests in the night sky I noticed a blurring problem the TA in the central area, so I sent the lens care. After a few days they sent me back and told me that it was only a firmware upgrade problem: redo the tests in the sky and I can see that the central defocus was risolto.rnLe stellar images are of excellent quality already at TA in much of the frame if you exclude the extreme edges, and comparing them with those of the Canon 24mm f1.4 L II that I gave away to take the Sigma 20mm f1.4 art, the latter clearly wins despite having a field of about ten degrees higher and price around the meta'.rnMa this goal can not be limited only to the astronomical photos, in fact for general use by day or in poor conditions freehand light I could appreciate both the SFOCato selective in TA (also because of its minimum focusing distance) and at smaller apertures. rnih anyway always stands out its excellent sharpness and also the autofocus works in a manner acceptable in conjunction with my 6D.rnPer end, a lens of nearly a kilo but that 'does not make you feel the weight when you carry with you. rnrnrn

sigma_20_f1-8Sigma 20mm f/1.8 EX DG

Pros: 20mm, f1.8, minimum focusing distance of 20 cm.

Cons: Sharpen the edges unacceptable and generally rather poor.

Opinion: I was looking for a bright wide-angle to photograph the night sky. The focal length of 20 mm is ideal for this type of photo, and in addition the opening of f1.8 is very good, so on paper the Sigma 20mm f1.8 was exactly what I needed, so I decided to buy it . rnHo made several pictures with this lens and I must say that in the end are not so bad, but if one goes to look at the details out of the middle of the field, will be blurred and lack nitidezza.rnPer conclude, especially in the photo to the starry sky, you note particularly the stars on the sideline for the aberrations and the lack of sharpness. rnSi appreciate this lens the minimum focus distance (20 cm) and brightness, for those who like to disconnect the subject in the foreground from the background or vice versa by means of the selective focus. rnrnSarebbe Sigma desirable to revise this view and it would redraw the diagram, correcting aberrations and improving the resolution, since a 20 mm f1.8 for FF does not exist on the market and is ideal for photos at the sky notturno.rnrn

canon_15_fisheyeCanon EF 15mm f/2.8 Fisheye

Pros: Good quality / price ratio, sharpness, brightness.

Cons: Building a little 'leggerina, cap that can be easily removed when storing it in the bag.

Opinion: Being a diagonal fisheye not straight lines you can expect from this lens, in fact distorts enough and one uses it for that if he comprato.rnMolto clear since full aperture is also useful for photos at the night sky, such as the Via Milky Way or the stars cadenti.rnPersonalmente I use it a little but on those occasions may be a lens irreplaceable.

canon_24-105Canon EF 24-105mm f/4 L IS USM

Pros: A lens with which you can do almost anything, lightweight, very sharp, excellent IS and tropical conditions, accurate autofocus, large focal length from wide angle to hike drape, in short, the hills on your SLR and not take it off anymore.

Cons:

Opinion: Lens with great clarity at all focal lengths and since the maximum aperture. Have attached to the FF camera means having a very wide range of focal lengths from wide-angle to the small canvases and then be able to exploit it for landscapes, portraits, reportage, travel, etc.. Has distortion at 24mm but with the modern SW corrects itself without any problems so 'as the chromatic aberration is not excessive. The excellent IS allows you to shoot handheld at 1/8 shutter speed at maximum focal length (105 mm) with excellent results. rnL'unica sin apart from the flare that I do not dramatic, in my opinion is that being f4 limits you very much the focus.

canon_24_f1-4_v2Canon EF 24mm f/1.4 L II USM

Pros: Brightness, sharpness, construction.

Cons: No.

Opinion: I bought this lens mainly to take pictures of the Milky Way, but it would be a shame to limit its use only to the sky notturno.rnSi is an excellent lens that produces razor-sharp clarity to the edges from f2.8, but you can safely use already by f1.8, while the maximum opening is a bit 'soft. RNA part of the photo to the night sky is a multi-purpose lens that can be used in any low light conditions without flash and freehand. The blur is great in contrast to the great sharpness of the lens and the excellent precision autofocus. rn
