The following opinions have been automatically translated with Microsoft Translator. | Canon RF 16mm f/2.8 STM Pros: Ultra-compact size, featherweight, widely satisfactory optical performance (shooting in JPEG with all in-camera corrections activated) with effective distortion correction, beautiful colors, very short focusing distance, very advantageous quality/price ratio Cons: The autofocus has focus hunting phenomena and is slightly noisy, there is no internal MAF, edges a bit soft to TA Opinion: Only very few shots taken so far, so I report my first impressions. The build quality is practically the same as the RF 35 mm macro, all plastic but very well made. I confirm the note of "Chebeltempo" about the graft on the camera body, actually harder than the other lenses I own; It seems to be a fact of mechanical tolerance with respect to the bayonet flange. The negligible weight makes it a perfect travel companion. The ring on the body that manages the customized functions has a continuous operation and not jerky. Super-wide-angle focal length in my opinion optimal, it is not excessively pushed as a 12 or a 14 mm, and at the same time gives a nice breath more than a 20 and a 24 for all those circumstances, for example indoors, where space is limited and you need a wide angle of view to make everything that interests you stay in the frame. Autofocus: I expected something more, despite having read from the reviews that it is certainly not the strength of the lens. MAF is quite fast, but often subject to focus hunting. I have an EOS R and the situation does not improve by changing the type of focus point. A few too many indecisions, especially when lowering the contrast or lighting starts to run low. Far from the behavior of my 28 mm Canon with USM motor... Furthermore, the fact that it does not have the internal MAF is another negative point, but we must consider that at this price there is some compromise. Now let's talk about nice things: the automatic correction of distortion in the room on JPG files is really prodigious. It works perfectly! A little less perfect the correction of the vignetting, but nothing to worry about. The minimum focusing distance is incredibly small. No centering problem, and I think no one has it with such a simple optical scheme and such small lenses. The optical yield of the lens is high and constant in the center of the frame. The lens is very sharp already at TA, shows a very slight improvement at f / 4 and remains nice sharp even at f / 11, with differences between the various imperceptible apertures. Situation a bit different at the edge. At f/2.8 the extreme angles are a bit soft, but which ultra-wide angle of this focal length (and this price range) does not suffer from such a problem? Closing the situation improves in a rather visible way passing to f / 4 and to a lesser extent closing f / 5.6, aperture at which the optical yield of the lens is higher. Beautiful colors. The incisiveness is very good, even excellent I would say, but not record-breaking: the aforementioned Canon 28 mm f / 2.8 IS USM is a span above, even if the comparison is not really correct as it should be compared to a similar focal length lens. Speaking instead of chromatic aberration, the software corrects it perfectly and by eye I have not noticed any color fringe at the end of the frame so far. The overall judgment on this perspective is still very good, I am satisfied with the purchase. I reserve the right to do further tests to evaluate for example the resistance to flare, bokeh and more ... sent on November 10, 2022 |
 | Canon RF 85mm f/2 Macro IS STM Pros: Excellent sharpness, optical performance in general, low weight, reasonable price. Cons: Autofocus, it does not have internal focus, it lacks the hood and is not tropicalized, but everything you can not have for this price! Opinion: Arrived just today, here are my first impressions. I will use it on a Canon EOS R, without a stabilizer in the car. And starting from the stabilization, I must say that this 85 mm almost completely keeps what it promises. Up to 1/8 of a second you can shoot (if you have a fairly firm hand) without incurring the move, this means that the effectiveness of the stabilizer exceeds 4 f / stop. Sharpness: exceptional! The thing that surprises me is the uniformity center / edges, just as befits a macro lens. Moving from T.A. to f/4 I almost do not see the variation in sharpness at the edges, which is already excellent at full aperture. From an optical point of view nothing to complain, indeed a round of applause to Canon that has managed to create a lens with a relatively low price with this performance. Other advantages are certainly the low weight, obtained thanks to the fact of having used many plastic elements. Let us now turn to the slightly less positive things. The most serious one is the autofocus: despite having read all the reviews and knowing that it is the Achilles' heel of this lens, I expected much more. In photographic use (and not to shoot videos, in this mode I have yet to try it), it is not particularly fast, it is noisy and sometimes even the lens is missing. It seems that the STM engine struggles to move the lens assembly, as I had read in an authoritative review. As for the reliability of the MAF, I almost have the feeling that it is a firmware problem... Another thing I don't like is the fact that I don't have internal focus, so the barrel extends. In short, if you are looking for maximum optical performance like myself, you will be very happy with this RF 85 mm, but if you look at the focus you will turn up your nose a little. sent on March 16, 2022 |
 | Kenko Teleplus HD pro 2X DGX Pros: Sharpness in the center, reads the diaphragm correctly Cons: Af does not work with the Tamorn 70-200 g2, high vignetting at TA, non-negligible chromatic aberration. Opinion: Recently purchased to double the Tamron 70-200 f/2.8 g2 with Canon EOS R and its adapter. I confirm what Mrsbpier wrote, the AF does not go, but fortunately with mirrorless you can use the manual MAF with 10 x magnification on the electronic viewfinder and you're done (better than with focus peaking, which is sometimes not as accurate). The stabilizer works, instead. The image quality surprised me positively, even at f/5.6 it is better than at f/8! Excellent central sharpness. Visible vignetting at TA and chromatic aberration, both correctable in post. With the Sigma Art 50 mm f/1.4 the MAF works, but it is not precise, better also in this case to use the manual one. However with this lens the surrender did not drive me crazy ... Unfortunately, my first specimen was decentralized. I had a second sent to me and this is better, even if it's still not perfect... sent on January 16, 2022 |
 | Tamron SP 70-200mm f/2.8 Di VC USD G2 Pros: Excellent sharpness, beautiful colors, bokeh, fast and reliable autofocus, very effective stabilizer, pro level construction Cons: Weight, dimensions (on the EOS R it is really large, also taking into account the adapter ring), a bit of TA vignetting Opinion: I bought the Tamron SP 70-200mm f/2.8 Di VC USD G2, used, to replace two lenses in my possession: the Canon EF 70-300mm f/4-5.6 IS USM II and the Sigma 105mm 2.8 EX DG Macro OS HSM. I use the Tamron on Canon EOS R, obviously with adapter ring. Due to the price out of my reach for the original Canon 70-200 RF, both the f/2.8 and the f/4, I opted for this lens of which I read great reviews. In the past I had tried the previous version that had pleasantly impressed me for the optical quality, a little less for the focus, not as fast and reliable as that of the Canon. Returning to the G2, The first impressions coincide with those of the reviews I have read here. First of all, the optical quality is really excellent, even at full aperture, certainly comparable to that of my (former) Sigma 105 macro at the same focal length. The autofocus is also OK, so far I have not encountered any uncertainties with the EOS R, even in low light conditions. It will be slightly less fast than the corresponding Canon but for the use that I make of it (portraits, landscapes, not sports photography) enough and advances ... The stabilizer is very effective, let's say that up to 1/30 - 1/40 s I had no problems with moving, surely the 4 f / stop declared are all there. So, let's talk about the slightly less positive things. The biggest problem is weight. 1 kg and a half plus a hectogram of adapter make 1.6 kg: you can certainly not think of wearing it hanging around your neck, if not for a short time. After a few freehand shots, although you can keep it firm thanks to the excellent stabilization, the left arm begins to sore and you have to let it rest. I recommend, when possible, to use a monopod, not so much to stabilize the lens (by the way, in what position should you hold the VC in this case?), but not to burden the arms. Let's move on: the EOS R, while recognizing the lens when mounted, has no data to be able to activate the corrections of chromatic aberration, distortion, vignetting etc. Fortunately for chromatic aberration this Tamron has none, the distortion is present but not a problem, while the vignetting is visible at the widest openings. The only way to correct it is to act via software. I use PT Lens that also corrects the distortion automatically but through the profile of the previous Tamron 70-200, with slight discrepancies. Overall I am extremely satisfied with this Tamron lens purchase, which I preferred to the rival Sigma Sport because of the 3 hectograms less weight and the lower cost. I highly recommend it, but don't use it for casual trips: too heavy and cumbersome! sent on November 30, 2021 |
 | Canon EOS R Pros: Robust and well-made body, with optimal dimensions (neither too small, nor too large), firm grip, great versatility but only for pro use (in fact the scenes, the panorama function etc. are missing), instant autofocus (not a shot is missed), well-made touch interface, Dual Pixel Autofocus, excellent image quality Cons: Ergonomics of some very questionable controls (moreover, from the customizable keys you can not manage all the functions), unconvincing video performance with showy 4K crop, absence of the stabilizer in the room, limited battery life if you do not use some precautions on energy saving, processing processes a bit slow in certain circumstances, evaluation measurement too variable depending on the frame Opinion: I have owned this camera for a few months, having purchased it in July 2021, but I think I can already give an accurate evaluation. I state that I also own an EOS 6D purchased in 2014, which continues to do its duty. The aspect that most impressed me is the quality of the images and that confirms what all the reviews say. Being a journalist / reviewer of cameras and lenses, over the years I have had the opportunity to try almost all the SLR / mirrorless of various brands and price ranges and I must say that a quality like that EOS R in terms of fineness of detail, micro-contrast, color rendering, I have never found, even with machines of the same House (apart from the 5D mark IV) or others with a denser sensor, which goes as we know at the expense of noise. If we exclude the unattainable Fujifilm GFX 100, which however is large format, I therefore put the EOS R at the top of the full frame cameras, even if - I admit - I have not yet had the opportunity to try the R5. I mentioned the noise, content, but the EOS 6D is better: after all, it also has 10 Mpixel less. The video quality is not up to that of the photo sector: although using it very little in this mode, I found that the recorded is lower than that of cameras such as the Sony Alpha 7/9 or even the Fujifilm from the X-T3 upwards. But, you know, an EOS R you don't buy for video... This machine suffers from some flaws that we would not have expected from a manufacturer like Canon and that concern ergonomics, where generally the manufacturer had never failed. Is it possible that every time you take your hand your thumb ends up on keys that should not be pressed? Never happened on SLRs, at least in full frame that have a better studied body shape. The touch controller might have been a nice idea, but it's poorly implemented in my opinion. In conclusion: excellent autofocus, totally adjustable touch monitor, well-made menu structure, very nice EVF (but the optical part of the same could be slightly better), great versatility. However, the stabilizer in the car is missing... And the battery, if you use the high frame rate of the electronic viewfinder, lasts very little... sent on October 06, 2021 |
 | Canon EF 24-105mm f/3.5-5.6 IS STM Pros: Extreme sharpness, low weight, very good construction level Cons: Coma, not really small size, only f/5.6 to 105 mm Opinion: Taken very recently (May 2021) after reading all the possible reviews, I needed an all-in-one lens to alternate with my fixed optics to avoid carrying a 6/8 kg ballast each time, as well as having to change the lenses themselves too frequently, perhaps losing "the fleeting moment" for not having mounted the right optics at that time. I would like to point out that I use a Canon EOS 6D and am a reviewer of cameras and lenses, having worked for several years for industry magazines; this work gave me the chance to really try many optics, both original and third-party Canons. The EF24-105 impressed me with the optical yield, which even exceeded my expectations. In the center it is indistinguishable (with my reflex) from sacred monsters such as the Canon EF 24-70 f/2.8 L USM, the Sigma 50 mm Art f/1.4 and the excellent Canon 28 mm f/2.8 IS USM, at their respective focal points. Only at the extreme edge you can see a small difference from those listed, especially at 24/28 mm, but just close a diaphragm or two to recover and have from f5.6 to f/8 an excellent sharpness to all focal points. Perfectly correct chromatic aberration in the room by shooting in JPEG, the same for vignetting. Only a slight cushion distortion of pins is visible at the longer focals, but with a program like PTlens you can automatically correct it as the profile is present. And of course also at the wide-angle focal points... I didn't find that described phenomenon of the barrel game, maybe over time Canon corrected the flaw. The only note is the very evident coma, especially on the shorter focal points and a brightness at 105 mm of only f/5.6. However, given the price, you couldn't honestly ask for more. I highly recommend it! sent on May 23, 2021 |
