Pros:optical performance, af speed, lofty building, manageability
Cons:but the price you pay
Opinion:I had the first ef 300 f2.8 the fantastic goal, but the transition to this 300 and 'difficult to match to a rise I particularly appreciated the handling and the ability to use it freehand about even the stabilizer 4-stop, rapid in focus an exceptional combination with the eOS 5 mark iv, only flaw the price
Opinion:I own a few days, but I was really impressed by the quality of this lens. No multipliers of course its best but I must grant him an exalted sharpness also multiplied (iii series with extender). With 2x autofocus loses accuracy resulting difficult to use for fast-moving subjects. I use it both with 5d mark iii that with 7d mark ii. The stabilizer is definitely one of the best I have ever had the pleasure of using. All with a very low weight.
Pros:crystal clear, optimum efficiency even with multipliers, compact and lightweight to be a big lens, AF and stabilization to the top
Cons:high price, but justified by the quality of optics
Opinion:In my opinion it is the best super telephoto for travelers: it is much easier to carry around than the 500 and 600mm (weighs 2.4kg and is 24cm long, compared with 40-45 cm of the canvases more) and has a truly extraordinary performance . The image quality is really perfect from corner to corner even on the most demanding sensors, such as the 50 megapixel Canon 5Ds, and you can take advantage of the f / 2.8 when taking pictures in low light and have a great separation from the background. Mentra the previous version leaked a bit of quality with multipliers, the Canon EF 300mm f / 2.8 L IS II USM also remains incredibly crisp with 1.4x and 2x TC, to the point of being fully usable on any sensor also multiplied to 2x and shooting at full aperture. The excellent performance with multipliers makes it very versatile: with one lens you can have 300 f / 2.8, 420 f / 4 and 600 f / 5.6, covering most focal lengths that can be used in nature photography. The build quality is to massimlevels, solid as a rock and tropical conditions; the autofocus is the fastest you can get, and the excellent image stabilization makes it easily usable without a tripod. The only "flaw" that you can find is the very high price, almost double compared to the previous version, but justified by the performance of the highest level.
Opinion:I purchased the lens about a year ago and it is the lens that more use, even if I have the 500, always ii series. And 'light, versatile and high performance with the 1.4 extender. Personally, I think the 2x should be used only in an emergency and not for the photographic hunting of the airborne side. The sharpness remains high, but the speed is reduced, in my opinion, greatly. The sharpness reaches such high levels by having to limit the detail in post production. I projected some images, using a 55-inch OLED TV and the definition remains awkward. No loss. Council to make the optics microtaratura to take advantage of all the features it has. The autofocus is very fast and very quiet, which is crucial for you then very close subjects, from the shed. I owned the previous version, and I sold it because the yield, especially with the extender, was not excellent. The weight and volume content, permettonor go around the world, with a baggage really "light" and versatile. Highly recommended.
Opinion:Lightweight, af fast, excellent image quality. I had the previous version and the difference in speed and sharpness is remarkable. Is quiet and effective, innovative position 3. With the yield extender is also unparalleled with 2x. With 1Dx SLR and former. series 3 reaches the maximum. The quality you pay for.
Opinion:I can not find flaws, rather just clicks you realize the image quality. l 'autofocus quick and quiet. I was impressed with the quality tc2x, I use it both on D1X 7DMark2 that on, you are from a 300mm to 960mm in a moment of pure quality. I recommend it with flying colors with honors, this time at home Canon outdone herself
Pros:Versatile and lightweight, excellent with multipliers.
Cons:Price
Opinion:After using it for several years, the 300 is F4 and for a year I bought 400 F 5.6 300 2.8. The excellent construction reveals immediately that you are in front in front of a perfect product from every point of view. I immediately appreciated the effectiveness of the stabilization and sharpness that leaves you speechless to 2.8 (where it reaches the highest levels) but is also great with the extender. Autofocus is fast even with the 1.4x slows down a bit 'with 2x without limiter distanza.rnUsato with APSC APSH or (as in my case) is very versatile and suitable for all types of photos naturalistic thanks to extender.rnIl Price is the only real limit. Recommended with extender series III. Rated 10 and praise.
Pros:Everything a photographer could ask for from a professional optical
Cons:But the price is a harrier
Opinion:What about quest'ottica.rnECCEZIONALE !! rnCon only 2.4kg is a great travel companion and putting in his pocket and the two multipliers 1,4xlll 2xlll have a park completo.La optical clarity is amazing personally one of the best ever tried and f2 / 8 breathtaking !! Why quit when you can have the most wide open?! ... Only for PDC! Af as the term, ultrasonic decreases slightly with the former but remains at very high levels, as construction you can not ask for more is sturdy and well Balanced perhaps the companion who will never betray you you orders him run! definitely capable of enhancing the megapixel of new canon.Il price!?! ... high but if you carry with you will make you forget everything!
Pros:Sharpness at maximum levels, weight, size, stability, and high quality construction with tc.
Cons:The prohibitive price
Opinion:Along with the 400 2.8 is ii, is the lens that offers all the quality you would expect from a Canon telephoto and a little more. In the test it I got confirmation of what they read on specialized sites: three paintings at a high level. With both multipliers has a fast autofocus and full-aperture image sharpness have to be sold, with the advantage over the canvas longer in size, weight, portability. Needless to say, as it offers without the tc, splits the pixels in the camera sensor. rnL'unica big downside is the high price.
Pros:Lightness, sharpness, micro-contrast and fast autofocus guaranteed even with both duplicators. MAF a minimum of 2 m. Optical equilibratissima that can be used easily by hand.
Cons:I found indecision in af camera with 2X III and 70d.
Opinion:Using this optical exclusively freehand and I find it light and fully usable with APSC with 2X III with subjects such as fast shorebirds in flight. The improvement over previous versions is the net especially with 2X III. He disappointed me a bit 'the speed of maf without extender, is slightly greater than that of the USM 25 years ago. But with the 2XIII the speed does not slow down at all, on condition of use cameras of the latest generation. In C aps sharpness it is unsurpassed even by the use of duplicating machines, right to the edges of the frame. Absolutely amazing 600 mm (960 with APS C) with the weight of just over 2.5 kg to which I add the 900 7dmk2. Great for shooting birds in flight, like swallows and bee-eaters.
Pros:quality, weight and minimum distance of focus
Cons:price ??? I do not think we can expect the moon ...
Opinion:phantasmagoric lens, I use it almost always with 2x III and loses nothing in it speeds it in quality. I was really impressed. have a 600 mm f5.6 in a backpack with a weight of 2.5 kg is priceless. chosen after long raggionamenti, you have three lenses in a 300 2.8, 420 4, 600 5.6, lightness and speed everything you need. For the series the mm are never enough ... if I had money to burn there affiancherei an old 600 f4 for use in the shed. Used until now with the 7D now you just have fun with it with the new 5D III.
Cons:You could still work on the minimum distance of focus; randomly quote the price ....
Opinion:Objective absolutely top livello.Velocità autofocus at the highest levels, already excellent resolution at full aperture. Significant improvement in the speed of focus with the two series tre.rnCon the Canon 1.4 extender ex III negligible loss of quality and minimum aperture accettabilissimo yet. With the 2.0 ex III good speed autofocus and medium-quality good and good already at full aperture diaphragm 8.rnIn conclusion a super-great lens to smooth trip, great 420mm and 600mm good as the need arises, with maximum lightness and portability.
