The following opinions have been automatically translated with Microsoft Translator. | Sony FE 1.4x Pros: All Cons: nobody Opinion: I have had several duplicators of various brands, mostly Nikon and I must say that all of them did their duty but with a slight loss of values such as sharpness and color rendering. This Sony one, very compact, has a stratospheric performance so much so that, since I bought it used four months ago, I have not removed it from the 200-600 and now I consider that I have an 840 mm at full power. I don't care about the loss of brightness because I usually only hunt for photos when the light is good and then I love to shoot at relatively close distances. Therefore, to have a decent PDC, which at short distances from the subject is almost always insufficient to cover it all, closed apertures are welcome. sent on November 17, 2024 |
 | Tamron SP 150-600mm f/5-6.3 Di VC USD G2 Pros: Given the price: pro in everything especially in tropicalization and the minimum distance of the MAF (2.2 Mt. is a lot of stuff) then the weight of course Cons: Compared to the brighter optics on certain sensors it loses speed on the MAF especially in low contrast and light scenes, Chromatic aberrations are lurking but in pp they can be corrected Opinion: I don't want to go into so much detail because it suffices to say that I sold the 300 2.8 because it was too short for bird life with the intention of finding one used with a longer focal, when in the meantime I purchased this zoom while remaining appalled by the results especially on sharpness. I read that many find it blurry at the longest focal points but I honestly find it very clear even at 600 mm. Certainly the longer the focal point, the more you have to be careful about vibrations and imbalance, precisely of that physical elongation that it has, criminalizes it very much, especially by hand. I have three cameras: as far as calibration is concerned, I will say that on the D7200 it goes perfectly and even on the Z6 that has no levers and various mirrors there was no need for calibrations. On the D850 calibrated on the eyes of the birds at the zero km hut there was a need for a +7 on the fine adjustment of the menu. Of course he can't stand the comparison of fixed optics like the 600 F4 but if you are professional and turn the world so much by smearing the equipment between deserts and rocky mountains he is not suitable because its structure is delicate. For my use that I pass from one zero km shed to another on the river or the nearby forest enough and advances with the advantage of having a handful of focal points in a single lens and the advantage of focusing already at 2.2 meters (the 600 F4 A 6 Mt). In conclusion, after a year of use I am very satisfied with it and I do not know if I will buy the longer fixed focal point. I still lack freehand testing to test the speed of the AF, so I promise to add the results. sent on June 17, 2021 |
 | Nikon AF-S 300mm f/4 D ED Pros: Minimum distance of MAF, quality/price ratio, sharpness and much more Cons: Nothing, or necessary change the attachment ring to the tripod to avoid any vibration that the one supplied unfortunately creates Opinion: I have been over half a century in the midst of the use of goals and I swear that ever I found a lens so perfect in everything.. The list of qualities of this lens sends those who try it: in short, try to believe. In sharpness beats even the Big Brother 2.8. Say mind-blowing is little and this confirms the lungotempo now that is on the Nikon catalog. sent on November 05, 2018 |
 | Sigma 180mm Macro f/2.8 EX DG OS HSM Pros: Perfection in fire, unparalleled sharpness Cons: Weight, size, price Opinion: To define with one word "FAVOLOSO". I came to mind to raise my mind by replacing the already good model 3,4 with this but I did not regret it. The old man went fine with the reflexes of the era like the D300 with regards to the MAFe AF, for the sharpness we are instead. I use it with its duplicate 1.4 Sigma even for avifauna when I can get close enough to the subject and considering that I use a 7200 in the end I'm in my hand, croaking on the room, almost a 500 mm with minimal focus. Stunning in all with unparalleled clarity (just see the MTF charts). Color rendering is great. With the fact that 1: 1 focuses on infinity, many fashion photographers are using it to open up close-ups of faces with excellent results. sent on September 08, 2017 |
 | Nikon AF-S 300mm f/2.8 G ED VR Pros: Quality and sharpness by fear. Exploits its multipliers returning perfect images that do not show any loss (makes it a little less at medium distances and infinite with respect to the fixed 400 -500-600) Cons: cost, size, weight Opinion: I tried them all his predecessors from the old Nikon 300 2.8 AF than twenty years ago that had the mechanical transmission dellAF and drove me crazy because at low temperatures did not want to focus on. But I would say that Nikon has remedied the great building future models and this with great strength and reliability. The speed is amazing MAF using it smooth. With the TC gradually loses more you get closer to 2X but it's still more than enough. The VR is very efficient even though I almost always keep it off because I do not like freehand. The weight is felt and it is easy to miss shots just for the burden on the forearms. Council to always use a tripod for photos in flight. A tool for professionals who really with her three TC replaces egragiamente other optical long, heavy, and expensive especially. sent on July 28, 2014 |
 | Nikon D7100 Pros: not considered to be an SLR professional beats all records for the achievement of maximum sharpness so far achieved only by FF D800E Cons: Buffer slow. ineffective wiper sensor on Nikon AF lenses and dated I noticed inaccuracies AF and hesitations, sound pretty obvious after 800 iso, but you know that those sensors without filter highlighting well as the sharpness even the graininess. The crop factor is great in quality but I preferred that the cut side is obscured when you use it now as you tend to make mistakes easily by cutting the soggettorn Opinion: I do not understand those who try such a machine in just a few days .... I was one year that I own and I still can not say I know all too well if the use of hours almost every day. From gape from the results in sharpness that you can pull out. I think it is useless to spend twice as much for a FF such as the D610 while excellent, too. Contrary to what some say this camera is capable of bringing out the best optics also not expensive. Problems with moire ever seen in twenty shots. As for the 'AF is very fast and accurate with the optics of the Nikon with the universal .. I had some problems but I think it's the fault of the internal form of these very dated compared to the processor 7100. The burst speed is slow but with SD something you can do .... still good enough for the photo hunt. I also disagree with those who claim that the shake-sensitive: in my opinion is as sensitive as any other except that here it demands the ultimate in sharpness and certainly a minimum of vibration you feelking. For the noise I've already said above defects but is easily manageable with programs like Neat and Topas. In short, a reflex amazing considering the quality / price ratio. Its 24 million pixels are so dense in ODA as a proportion that exceeds the D800E. The battery shots only if you forget it ..... only if you turn on the monitor for a long time as I do with every shot in the shed and to monitor the success of the shots may be that at the end of the day you should start charging the battery or you will be impression of never ending. The power of the machine has to crop in amazing! practically stretch the optics of 1.3 X and you're holding a sensor that is equal to the density as D7000 sister. Impressive results! Not to mention the particular fondness for shooting macro and micro that make you touch the ultimate in detail with this camera. Jpeg files are great and can be used immediately and surprise I noticed that even if you expose raw right are pretty much ready with very little PP. I have not tried many SLR for now and I do not know canon but between d300 - d700 - d7000 - ranking D800E D800E in my opinion this is the palm of victory .. and immediately turn the D7100. sent on June 19, 2014 |
 | Nikon AF-S 70-200mm f/2.8 G ED VR Pros: Lightweight, very handy, excellent optical quality. Fast and secure AF. VR effective Cons: The only defect (this is why version II was made) on the FX are practically unavailable 2.8 and 4 diaphragms for strong vignetting (remodable though in PP) Opinion: In my opinion, I have tried hundreds of goals this is the absolute best in terms of sharpness and blur and all focuses. I believe that it practically bats many fixed focal points. In combination with CTs is fine but the optical yield drops. The AF is a splinter, and especially its extreme lightness makes it very manageable even with manolibera with a really perfect VR. sent on December 27, 2012 |
