The following opinions have been automatically translated with Microsoft Translator. | Nikon AF-S 300mm f/4 D ED Pros: Robust. Handy. Diatanza minimum focus. Quality / price ratio Cons: Tripod insane. Without VR Opinion: Very sturdy, virtually all metal, which is very useful since it is a lens that is on the "field". It is appreciated the minimum distance of focus. I abbinavo converter 1.7 and did a "macro" of insects that can not be easily approach. 's AF is not lightning, it gains in speed using the limiter. With 1.7x the quality is reduced compared optics smooth (but still good) AF continues to operate even if it becomes much slower. I consider it very good perspective that is worth all the money spent on the acqusto, able to give great satisfaction. It is a lens that I do not, I sold it (bad!) to finance the purchase of the 300 f/2.8, and for close-ups to tell the truth I feel sorely missed. sent on October 30, 2011 |
 | Nikon AF-S 70-300mm f/4.5-5.6 G ED VR Pros: Excellent quality / price ratio. Excellent performance from 70 to 105. Compact. Cons: The front part, which extends by increasing the focal length, perplexing on the mechanical strength. The optical performance decay after 200 Opinion: The angle of the field covered by this lens on DX digital sensor is equivalent to that of a 105-450mm, and a range that covers all the focal telephoto used, those from portrait to super-telephoto camera for hunting and sport . The objective is well balanced if used with a body DSLR class of D300, which has roughly the same weight of the lens. The motor Silent-wave allows a rapid focus, although not equivalent to that of the optics of the upper class (70-200 f/2.8 VR for example). Coupled with the 18-70 I used it on many trips and excursions where I wanted to be "light" with full soddisfazine. sent on October 29, 2011 |
 | Sigma 10-20mm f/4-5.6 EX DC HSM Pros: Good sharpness, robust mechanics Cons: Problems with AF. Opinion: With my copy, I have the autofocus that locks up occasionally and for no apparent reason. It happens in the most varied conditions of focus. Moving the ring for manual focus, everything continues. This happens on both the Nikon D100 than on the D300. (Although I doubt the validity of the quality control of Sigma) I bought this light (new) in 2007. Using it for photos of paesaggo this problem is more of a "nuisance" so much is that they are holding me so. For all the rest are happy with this lens. I just wanted to report this problem to warn that he was going to buy optics used preriodo of that and put it on D300. (There will be only my fault with this?? Ho I am the loser!). sent on October 21, 2011 |
 | Nikon AF-S DX 18-200mm f/3.5-5.6 G ED VR Pros: Flexibility of use Cons: Rather delicate built = bad Opinion: I find it a 'optic im very comfortable journey, in those moments that you do not know or can not predict that focus may be helpful to take a moment after something that we can no longer, or not worth the trouble shooting. Is very useful to vary widely, the focal length without changing the optics in very dusty-sand (Deserts, African tracks etc..). You can not say that it is an objective robust! I got out of hand as he slipped and fell on the damp ground and making a flight of no more than 60 cm. I found the lens open in TWO parts! The repair was going to cost me 50 euro in less than a new objective. Since I consider it very useful for the type of trip that I usually do, I bought another one. After about 2000 shots of the second objective autofocus stopped working. This time it occurred the warranty. To date, this copy I made a little less than 14,000 shots and sides of rubber rings which are the zoom and focus are loose (a bit like the rubber bands that eventually lose their elasticity). Perhaps this last is not a defect but is due intensive use. sent on October 10, 2011 |
 | Nikon AF-S 105mm f/2.8 G ED VR Micro Pros: Contains virtually all the advanced technologies from Nikon: Nikon anti-reflective coating N (nanocoated lens), ultrasonic motor (AFS), a very effective system of vibration reduction (VR) Cons: Maybe a little? big Opinion: In hand conveys a feeling of strength and solidity and mechanically seems well built. This is not to say that vuolo can not break. Focusing the lens vertically downwards in autofocus and I had a break of the same. Now vertically, as a precaution, I always focus manually! Very clear right from the maximum aperture to f / 8. From f / 8 onwards close the diaphragm does not lead to an increase of sharpness (that is reduced), but only of depth of field. I tried to use it with the TC 20E III and the results were very positive, even if the combination is to be considered for casual use. But I can say that although the lens is versatile and can be used for landscapes, portraits, etc.., Is a lens that results from high level when shooting at close range and macro. sent on October 08, 2011 |
 | Nikon AF-S 300mm f/2.8 G ED VR II Pros: Extremely sharp from f/2.8 to f/11. The build quality superb. The blur is great. A lightning autofocus. Cons: The money that you have to pay for it. Opinion: The lens is very well balanced. I use it with the D300 + battery pack (all greater than 4 kg) and you can pretty much work by hand for quite some time. The next day, however, the arm enlists the help of a support. The autofocus is very fast, with the limiter is stunning. With the 2x TC you get a 600mm f/5.6 Compact and handy that does not require major logistical problems, especially in air travel. Obviously becomes softer, the focus speed is reduced but it is still high. To take a good support is essential to 600mm worth meet in the shots of the shake at best. sent on September 28, 2011 |
