جناب قدیری به نظر من اصلی ترین مشکلی که عکس شما دارد عدم کنترل درست نور بوده.
قطعا" اگر جایی در محیط باز و نور بهتری بودید نتایج از این بهتر می شدند.

آقای خلیلی اگر برایتان امکان دارد، عکسهایی را که در پستهای اول گذاشته بود و ظاهرا" دیگر روی سرورشان نیست، دوباره آپلود کنید، ممنون میشوم.

رویوی فتو زون برای 200-70 نسخه قدیمی (1) :

Verdict
There have been horror stories floating around the web suggesting the amount of vignetting and lack of sharpness of this lens at its long end is so terrible that it is barely usable on FX.
Well, to put things into perspective, there is some vignetting of course and it's a little higher than it should be, in addition the extreme corners show visibly less resolution at 200 mm. However apart from these two issues the lens performs on a very high level and produces very sharp images with very smooth bokeh.
The build quality is excellent, AF is very fast and silent, VR works as promised, allowing for 2 to 3 stops longer shutter times (with a suitable, i.e. non-moving subject). Obviously some thought and user feedback has been put into the design of the lens leading to useful features like the AF stop buttons, the removable tripod food or the lock on the hood.
The performance with tele converters is not too impressive, though. The TC14 is certainly an option to extend reach and still get excellent sharpness, at least in the center when stopped down. The TC17 might be suitable for some needs, however combined with the TC20 the results no longer convince and it's questionable if a simple photoshop crop and resize would lead to worse results.
However, in summary the Nikkor 70-200 VR still is an impressive lens, which for many becomes even more attractive now that the prices for used lenses come down after the introduction of the version II model. Given the amount of sample variation we saw, though, it might be a good idea to carefully check for softness wide open if you plan to purchase used.
و این جمله در ابتدای رویو در مورد دلیل فراگیر نشدن رنگ سفید این لنز:
پ.ن: واقعا ً جای تعجبه که برای این لنز یک تاپیک مستقل درست نشده بود!!The close similarity to Canon's long L lenses might be the reason why the grey lens was not very popular among the Nikon community and is a rather rare sight.
درود
جنای قدیری ! خیال دارید این لنز رو از چشم ما بندازید :confused: :biggrin:
مدتهاست میخواستم سر فرصت از شما بپرسم لنز 80-200 شما امکان نصب تله کانورتر را دارد. آیا تا حالا با تله کانورتر فرصتی برای تست دست داده؟ که آیا دست یابی به فاصله کانونی بیشتر بر افت کیفتی میچربد یا خیر؟
با سپاس
انوش
کدوم یکی از این دو لنز تو ایران پیدا میشه ؟ قیمتشون حدودا چقدر درمیاد ؟

بررسی200-70 روی بدنه فول فریم در SLR Gear :
کد:http://www.slrgear.com/reviews/showproduct.php/product/134/cat/13Alternatives
Nikon 70-200mm ƒ/2.8G AF-S ED VR II ~$2,300
Sharper - especially at 200mm - is the bottom line on the new lens, although there are also improvements in CA resistance and corner shading. The new lens is also slightly shorter, the focus stop buttons are gone, the distance scale is relocated to a more convenient place. If you're not bothered by the ''close-focusing'' controversy, then there isn't much of a reason to buy the old version of the lens.
Nikon 80-200mm ƒ/2.8D ED AF ~$1,100
If you don't need vibration reduction, the older 80-200mm Nikkor is an excellent alternative. For sharpness, the 80-200mm is quite similar to the 70-200mm, perhaps not as sharp at 80mm, but CA performance is slightly better and distortion isn't as prominent.
Sigma 70-200mm ƒ/2.8 EX DG OS HSM APO ~$?
Sigma's options in the 70-200mm categories are extremely competitive: Sigma has released three versions of its 70-200mm lens over the past years, each with significant improvements over the previous model. The latest iteration includes Sigma's stabilization technology (''OS''). We haven't yet tested this version of the lens, but the original HSM version was extremely competitive to the Nikon, not quite as sharp wide open at ƒ/2.8, but much sharper at 200mm. Other characteristics - chromatic aberration, light falloff, and distortion - are comparable.
Tamron 70-200mm ƒ/2.8 Di LD IF Macro SP AF ~$750
Tamron's 70-200mm ƒ/2.8 isn't optically stabilized, but provides comparable, and in some cases better, performance for sharpness than the Nikon 70-200mm. At ƒ/4, it's tack-sharp across the frame between 70-100mm, and is generally much better at 200mm than the Nikon (though by ƒ/8, they become quite similar).
Conclusion
For Nikon shooters, the 70-200mm lens has been the de facto pro lens, and until the version 2 of the lens came along, it was the optical king of the hill. There was always the lingering question of corner performance, and while in our review lens there are some soft corners, it's not the worst we've seen. What's worth noting is the number of lenses we had to test before we found a good copy - three - meaning that if you find a good copy of this lens, treasure it and don't let go. Otherwise, if sharp corners are important to you, look no further than the updated version of this lens.
