各位師兄前輩好!

我用緊Nikon D70s, 有kit lens, 又有Nikon 70-300(ED), 而家想買支Extender (2X)試下, 但記得以前呢度好似有師兄提過, 話原廠Nikon的Extender只支援AF-S鏡, 其他鏡唔得? 係咪呀? 可否請證實?

另外, 聽聞副廠反而重support埋其他鏡, 用落其他副廠鏡度亦沒問題? 那有那些牌子/Model好呀? (Kenko好唔好? 定Tamron?), 同埋佢地價錢同原廠係咪相差好遠呀?

若買2X的話, 質素係咪真係低好多呀?

謝謝!

Kenko最全面, 咩鏡都用得返aft咁滯, nikon就唔得好多鏡得, 不過2x就唔建議買, 成象麻麻, 我都放埋一邊唔用, 買過支長焦鏡好過

但買1.4X又好似冇咩分別咁....
其實都係好少影到咁長, 但貪佢方便同平, 有的話有時帶埋, 需要時可以影長d, 亦免得買一支長焦, 同埋成日帶住咁重 :)

副廠好似一千左右都有啦?

kenko 2x 賣8舊水, 你貪方便就唔好呀, 用左x2, 光圈細一半, 質素又低左, 紫邊又大條左, 對焦慢晒, 唔係想像中咁方便, 除非你用大光圈, afs, usm鏡. 不過咁, 幾舊水買來玩下都唔過份

Agree with kingkonghk, don't expect the picture quality will be very good as a long focal length len, but it's still worth for couple of hundred dollars.

I bough an used one at $350 only (Kenko 2x). Luckily I got this before I went to Johannesburg, my 300mm becomes 600mm allow me to take some good wild life animal pictures, which I didn't plan to. To bring a 600mm lens to travel? Forget it! (to me ^_^) Sometime I prefer "I can take that picture even though it's not so good in quality" rather than "Because want good quality I miss that picture at all". So, depends on what you need.

For your information, as for Kenko, the 1.4x is better than 2x in terms of picture quality when compare the two.

樓上的ｃ兄，請問你的300mm是否2.8光圈，加了Extender後，是否要手動對焦？
