买吧，现在还扛得动想玩就玩，640TC最大的好处是内置TC，实在是方便。

安静漂亮！哥斯达黎加东岸度假屋门前看日落太阳下应该是亚洲了。

静兄长，苍鹭在西欧不算是候鸟，门口的小河常年可见，还有天鹅。G 600 F4 陪伴我差不多十年， 估计 600 TC 也是， 它没有想象中重，就手携带，而且靓仔。

这个是苍鹭吗？

以前从不拍街头的乞-丐， 但了解到这是一种来港旅游兼挣钱的职业，就没有了心理压力。

我兜了一圈， 最后还是想着640TC。 理由就是428玩过了，就剩640TC没玩了。

静资前贴提到428E，上老图 +1.4X

静、美

X2D 下一次更新固件能不能把焦点框改小了？ 现在对焦人头老是往背景跑，只能对焦脖子以下来保证合焦。

前几年流行养猫狗，碧街的水族店关闭了不少，有些店改做楼上铺，靠网络宣传来减轻成本。  现在好像宠物流行过去了， 不少宠物店都关门大吉了，水族店又慢慢多了起来。

个人觉得养热带淡水鱼和草比较容易打理 - 以前养了十几年热带鱼和水草，现在家里还有两套CO2气瓶和减压阀扔在柜子里。  当然海水鱼属于另外一个别轻易碰的专业。

这家店打我知道鱼街位置时就一直存在，卖鱼的方法也一直没变过。 当然我没帮衬过，因为热带鱼在这个小水袋里挂两小时，很大机会会感冒，买回家2-3天就挂。

看来赏花兄认真做过功课，Z 2.0 TC确实有点问题。   

送个大眼仔

关于Z428 TC外加1.4TC or 2TC, DP Review forum 找到的分享：

I own the 400mm TC and both Z TC’s. If you intend to use the 2.0TC for birding, then it will work well on the 400 to give you a 800mm f/5.6 that is every bit as sharp as the 800pf (for my uses). The 2.0TC plus the internal 1.4 gives you a 1,120mm f/8 which I have not yet found useful for any photographs I would submit to a gallery, etc.The 400mm plus an external 1.4TC gives you a 560mm f/4 and a 784mm f/5.6 with the ability to switch rapidly while shooting by using the internal TC lever. I do not print larger than 20 by 30 inches, and for my uses the 784mm is as sharp as the 400 plus a 2.0TC, or the 800mm PF. For me, I prefer to not change external TC’s in the field if I can avoid it. Thus, I prefer an external 1.4TC on the 400mm when I’m out birding with that lens to have the flexibility of effectively a 600/800 lens. The 400 plus a 1.4TC combination is also what I choose when out for large mammals like bears.If cost is not a major factor, both Z external TC’s work well on the 400mm f/2.8 TC…

I have the 400 and both tcs. From my experience, the 2x is a hair sharper than the stacked 1.4x. But I really have to compare at 100-200% to see the difference, so it's marginal as far as I can tell. I have no reservations about the image quality at 784mm or 800mm, they are both great to me.Image quality using the 2x at 1120mm for the most part is unacceptable to me. I think 1120mm works decently for animals at close distance. For medium to longer distances, I have a lot of difficulty getting a decent shot image quality wise and therefore am extremely hesitant to use 1120mm.I find I rarely use the 2x, but usually use the 1.4x as the marginal hit on IQ at 784mm compared to 800mm with 2x is trumped by the flexibility on focal length using the 1.4x. I only use the 2x only when I know I need max reach and don't need flexibility, and I pretty much only use it at 800mm.

Its convenient to keep the TC1.4X in my pocket (much smaller than the TC2X) and it works great. I also have the 800pf and use that when/if I know I need 800mm most of the time. If I think I may just need 800mm now and then I take the 400/2.8TC and a TC1.4X. Here is a few examples all shot with the 400/2.8TC with External and internal TC's, focal length for all these images is 784mm. I cant see a real difference using internal + TC1.4X vs just a TC2X. I never looked at 200% and why would I.
