Oh I'm sorry Steve, I was thinking you had one, and was wondering if you should get the 2x or not.


If you want the focal length, get the 100-400mm. If you want the sharpness and speed, get the 70-200mm. The extender just won't get you the same quality shots the stand alone lens will.


It all depends on what you are doing. I'll tell you this, the 200mm auto focuses LIGHTNING fast! It blew me away how fast and accurately the lens focused. The 400mm doesn't focus as quick, but it's still fast and accurate.


So, if you need the focal length, you should really get the 400mm. It has a nice clean, sharp picture and good IS. You'll be way happier. The IS works well. Granted it was a sunny day today, I hand held 400mm no problems at all. So, for what the lens is made for (brighter light) it works absolutely beautifully.


The 200mm, I took some indoor shots, and they came out beautifully. I should post some up here when I get a chance. Another great thing about the 200 is the bokeh. It's terrific! Absolutely gorgeous background blur. This would be a prime lens to do candids or portraits.


So, in the end, it all depends on what kind of photography you want to do. To get the best image quality you have to get one or the other without the extender. Like I've heard, when it comes to buying camera equipment you only want to cry once....and that's when you buy it, not over and over when you don't get the quality shots you're looking for.


Hope I helped. Post any more questions my friend!

PS: I will get an image from each lens put up by tomorrow on here for you, so you can see what I'm talking about.
