look out 200 f2!
now, 200 f2 vs 105 f1.4
they are completely different tools
similar to RPG vs M16.
one can do a little more damage than the other, but both are dangerous.
one is a little easier to manage on a daily basis.
therefore, the 105e may become the new "go-to" special weapon for the mobile guys. guys who shoot weddings and engagement sessions, people who shoot their families, or do portrait sessions with kids (who don't want to be so far away).
I think of it as the 85L
while the 85 1.4g is amazing, it doesn't have that "it" factor.
the 105e does, it's just special.
main take away regarding the 105e is that it has the swirl and bokeh of the 58mm 1.4g, but the 105e is sharper wide open.
I don't deny that the 105 f1.4 is a better choice for day to day shooting vs the 200 f2 but to compare it to the 200 f2 by saying the 200 does "a little more damage" is a bit of a stretch. The comparison between these two lens has been made on several other sites with what I believe to be the best one over on the FredMiranda forums. The individual who has a 105 f1.4 actually likens it more to the 85 f1.8G rather than the 200 f2. They posted photos taken between the 105 and 85 wide open and while there is a slight difference of course in bokeh and compression the sharpness of the 85 f1.8 even at f1.8 definitely held up quite well when comparing the like images making it a negligible factor when considering either lens. The contrast of the 105, especially at f1.4 was more noticeable so that was a plus factor for anyone considering a 105 f1.4.
However, the 200 f2 is better than either of those lens when you consider the overall quality of the bokeh, contrast and sharpness of the lens. A huge weakness of the 200 f2 if one was shooting handheld all day would be the weight, I've done so and it is telling on the arms/neck/shoulders. Of course if you own a 200 f2 then you know this before making the decision to own one.
Please don't take what I've said the wrong way, I would love to own the 105 f1.4 and do plan on purchasing one when I can find one for around $1500. It may be a few years from now after the lens has been out for awhile and either a used or refurbished copy but I do plan on owning one at some point. I love primes and the 105 f1.4 has changed my plans for my next high dollar lens purchase.
