AF speed: DA*300 vs DFA 150-450

Sorry if this has been addressed, but a quick search here and on google didn't bring anything up.

How does the AF speed (especially continuous AF speed and accuracy) compare between the two lenses in the title. I currently have the 300, which I love, but am pining for the 150-450 for the extra reach.

Thanks,

Jeff

Cheapest way for more reach would be the HD 1.4x tc. You'd have a 420mm f/5.6 lens. Although you've likely considered this already, but if you haven't...
The 150-450 is undoubtedly faster, I would think.

I already have a view...... will be interesting to see how Sandy feels.

Anyway, I'm mostly interested how the 1.4 goes autofocus wise on the 150-450...... especially so on the upcoming FF.

My view is simple...... both will give you great images, the 150-450 needs a bit more light. The 300 provides size and weight advantages, the 150-450 gives far more flexability. I exect the 150-450 is noticably quicker to focus (especially when selecting the long or short focus preset)

The 150-450 gives 50% more reach....given the 1.4 can be fitted to either.

The 300 is way easier to shoot with......

I have a F*300/4.5 ..... which is marvelous...... but I'd only take it with me these days when it's a smaller lens or nothing.

I live rural .... so wildlife'ish shots make up a reasonable ammount of what I enjoy doing..... so the extra hasle of a large lens is worth it for me.

The 150-450 is much faster focusing than the DA*300 f4. When using a TC on the 300, the best way to get focus is often to switch to manual and use catch-in-focus.

I have not got good results from the 150-450 with a TC - it works in a fashion but is too slow and better optically without the TC.

The DA 300 was over awed at the awesomeness and physical presence of the DFA 150-450 and subsequently cowed in the corner.

On a more serious note....... the weather was very wet so we didn't get to do much of a shooting comparison, however I do believe the view of the focusing speed is in line with Adrians observations....ie the 150-450 is noticably faster. Of course there is the obvious size difference one has to consider. In the end, Sandy was in love with my F*300/4.5!

I got to try the HD 1.4 tc on the 150-450...... which I thought was good..... so one of them for me at some stage.

She is indeed petite, and very beautiful, but I would say it was more of an aesthetic infatuation than love
I'm still committed to a long-term relationship with the DA*300 - AW and silent focus both matter for event work.

The DFA150-450's AF seemed to be just as fast with the HD1.4xTC as without it.
