E system 43 focus speed on OMD em1

<p>Hi,<br>

I'm currently shooting with an em5 and a Pen epl5. I recently picked up a 43 system 14-54mm 2.8-3.5 lens which I love. Built like a tank and superb optical quality. <br>

However, as I'm sure you folks know -- there's an aggravating delay in auto focus. I know that the em1 will focus "up to speed" with the E system lenses. -- I'd like to know though just how fast this focus speed actually is. Does the em1 focus with 43 lenses as fast as with micro 43 lenses.<br>

I'm going to keep the 14-54mm lens but I'm thinking about getting a used em1 body for the enhanced autofocus performance.<br>

Would this be worth the expenditure???<br>

Thanks<br>

<p>Hi Peter,<br>

I have the M1, M5 and E3 including the 14-54 Mk1. I can confirm that the lens will focus much faster with the M1, basically acceptable, but not as fast as the 12-40 PRO which i just recently acquired. My main problem or dislike with the 14-54 is the size and weight compared to the 12-40. Sharpness and contrast are very similar between the two lenses. I hesitated a long time before buying the 12-40 because of the weight and size, but when traveling the zoom is very convenient.</p>

Fast is relative to each individual I guess. I used the lens you speak of with the E-3 and I know have tried it with the E M1. Just fine. And you may want to be on the watch for the 50mm macro which is also robust and not all that large in size. The 50-200 mm is a bulky addition to the E M1 but it also works well even at tele length. So my feeling is that Olympus did a good job in getting its old lenses to do their thing with the E M1 sensor. I expect that the older lenses will continue to have a lifespan. Why not take them if a bargain presents..

The Em-1s (Mark l and ll) are, in

fact, the only micro43 that have

phase-detection autofocus, the

only way to get quick and precise

af. "Old" 4/3 lenses are about

useless with other m43 bodies,

unless you have the time to

magnify the image in the

viewfinder. I used a EP2 with VF4

finder with medíocre af results.

My new Lumix GX8 is a bit better, but

still very slow. You can still

get a new EM-1 for less than 700

euros in several sites, such as

purnima-digital, where I got mine

for 530 € 18 months ago.
