This article was written last year. It was discovered before this year that it was not finished. Now that 12-35 has been left out, so there is only one set of comparative pictures.
Began to say that the next hand will have two coke-section cow heads. After using M43, there will be a lingering Ngau Tau dream, but the perseverance of 12-40 has been slightly higher, and then it will receive a 12 -35, drying sheet is below:

But my heart is not willing! The first two days saw a group of friends out of the 12-40, hood and lens cover slightly bumped, the price is OK, can not help but pick up, because it is second-hand, the box is miserable, it is not out of the box, put the play One evening, I said the feeling brought by these two lenses.
The first is the length, 12-40 is slightly longer than 12-35, where 12-35 is UV, and 12-40 is also placed on the 12 end rather than the shortest state, but still can see 12-40 is better than 12- 354 longer, the contrasting phone is NOTE5
Speaking of the shortest length of 12-40, it is about 16-17MM instead of 12MM, so when you screw to the far left, you will find that the lens is retracted and extended, and the shortest 12-35 is 12
12-40 is 62MM caliber, 12-35 is 58MM caliber, intuitively is 12-40 will be a big circle, plainly is the bigger eye
Ass is also 12-40 bigger
On the machine, and with the EP5, I personally feel that 12-35 is more coordinated
Side view, obviously 12-40 big circle, I feel a bit up. . .
Upper view, obviously larger 12-40 cross section
Picture comparisons are 12-35 left, 12-40 right, aperture 2.8, ISO200.
12MM. It can be clearly seen that the light source of 12-35 is smaller, but the glare at the bottom right is a bit obvious. In terms of picture quality, the center and corners are both 12-40, which is a bit better.
25MM, anyway, I feel it is half a catty, 12-35 is slightly better.
35MM still feels similar, but 12-35 is still a little bit better.
In general, the quality of these two pictures cannot be separated from each other.
to sum up:
To be small, anti-shake, buy 12-35.
To more 5MM, small macro, 12MM full open, buy 12-40.
PS: In fact, these two heads are good heads. At present, the second-hand price gap is about 300 yuan, Panasonic body buys 12-35, and OBA body buying 12-40 is quite reasonable in the past because Panasonic's body is not protected. Shake, and Obba has a powerful five-axis, but since the appearance of Panasonic GX85, Oboba out of 12-100, this truth is not so the past, now two advocates are body + lens image stabilization, so 12-40 is actually a bit behind the times. And why should I buy 12-40 for 12-35? Because I took the EP5 ah, do not support coordinated image stabilization, and there is the original feeling of Obama. But to tell the truth, if there is no small macro requirements, in fact, EP5 this body is more suitable for 12-35, from the appearance and weight are more coordinated. 12-40 this big block, or fit for EM1, even EM5 MARK2 point HOLD can not live this diameter lens.
