Hello Erik.

I recall that you have used both the TZ25 and the TZ60 (=ZS40) and below is Your comment about the ZS40 some 4 months ago. Now it seems that I'll POSSIBLY "have to" give the TZ 25 to my daughter, and I consider a TZ60 instead. Reading your comments about the iA of the TZ60, do you think that the iA of the TZ60 is worse than the iA of the TZ 25, with more "smearing" of details and/or much more noise?

This is a rather important point, because my wife would reasonably much use the new camera, and she wishes to use iA . The iA of the TZ25 has been good enough, so if TZ60 has a similar iA quality, then I think that TZ60 would be the right camera.

Best regards

Jahn - Det gör det samma.

I wouldn't worry about it.

If your wife likes iA on the ZS25, she will likely be OK with it on the ZS40. iA lets the camera choose EVERYTHING so the operator never needs to think about exposure, just "Point and Shoot".

But what I said, 4 months ago still holds: in atomatically doing everyhing, the camera will make choices that do not produce as good a picture as the camera is capable of.

Used the way I suggested, the camera takes the sharpest picture possible with that lens at that time. Since the aperture is wide open, the shutter is forced by the camera's metering system, to operate as fast as possible and - as I said - "fast is good in most cases", meaning that a fast shutter speed stops blur from subject motion, as well as helping the OIS to stop blur from camera motion.

In that way - and outdoors in daylight, shooting in "A" (aperture) mode is no different from shooting in iA mode: no choices need to be made.

My wife shoots in iA mode, does not wish to be bothered - why should your wife be different?

And, really, the average iA shooter won't notice the difference - this is for we "camera nuts" who will notice that at the smaller (higher number) openings, some leaves and grass will have a slight "smeared look", at least when "pixil peeping"

I basically give this advise when someone complains about "smearing": it's how i minimize smearing, although in most cases it's not really important that every blade of grass be perfect, I don't mean to confsue anyone, it's only for the "picky". (kräsen)

Ideally, your wife might be willing to use "A" mode ƒ/3.3 when spending the day in the park, and just switching to iA, but she will get acceptable pictures in iA because she's probably not as critical of the result as some are.

When you are operating the camera you can - of course - use any mode YOU wish to use if you want more critically sharp results. Or just relax and ise iA if you don't want to bother.

Det skall vara bra, i allafall.

Personally, I'd just get another ZS25 and a Clearviewer - even with postage from the US for the CV, the combination would be cheaper than the ZS40. I - personally - did not find the ZS40 to be any better for noemal photos and the EVF is so tiny.

Your mail some 4 months ago :

Emeybee, it's a crying shame you returned the ZS40 so soon. Your problem was not the camera - it was shooting it in "Auto" mode.

The camera can do MUCH better than you describe: "Auto" mode tries to satisfy everything by taking the "middle of the road" - and winds up unsatisfactory for most situations.

Whats happening, is this: The "Auto mode winds up "stopping down" the Aperture, and that degrades the image - particularly in random-detail areas, like grass. The cause is the phenomenon of Diffraction - the bending of light when passing an edge. It is inescapable, and due to the "wave Nature" of light.

Here's a lot more on the subject in case you are interested:

http://www.dpreview.com/forums/thread/3359835#forum-post-50571409

Long story short: if you always shoot in "A" mode, with the lens as WIDE as it can go: ƒ/3.3, you will minimize diffraction and get the sharpest pictures the lens is capable of. Period.

AND, as a bonus - since in "A" mode the camera selects the shutter speed, you will get the fastest shutter speed, automatically. Fast is good in most cases.

When shooting in "A" mode, the aperture and shutter speed are displayed at the bottom of the screen. In poor light, if the shutter speed gets too slow (say below 1/30th second) upping the ISO will give faster shutter speeds.

The ONLY time I use ANY setting other than ƒ/3.3 is if the scene is extremely bright, then I may go down to, ƒ/4 or 4.5. A very rare occurance as even the brightest day rarely exceeds 1/2000th second. (if the camera thinks it needs a faster shutter speed, the settings at the bottom will turn red).

Shooting this way will give you much better results - although the FZ200 may do even better because it's ƒ/2.8 is an even larger opening, so less diffraction.

This will not be found in photograpy books because it applies only to small sensor, "P&S" cameras and the authors in 99.9% of books, are thinking of 35mm size sensors.

Hello Erik.

Tack så mycket !

Thank's for the thorough description and comments ! I'll start looking at availability and prices. I'm personally so old fashioned that I still like to buy in real shops:-(  ,although the TZ25 for instance was ordered from Amazon (GB) by my wife , who is using Amazon reasonably much. (So possibly it will be again ordered from Amazon, which for us is the easiest and most reliable "web shop")

It's nice to hear that I'm not the only one who likes to use "as fast as possible" shutter time        (Also when I go out with my DSLR I normally use T, and the shortest possibly time.)

Still this week on summer holiday :-), so perhaps I'll go over to Tallinn at the end of the week to take some more pictures, IF there is not storm over the gulf of Finland (a "40 % risk" says the forecast)

best regards
