12-42ez v 12-40

Despite the superior weatherproofing and wider aperture of 12-40, if they are used for similar pictures within normal parameters will there be a noticeable difference in a 9" x 13" print. I ask because I am tempted to get a 12-40 but I wonder if there would be an apparent difference when used in good light for landscape ( my usual genre ) and the cost would be quite sacrificial !
Real life experience rather than quoting MTF figures from magazine tests would be preferred😀

Re: 12-42ez v 12-40

I have used the Panasonic equivalents quite a lot, the 12-32 and 12-35, and IMHO for landscape in decent light the differences between the two at that print size will be invisible under the great majority of circumstances. I'm assuming use around f4.5 - 7.1.

That chimes with my impression ie with careful photography and printing the prints made with the 14-42 are very good. I did some 9" x 13" earlier today and I am very pleased with them. But I just wonder whether a top notch lens would make a difference.

Re: 12-42ez v 12-40

I have both. The 14-42 is used when I want a lightweight walkabout but the 12-40 is always there for more serious photography.

Thanks for reply.
Does the 12-40 make superior or sharper images under normal daylight lighting?
I understand there is waterproofing, wider maximum aperture and superior build quality but it is image quality in normal levels of daylight that interests me.

Re: 12-42ez v 12-40

I too have both lenses and even printing at A3+ the differences are only just about noticeable. It's the edge distortions that are the most noticeable on the 14-42 but DxO optics Pro soon takes care of that, and even that is only noticeable on buildings and other such straight lines.

Thanks for real world information.
I haven't had the nerve to try A3+ although I use A3+ to do 2 x 9" x 13".
I put my prints in frames to sell. I'll try 12" x 16" to putin 16" x 20" frames.
Cheers

Re: 12-42ez v 12-40

I've never done any serious comparisons between the two lenses so can't help on that one. The only time I've ever compared the 12-40 with anything else was with the 14-150. The difference in IQ was very marked and in consequence I seldom use the 14-150 now.

Thanks for reply.
In what way was the image quality different ? I would expect a 10x zoom to be deficient in some areas compared to a 3x zoom. For example I had two 5x Minolta and Sony zooms that were very sharp but had bad distortion at the wide end, one would not focus nearer than 5 ft. and one had bad fringing.

Re: 12-42ez v 12-40

General lack of IQ. 10x zooms will never be as good as a 3x, but the Panasonic FT 14-150 was a lot better, albeit much larger.

Yes. But what is general lack of IQ?

Got a secondhand 12-40 today. Perhaps a rash move but was tempted and I'm off to the Yorkshire Dales for a few days next week to take photos.

Thanks. I need to justify the cost with some really good prints. ��

I have both plus the 12-50

Standard zooms by Alf Branch, on Flickr

I find I use the 9-18 more and more for landscapes
