Photozone: Most current NEX lenses are not good enough for the NEX-7!

Sigma 30mm is very good at its price, and out resolves the expensive CZ24 f1.8 in the centre, making it a superb value lens. This is tested on a Nex 7, which is a lot more demanding than a Nex 5N.
With around similar price as CZ24, you can buy a even sharper lens, not as wide though, which can maximise the Nex7 resolution. Try the Zeiss ZM 35 f2 or the Voigtlander 35mm f1.2 version II. Both are sharper in the centre than CZ24 on Nex7 body and sharper than CZ24 at the corners, but you can't tell much a difference on a Nex 5N body though.
Nex 7 is indeed picky with lenses, and hopefully Sony with create a new firmware which resolves the magenta corners issues like what Leica M9 firmware did.

Sold my CZ24mm after just 1 day as well. Lucky this lens is very limited in supply and thus didn't lose any money.
It pairs well with the Nex 5N though with the 16mp sensor, just that it can't maximise the resolution of Nex 7 as compared to some of the Leica and Voigtlander lenses I tested. I know there are many users of CZ24 who love their CZ24 and I believe good photographers who knows how to maximise it will be able to use it's sweet spot.
I also realised a weird thing. If you close the aperture to F22 and shoot at bright surface, I realised that there is a small circular spot near to bottom of the picture. Tested 2 sets of the CZ24 and they have the same results on the Nex 7. This does not happen with Voigtlander or Leica lenses, and not with the Sigma 30mm.
Maybe existing user with Nex 7 and CZ24 can test it and check if this happens.

Actually, given the planned obsolesce "principle", technology, while presumably advancing in appearance, is far cry from what it could have been. The incrementals are kept, on purpose, to a minimal, R&D dollars go into marketing and reverse engineering to make products last for shorter durations. Is it a wonder why some Russian and Japanese made lenses from decades ago seem to never break down? Those my friends, were machines that were built to last.
Today, you either have to purchase extended warranty or watch your consumer electronics either breakdown, or be bitten by the upgrade bug. All 3 ways, corporations win. The little guy. That's us. The self-assured knowledgeable consumer who really is another gear in the cog.

So Leicas, Voigtlanders & Sigmas are good for NEX 7? Considering Sigma are so much cheaper... LOL
I quite liked the Zeiss 35mm F2 Biogon on the NEX-7, but one problem was the minimum focus distance of 0.7m, which is over 2ft. Most of the Zeiss and Leica M-mount rangefinder lenses have this problem. Can't use it to say shoot food on the table, but close portraits are OK. The Zeiss 24mm 1.8 E-mount is an extremely versatile lens, being able to shoot as close as 0.16m or about 6 inches, almost macro distances. The CZ24mm 1.8 is as sharp as the 35mm Biogon in the corners when stopped down to about F5.6, which is why it is so versatile.

Same problem on the Zeiss Planar 50mm f1.7, minimum shooting distance is ard 0.6m. Still find the CZ 24mm f1.8 abit ex...

Contax G Carl Zeiss 45mm F2 has mfd of 50cm. I use it for my food shots all the time and even when wide open, it's absolutely sharp.
Use the metabones adapter and you can go much closer than that..... And yes, they are very sharp!!! Once upon a time, they were the sharpest in the world.
Use it with Hawk's or Kipon's adapter with helicoid (adjustable extension tube) and you can go closer than that. Guide is , the wider the lens, the closer the mfd. Anyway you would need an adapter for m lens for the nex, so might as well get one with helicoid.

In that case, I wonder why would pple get a 24MP sensor if the pix is going to post in fb anyway.. haha

care to elaborate? you mean IQ and DR? I would agree with you... good lenses for NEX system I would disagree, m4/3 lenses are maturing well NEX system need to catch up fast else ppl wont jump to this system only those using legacy MF lenses would consider NEX system.

The Sony autofocus NEX lenses are "good enough" for 95% of people and the proof is in the many beautiful pictures taken with them. M43 does have some autofocus lenses that are slightly sharper than the autofocus NEX equivalents, but unless you are a corner peeper or shoot in unusual conditions, either system is fine for most people. Personally, together with the A-mount lenses and adapted lenses, NEX is already there or further. More lenses is better, but its already fine. In adapting lenses, NEX has an advantage due to crop factor and peaking focus.

After using the Contax G90 with my Kipon adapter, I would proabably use a non-helicoid adapter for normal use and helecoid only for close shots. I find that these complex adapters are a bit fiddly and don't feel smooth and professional.
