CZ 16-80mm Adobe Profile

Posted on By

Continuing to make profiles when time permits, here is a reasonably detailed profile for the Sony DT 16-80mm f/3.5-4.5 ZA Carl Zeiss zoom (2007) created using the Sony Alpha 550 14.2 megapixel camera using Manual Focus Check Live View at 14X to set the lens focus and ensure the chart is positioned to use 100% of the frame.
http://www.photoclubalpha.com/DSLR-A550 (DT 16-80mm F3.5-4.5 ZA) – RAW.lcp
Right click to download this 56Kb file which should be placed in the Lens Profiles/1.0/Sony folder of the directory on your computer which holds Adobe Lens Profiles.
This profile has been created at full aperture and f/8-f/11 depending on focal length, at 16mm, 24mm, 35mm, 50mm and 80mm focal lengths and involved 90 raw captures.
It is possible in ACR/Lightroom to use profiles which are not created on your own camera type. This profile can be applied to any APS-C Sony or Minolta camera using the 16-80mm lens; because the A550 is currently the highest resolution body, the CA data gathered is more accurate than would be possible using a lower resolution body but may need a saved adjustment in defaults. Individual lenses differ slightly and may also need adjustments.
I have checked the operation of the profile on files from A100, A700, A200, A380, A350 and A550 and it’s very effective in removing CA. Illumination is much improved at 80mm (notably). You may prefer to turn the geometric correction down to zero (off) when the angle of view matters more than perfect straight lines – and also, where people are in the shot near the edges at 16mm. The distortion of the lens is optimised to lessen ‘stretched faces’ at the ends and corners of the shot, applying the profile removes this slight barrel distortion and does not improve groups. It’s most useful for horizons, rooms, seascapes, and subjects where a good straight rendering is critical.
It has been suggest I should add a donation button for these profiles. By all means see our subscription page, there’s a downloadable PDF of the latest Photoworld magazine for $3. I could easily have zipped profiles and sold them in the same manner, but that is not why photoclubalpha is here; Adobe provide the software to do this free (OK, I know what the rest of their stuff cost me…) and profiles should be made public domain by creators.

ACR 6.2 and LR 3.2 RC released – for NEX

Posted on By

Adobe has announced the Lightroom 3.2 and Camera Raw 6.2 Release Candidates, available for immediate download on Adobe Labs. The updates extend raw file support to 12 new popular camera models including the Sony NEX-3 and NEX-5, Alpha 290 and 390; improve on several of the lens correction profiles introduced as part of the Lightroom 3 and Camera Raw 6.1 releases; and add over 50 new lens profiles to help photographers automatically correct for undesirable distortion and aberration effects.
But they let Sony down in a big way by only including the 18-55mm OSS lens for NEX, omitting the 16mm which must be very simple to profile (after all folks, there are only TWO officially available lenses for NEX right now – you found time to profile no fewer than 15 lenses for the Pentax AF645, for the benefit of all two dozen worldwide users of this outstandingly popular digital option…)

Fitting a Vectis 80-240mm to the NEX

Posted on By

OVER the past few days I’ve been looking at the NEX-5 and a range of lenses and optical systems. I’ve got adaptors for C-mount (16mm/TV/CCTV) lenses, Leica 39mm screw, Minolta MD and the LA-EA1 for Alpha A-mount. The NEX-5 has proved able to provide a surprisingly bright focusing image through a classic German microscope:

It also proved very competent with the Sigma 70-300mm f/4-5.6 OS lens, the adaptor providing power for the OS which is fully functional, and also for auto exposure, leaving only manual magnified focusing to tackle. Continue reading »

Tamron grey importers get €2m fine

Posted on By

TAMRON Europe GmbH, Cologne, Germany attains drastic 2 Mio € penalty verdict against Ruitenberg / Crown in the Netherlands for dealing with illegal imports (press release)

On June 30th 2010 the district court in Utrecht/Netherlands (file reference number 262876/HA ZA 09-458) rendered a verdict against Mr. H.P. Ruitenberg and 4 respective entities of the so-called Crown group in favour of Tamron Europe, Cologne, Germany.

After an extremely harsh and meticulous prosecution Tamron Europe`s lawyers succeeded in providing evidence that Mr Ruitenberg and several of his respective Crown companies violated the trademark rights of Tamron by dealing with illegally imported merchandise, which was not imported into the EU by or on behalf of Tamron. The court could be successfully convinced of the damaging impact to Tamron Europe`s business resulting from the illegal trade.

The verdict includes a penalty of €2,000,000 for non-compliance with an earlier verdict that Tamron obtained in its favour. Tamron Europe urgently suggests all retailers in Europe to purchase Tamron merchandise solely from unsuspicious and fully reliable sources, as the company will not hesitate to take similar drastic legal action against any kind of trade with illegally imported Tamron products.

Practical's NEX-5 verdict – 8/10

Posted on By

I was going to post this on our Forum for NEX originally. It’s not good form to launch into what may be seen as ‘rival’ publications or journalists, so it’s the kind of thing which is often kept to blog pages or forum discussion. But Practical Photography is one the best-selling, and most powerful, photo magazines in the world.
So, I copied my ramblings and moved them here, instead of putting them in a forum post where just a few hundred people would see them. Tens of thousands of visitors see Photoclubalpha’s main site articles, and I want this to be seen, because it matters.

New Alpha 290 and 390

Posted on By

Sony has announced two new cameras this morning – but it’s not an announcement which will have Alpha system users rushing to the cashpoint and queuing at Sony Style. The Alpha 290 and 390 are dumbed-down versions of the 230/380 with user interfaces partly borrowed from the NEX including the built-in Help Guide. The rear 2.7 inch Clear Photo LCD screeen does most of the work of communicating with the user.
