Great site for test, news and discussion about lenses

[Deleted member 20471]

A new Swedish web site, http://www.objektivtest.se/, have started. On this webpage it will be tests and discussion on lenses. They are using the MTF measuring equipment at Victor Hasselblad in Gothenburg (Göteborg).The writers on the site are Christian Nilsson, previous technical editor at the (now closed) magazine Foto and Per Nordlund, optical designer at Victor Hasselblad AB.

The site is in Swedish but Google Translate will work, https://translate.google.com/translate?sl=sv&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fwww.objektivtest.se%2F&edit-text=

The test that have been published in the Swedish Foto magazine by Christian Nilsson, have in IMHO been second to none. My full lens selection is based on these tests.

I use Photozone, good test for both full format and aps-c censored bodies.

Actually, it does look like a useful addition. Their Tamron 150-600 test seems to be the only site that tested it also on APS-C and not only FF. Because of the access to the Hasselblad test center, they probably have a larger facility than other places, since most (e.g. protozone) didn't test 600mm on APS-C due to the large distance to the test target required. Now, I hope the Canon 100-400 II comes.

They have started an international version of this site, http://www.lensfreaks.com/

Photozone is nearly dormant. They still haven't tested the Sigma 150-600s on anything and have tested the Tamron only on FF. They have posted very few tests in recent months.

DxO tested the Tamron150600mm on crop as well as FF. I have been waiting for someone to post the Tamron 150-600 MTFs on crop. Although it is pretty good at 600mm on FF, I couldn't use it on the 70D at 600mm as it was so soft and actually posted some iso122333 charts, which someone suggested were soft due to shake. But, this site shows the same thing - good on FF but good only from 150-300 on crop and very soft at 600mm. DxO graphs show the same behaviour. Sharpness on crop is the hallmark of the new 100-400mm II. It is even sharp at 560mm with the 1.4xTC attached. I am waiting for some MTFs to be published for the 100-400 II on the 7DII.

Sometimes they are a bit slow, it depends on lens availability in Australia (for Klaus who does Canon). And they can't do very long focal lengths for space reasons. Some tests are fast though.

Not really surprising, the tests on FF showed already an obvious drop from 500 to 600, suggesting that crop would be worse, and a 1.4x TC won't do any good. So, all in all, I think I'm happy with the 100-400 Mark II.
