While the 1.4x pz-af MC has 7 contacts on the body side.
Correct?
No answer?
Originally posted by selar I'm just saying that all TCs, be they Tamron, Sigma, Pentax, Kenko, are all superflous, unless you wish to save yourself the trouble of cropping in PP.
When the fact is that 14MP sensors and 10MP sensors outresolve nearly all of the lenses out there, IMHO, your spare change is better spent on buying better quality lenses (or paying off the mortgage, if you have one).
Well, you may be wrong and right at the same time...
You are right if the original lens doesn't outresolve the sensor.
You are wrong, however, if the original lens does indeed outresolve the sensor and if the TC is as good to only add magnification, no new flaws.
A 14.6 MP sensor needs a lens resolving at 200 lines/mm (100 Lp/mm). According to Zeiss, their very best SLR lenses resolve at 300 Lp/mm (Zeiss ZF series)!
So, there may be original lenses where a TC delivers full performance even with a 14.6 MP sensor and where
your "crop is equal" argument does not hold true!
According to first reviews, the DA* 200mm may be one such lens.
The DA 50-200mm on the other hand may be too soft to make a TC meaningful.
