|1.)||Buying an Exakta AF lens is probably the worst decision you can come to. Although being Sigma and Cosina rebadges, to me it seems they didn't even match the required quality and durability criteria to be sold under the OEM or other rebadgers' labels. I held a few used Exaktas in my hands and approx. 70% of them were mechanically either broken or totally creepy (I've tested a lot of used lenses - apart from Sigma a normal ratio will be at around 2-5% creep). The rest was still creepy by nature of the thing it seemed, leaving the impression of absolute bottom quality even amongst the relabelers.
Don't deal with Exaktas.
|2.)||Some statistical facts about production years: The Sigma lenses, which the Exaktas above are based on, were produced by Sigma starting from 1988 to 2001 in total, 4 or 5 of them were added in 1995. Only 3 lenses were added to the portfolio later than 1994 (AF 28-80mm f/3.5-5.6 Asph., AF 70-210mm f/4.0-5.6 and SAF 70-300mm). Of those 3 lenses 2 were discontinued by Sigma after 1998 (28-80mm f/3.5-5.6 Asph. and AF 70-210mm f/4.0-5.6), the third model was discontinued in 1998. The rest of the Sigma originals was only produced until 1995 or even earlier.
Again: This is statistics. Sigma might well have discontinued the models under the Sigma brand while continuing to deliver Exakta branded models to whomever owned the brand by that time (see next note). And there are no confirmed dates for the Cosinas available at all. Just from looking at the confirmed dates implicates, that Exakta rebadges were mostly produced from 1988 to the later mid 90's.
|3.)||This gets us to the ownership question: Exakta is a company with a long and great history, though the greatness was long gone, when Canon EOS was born. I'll only cover the Canon EOS relevant part here. Exakta ownership was registered by Exakta Foto AG Zurich, Switzerland from 1984 until 1995. According to the US IPO (Intellectual Property Office) Jos. Schneider Optische Werke GmbH (a.k.a. Schneider-Kreuznach) filed a registration in 1996, which was executed in 1999. The trademark itself was first registered to wholesalers Exakta Foto GmbH & Co. Vertriebs KG Berlin, Germany in 1995, before Schneider finally took over in 2001 as well (according to the USPTO (Patent & Trademark Office)). I'm not aware of any connections between Schneider and Exakta Foto wholesalers, but it's hard to find out anything there at all. The filing correspondent was the same in both cases, which doesn't mean too much.|
