As
zjacreman already said, the 19-35 is a Cosina design, which was sold in several variants:
Cosina 19-35mm 1:3.5-4.5 MC (KAR)
Cosina 19-35mm 1:3.5-4.5 MC (KAF) black and silver version
Phoenix MF 19-35mm 1_3.5-4.5 Zoom (KAR)
[caution: I once saw one on Ebay that had a front ring that said "Phoenix 19-35mm 1:3.5-4.5 AF Zoom" but the bayonet proved that it was MF]
Phoenix 19-35mm 1:3.5-4.5 AF Zoom (KAF) black and silver version
Promaster Spectrum 7 19-35mm 1:3.5-4.5 MC (KAR)
Promaster Spectrum 7 19-35mm 1:3.5-4.5 MC (KAF) black and silver version
MC Soligor Zoom 19-35mm 1:3.5-4.5 (KAR)
MC Soligor AF Zoom 19-35mm 1:3.5-4.5 (KAR)
[Again one that says AF on the front ring, but the bayonet shows a Ricoh pin instead of AF drive]
MC Soligor AF Zoom 19-35mm 1:3.5-4.5 (KAF)
Tokina AF 19-35mm 1:3.5-4.5 (KAF) 2 design variants
[not 100% sure if this is really the Cosina OEM lens]
Vivitar Series 1 19-35mm 1:3.5-4.5 Multi Coated (KAR)
Vivitar Series 1 19-35mm 1_3.5-4.5 MC Auto Focus Zoom (KAF) black and silver version
Alternatives for FF are:
smc Pentax-FAJ 1:4-5.6 18-35mm AL
Even wider:
HD Pentax-D FA 15-30mm F2.8 ED SDM WR (KAF3)
[the best option, if you can afford it]
Sigma Zoom 15-30mm 1:3.5-4.5 DG (KAF)
[quite rare, but relatively cheap <300 €]
Sigma 12-24mm 1:4.5-5.6 DG EX (KAF)
[The ultimate ultra-wide-angle-zoom for FF, rare and in most cases 500+ €]
