Tamron SP 150-600mm f5-6.3 Di VC USD for $869 (C/N/A)

If you are not tempted by the latest generation Tamron 150-600mm in the previously mentioned Tamron Solar Eclipse offer for Canon, Nikon and Sony A systems, and you instead prefer the first generation of the lens, without any solar eclipse accessories…

… then you can get the new condition Tamron SP 150-600mm f/5-6.3 Di VC USD for $869 with free shipping in the Canon, Nikon and Sony A systems at B&H Photo (with 4% promotional rewards) and at Amazon by Amazon itself (limit 3 per mount per customer; 5% back for Prime members paying with Prime cards)…

If you want to use the first generation lens for solar eclipse purposes, you can always purchase the appropriate filters and glasses separately. Or Nikon shooters can get the ready-made bundle from B&H Photo (only freebie are the $5 glasses vs buying lens + filter separately).
