Sharpness isn't everything tho.
You need the background to be a good deal farther away to get the nice smooth bookah
Even at the same aperture a 500f4 looks totally different, that and the colors, contrast and strangely even how it deals with highlights and shadows is noticeably different. I guess its to be expected with a lens costing 1/8 the price.
Then the autofocus is just much better on the higher end glass.
Regardless the lens is still nice for the price, but im looking forward to seeing how that tamron 150-600, IMO it could be the new budget super telephoto zoom
I'll definitelty be following your posts CoastalConn regarding the 150-600. I'm tempted to just roll the dice and pre-order myself. I'm gonna wait until the Xmas aftermath is over and evaluate my financial standing LOL.
Exactly, the sigma looks good to me as well... and the Tamron is just (at this point) an unknown. Coastalconn already has my respect from the work he produces and his willingness to share his experience and expertise so I'll be interested to see what his first-hand accounts are.
I have to say... I have the "new" Tamron 70-300 VC and it's a freakin awesome lens all around. I think both Sigma and Tamron are really stepping up to the plate with their latest offerings.
Many folks here seem to be gaga over this Tamron 150-600mm lens. I just checked the specs on that thing and it will not focus any closer than 8.86 feet. The Sigma 50-500mm, which I'm gaga over, focuses to 1.64 feet. If you're going to be a wildlife photographer I believe that should include ALL wildlife including insects and other critters up close. You won't be getting many good close ups of butterflies and other small wildlife from nearly nine feet away. After you've photographed your first 2,000 to 3,000 birds you will likely get somewhat bored and start looking around for other pretty things to photograph, at least I did. You will have very limited success with a lens that doesn't focus close unless you like to take distant shots then do a lot of cropping and editing. Having 500mm available that focuses to under 2 feet is about like carrying a super zoom and a macro lens at the same time. Part of the reason my Sigma 150-500mm got replaced was because it doesn't focus any closer than 7.22 feet. Hopefully that new Tamron focuses better in dim light than the Tamron I own. It refuses to focus anywhere except bright light. That's another issue I never have with Sigma lenses.
The sigma 50-500 has a variable mfd starting at 1meter (3.3 feet) at 50mm and ending at 3 meters At 500mm
It would be one hell of a macro lens if it focused to 1.63 feet at 500mm lol
Anyways there is no lenses out there at any price range that will do all great. Low min focusing distance and super telephotos dont go together great, for top quality wildlife or bug macro work a sigma 150 or tamron 180 is nice
