Sigma 150-600mm vs Sony FE 70-300mm f/4.5-5.6 G OSS

This will be the hardest test for image quality in the middle of the lenses projected image. Firstly, add 150 millimeter and f5. The lenses pretty sha...

It extends when zoomed, and includes a lock switch so you can prevent the barrel from creeping out inadvertently when the lens is hanging downward. A reversible lens hood is included.

With the Nikon D3200 and Sigma 150-600mm, I often used the 600mm end. It's my personal sweet spot and I still have to sneak up on the birds. The problem with the 600mm end is with a maximum aperture of f/6.3, the autofocus system was not always reliable even with proper settings and back button focus

This is a good lens overall. Price is a bit high when compared to versions for other mounts and manufacturers, some of which are definitely superior to this lens. It is light and for the size I found balances well on an a7 series body. Nothing groundbreaking, but its the only option really for a 'travel' size zoom in the Sony lineup

The reason I upgraded was because I loved the 400mm reach and got addicted to it, and figured 600 was better than 400, right?? I will say that this is quite a bit bigger and heavier than the 100-400mm version (twice the weight). Your forearm WILL get tired of you handhold this for too long, but it’s bearable. The autofocus on this is a little slower than the 100-400mm, and it seems to hunt more - but it’s possible it’s because the extra reach compresses the scene more (that’s just a guess, I don’t know if that’s actually how it works). Costwise it’s not much more than the 100-400, so I would base your decision on whether you’re okay with the extra size and weight

Little to no chromatic aberration. Sharp in bright light. Constant aperture. Cons: Size

All right is this good. Can you turn to the left a little? I need this reflection. Yeah yeah, I'm getting the bounce back right here, that's good! It'...

At 70mm f/4.5 it scores 3,848 lines per picture height on Imatest's standard center-weighted methodology, an exceptional result. Performance is very even across the frame, with the mid parts and edges bettering 3,700 lines. When looking at photos from a high-resolution body like the 7R II we want to see 2,200 lines at a bare minimum

9-10m or 10m-infinity. Autofocus can go full auto, full manual, or auto with manual override. Many of my initial blown pics were because I had something set in the wrong place. One potentially awesome thing that I have not had time to try yet is that you can buy a $60 docking station that will let you burn custom settings and microfocus adjustments in to the lens as well as update its firmware

Autofocus speed is a little above average. Had a hand af lock button. For the cost, it would be nice to have a lower minimum f-stop, but we knew this coming in. The one downside is its a little heavy, which makes taking photos a little less enjoyable

The 2.8 aperture is great, but I shoot in forests frequently and 2.8 isn't really going to be a huge game changer in those conditions especially with the M50.

The aperture is a little difficult to work with. but its cause its a full frame lens on a apsc sensor. And im loosing some light. But this is one of the best options for a telephoto lens on sonys emount cameras

The Sport is supposedly more ruggedly built and better sealed - but that doesn't matter if the lens is too heavy for me to want to carry in the first place. And You can literally buy two Contemporary lenses for the price of one Sport.

One key advantage most mirrorless cameras have over DSLR's is light weight. You lose some of this when you go full-frame. The A6000 (which I also own) and the A6300 are great small cameras systems and I hope Sony will continue to develop more compact and high-quality APS-C lenses.
