The olympus 300mm f4 is an incredible lens. Loved it for all of the 6 weeks I owned it before selling all my kit and going full frame.
Still much lighter than a full frame 300m f4 though
Smiling at everyone buying mirrorless, I just picked up possibly a 40 year old Bronica ETRS medium format film camera system… bit of a bucket list thing, always wanted to have a play with medium format.
After about 13+ years I ventured back into the darkroom, really is quite refreshing being hands on with the hobby again.
Still something nice about working with B&W film.
I am hoping to buy a A6600 before the £150 cash back deal ends this Jan 2022 and I was going to buy the Tamron 17-70 f2.8.
How good is this combination of A6600 and sigma 18-50 !as I might consider this lens as it is cheaper than the Tamron ! ?
Just to let you know that e-infinity is selling the a6600 for £1,059 but maybe you're already getting a better price after cashback?
The Sigma 18-50 and a6600 is a match made in heaven as far as I'm concerned. It's a lovely compact size and very light.
The Tamron is quite a bit bigger and almost twice the weight but does have built in stabilisation while the Sigma doesn't. However, since the A6600 has IBIS, you don't need a lens with stabilization.
The Tamron (and Sony 16-55 which is also bigger than the Sigma but also no built in stabilisation) has better weather sealing whilst the Sigma has very basic weather protection.
The Tamron has a longer focal range of course giving you the full frame equivalent of 25.5mm to 105mm while the Sigma gives the equivalent of 27mm to 75mm, so your choice depends on how important that extra reach is to you.
Optically, I think the Sigma is superb and pretty good in low light with the a6600 at f2.8. If you want a light small zoom lens which is quite fast, has great optics and you don't mind slightly less focal reach at the long end, then you can't really go wrong with the Sigma 18-50. Hope this helps. Check out this comparison review.
