Should I get Apple USB C to headphone jack or an Aukey pb-y59 5000mah USB C powerbank? It will be jacks to use my iPhone to speaker via AUX cable but I hope to upgrade and get a Sennheizer HDB 630 headphone when I have the money some day and it has USB C connection which won’t make use of the adaptor much later, my iPhone 15 6.1 inch often run out of battery when I go out because I take a lot photo but power bank seem to fail quick, this one I found at an authorised Apple Store I can use a gift card to cut its price nearly in half or completely buy the headphone adaptor with just spend a bit more, which one should I get or should I get wireless powerbank which overheat often as I checked the review?

Can anyone show the with and without the lens stabilisation turn on and in combination to the digital stabilisation? is it worth to get over the Sigma 20-200mm which doesn’t have lens stabilisation?

DNG is now the official recognised raw format and people say it’s better for compatibility, Sigma BF shoot it, but does it really needed and better when the majority of software to edit raw support your camera propriety format likely? In what case you need and can only use DNG and make the Sigma BF better than any other camera?
