Looking for an item or items that are not in stock at B&H Photo? My gear pages can help, at least for the items that I test and recommend.
The gear page in-stock status is updated several times a day.
In this way, a quick visual scan tells you which lenses are available, or not. I provide this service for my readers, and of course I do hope that you will use the supplied links to buy, so that I get credit for the sale.
Bookmark the relevant gear page, and then check it each morning. Note that while B&H Photo offers an in-stock notification, it is often delayed, and first-come-first-notified, so frequently an item is sold-out by the time you hear of it.
In the screen shot below from the Nikon gear page, we can see that the Nikon 24/1.4G, 35/1.4G and 50/1.4G are out of stock (red price). The 35/1.8G DX and 50/1.2 AIS are in-stock (blue price).
