If you don't know what "TTL" is when using a flash, be sure to read about it before buying a flash. This is a completely different level of flash work. After that, you most likely will not want to take a flash with "manual" control. When buying, pay attention to the compatibility with the "shoe" on your Sony camera. There is some confusion at Metz with this, as there are two versions of this flash: with the old shoe and the new "multi-interface" (MI). Be sure to check this point with the seller. In principle, the problem can be solved for not very big money by buying an adapter, but an additional device on the camera shoe is still bad. More risk of breaking something, losing, etc. Yes, and additional costs for the adapter to anything. Also note that this version of the 44 AF-1 does not have HSS mode. In principle, it is not "vital", but if you need it, take a look at the Mecablitz 44 AF-2 version, or more powerful Mecablitz flashes, this mode is implemented there (if you are so sunk into Metz products). In general, the Mecablitz 44 AF-1 is a very good reliable flash, now I have it as a "workhorse", but over time I always want more: this flash is not very suitable for assembling a system. Now I would buy a Chinese Godox TT685S for about the same money, but much more "fancy": built-in wireless synchronizers with Sony flashes in both Master and Slave modes (Mecablitz 44 AF-1 is only Slave and only in one group A with flashes Sony), the ability to run through a radio synchronizer with full TTL support, HSS mode, a larger guide number (60), excellent quality (judging by the reviews on the forums) and a bunch of nice little things that are not in the Mecablitz 44AF-1.
