[Canon RF] Confused about Lens selection!!

[bb_13]

It depends. For most budget flashes, if you set your flash to manual mode in low power and the batteries are fresh, you may get 2/3 shots in a burst before the flash switches off to recycle. Practically that means that in a burst of 5 shots, the first 2 may be lit by flash and the balance 3, not. Generally speaking, you cannot reliably depend upon a cheap flash to support burst mode.

Manual mode as in? The flash will sync with camera right or I am misunderstanding something here, won't the external flash will work similar to on-camera pop-up flash?

Manual mode means you decide the power output of the flash (and the zoom setting if it has the feature). It does not do TTL exposure adjustment in this mode.

This mode works well in macro photography, especially if one is photographing a skittish insect that might fly off with the pre-flash that's required for TTL. Manual gives you accurate control on flash power.

Camera flashes have several modes, most of which control exactly when it pops off - earlier or later in the exposure giving the picture a very specific effect. These effects are not the glitzy glam sort but meant to exert control on the look of the image.

In all modes including manual, the flash will sync with the shutter release. Most of the modes take some input from the camera - the ambient light detected, shutter speed etc before giving the flash the signal to pop. All have some degree of automation. Of them "manual mode" allows most control by the user re the amount of power (read brightness) & spread, of the flash.

External flashes work much better than on-camera pop up flashes. Which is why pop-up flashes exist only on cheaper entry/intermediate level camera bodies. You will not see them on higher end camera bodies.  

A word of advice: if you are really interested in learning about flash, get online and find resources that teach you the whole thing systematically. Here, before you learn the basics, answers from different responders, will only confuse you.

Official Canon adapter is 7-8k I saw one guy selling no-brand adapter for 4k, that would be good option or I should opt for branded only?

I would recommend a branded one for peace of mind, and if you are planning to use the adapter for a long time.

Can you please suggest any YT video series or any website, resources etc if you have any.
