[QUOTE="WayneF, post: 525868, member: 12496"] The D3300 spec chart in user manual (also about all Nikon DSLR models) specs the light meter range at 0-20 EV, specifying at ISO 100 with a f.1.4 lens. So I suppose a f/3.5 lens would be about 2.67 EV less range. P mode only has a somewhat narrow range where it works. The meter can work over a wider range, but not P mode. One reason is that P mode also uses a chart of the permissible values it can use in that range, and it won't go below EV 4 (at ISO 100). And if flash is used, P mode also limits the low end even more, and then even more at high ISO than at low ISO. So, if we buy a f/1.4 lens for flash, P mode will never use f/1.4 with flash, so possibly not the best mode for flash in dim light. But P mode can be of advantage for TTL BL fill flash in bright sun (P mode knows to accommodate Maximum flash sync speed, and will try to keep us out of HSS flash mode... where A or M mode doesn't, if HSS is allowed ... it needs our attention). I don't think the D3300 manual includes the chart, but here is a P mode chart from a D800 manual. For example, if ISO 100, if P mode chooses f/4, it will also say 1/60 second (from this chart). We should never confuse automation with intelligence. :) Just meaning, we may of course have reasons to choose other values, but P mode does not know them. :) And P mode won't go below EV 4 (at ISO 100). The D3300 P mode will be a similar idea (I don't know if the same exact values or not, but should be fairly close).
