You don't need to label each drawtext, you just need to specify that both drawtexts are being applied on the "main" source. Everything that happens after the [in] tag is applied to the main source. You only need to label if you're using different filters, since you need to specify what is happening to each filter and when, and then how it relates to the main source. This command should work for you:

ffmpeg -threads 8 -i D:\imagesequence\dpx\brn_055.%04d.dpx -vf "[in]drawtext=fontsize=18:fontcolor=Green:fontfile='/Windows/Fonts/arial.ttf':text='shotcam':x=(w)/2:y=(h)-25, drawtext=fontsize=18:fontcolor=Green:fontfile='/Windows/Fonts/arial.ttf':text='Focal Length':x=(w)/1.2:y=(h)-25[out]" D:/imagesequence/dpx/final_with_text_mod_04.jpg
