The consulting doctor help me with, I'm currently using a canon 550D, intends to purchase additional map for you, you have 2 options here:
Option 1: purchase lens fix 35 f2 of the canon
The second variant: Flash Metz 48 AF-1 for canon boy and try to add a little more to buy me the fix lens 50 f 1.8
Hic, many medical doctors to come without help, the bag itself too hichic

Of 2 found. Flash stood stronger and more importantly can bounce. Lens 50 mm taken portrait also.
Requested by your doctor? If you like wandering the street (35fix f2) then perhaps few people used lamps, if the portrait is at use of lights.
I have not received the help dc is because your doctor can't say requests for clarification. In brief comments on just my tops.
Wandering the streets of Hi, the vintage save the dates Kit lens 18-55 meet enough, no need to purchase additional lens 35 mm/f 2 for this category.
Portrait, Canon has 3 lens:
-50/f 1.8 is cheap, good image quality, but build bad and missing shots, hard light noise AF AF

Photo taken from 50/f 1.8 (ISO 100, f = 2.2)-50/f 1.4 USM ranks but value for money due to the large open gun 1.4, build, AF is fast, smooth, bright and lack indoor shooting good, bokeh than 50 f/1.8, contrast also better
-85 mm f/1.8 USM reviews are also on a par with 50 f/1.4. This Lens for beautiful bokeh because of long focal length, fast AF and also build, smooth (USM which), but due to the narrow angle should take better indoor outdoor.
Not yet taken party, Conference, birthday, etc. in the House or take the evening to buy Flash later. Because the purchase of flash then you must update the knowledge take pictures with flash for portraits and souvenir photo. Play off-flash is all of DSLR, if less money then buy the ship as flash YN 450 (no TTL) 1tr price to Manual (little battery consuming vapors) is also very good.

Should you buy the lens capture to capture skills before, mastering aperture, ISO, speed, angle, direction of light, and then later purchase the following flash also, because flash player is to capture mode M range, other than take on board flash does not use Av mode even more.
Vote for option 2, must have lights I like heartburn.
Focal 35 temporarily in strips of tube kit is ok.
