I'm a budding hobbyist and have been shooting on and off for around 5 months now. I just picked up a 55-250 and my photography bug bite has become infected
.
I've been editing my shots in photoshop (both outdoor natural light and indoor studio lighting) and have noticed that at 100% my pictures are kind of fuzzy. I have experimented with many different possibilities and I have no idea what I'm doing wrong or if its the lenses I have in my arsenal. I always shoot at 100 ISO, if I use my tripod I turn IS off, I use the timer when I can so I'm not touching the camera when it shoots and I've experimented with the different focal points and manual / auto focus.. I can't figure out what I'm doing wrong.
For my DIY studio I have 4 fluorescent daylight bulbs (2 75w and 2 100w) and I try to shoot in the late afternoon when I shoot outdoors.
Here is a pic of the diy setup. Any helpful suggestions to make these lenses work would be greatly appreciated. Otherwise direct me to the ones I should start saving for
