This is a commendable initiative you are undertaking, Anu.
I have three suggestions:
1. For "baby steps" you introduce many technical terms without explaining what they mean.
I suggest you link technical terms at least the first time you introduce them to a glossary. The following terms should be explained or defined DSLR, superzoom, optical zoom, sensor, RAW, MP, etc...
2. I'd be inclined to divide your initial blog into smaller digestible blogs with their own conclusions such as:
- Why Sensors are important (say)
- SuperZooms v DSLR (say)
- Know your DSLR - entry, mid, pro level
- Mirrorless cameras (pro & con)
- The main brands (inc Pentax)
- What to buy and why?
3. You could foreshadow what will appear in coming blogs and post links to other relevant beginner-enthusiast sites (including PF of course).
