❓ 8. Frequently Asked Questions
Common Camera Questions
Get answers to the most frequently asked questions about camera types, sensors, lenses, and features for different photography needs.
Q: DSLR or Mirrorless - which should I choose?
A:
Mirrorless for most people. They're smaller, lighter, have better video features, and represent the future of photography. Choose DSLR only if you specifically want an optical viewfinder or need the longest possible battery life.
Q: Is 12 megapixels enough or do I need 24+ megapixels?
A:
12-24 MP is perfect for most users. Unless you're printing very large photos (poster size) or cropping heavily, more megapixels just mean bigger files. Focus on sensor size and lens quality instead - they matter much more for image quality.
Q: Should I buy the camera body only or with a kit lens?
A:
Start with the kit lens if you're a beginner. Kit lenses (usually 18-55mm) are versatile and affordable. You can always upgrade to better lenses later as you learn what focal lengths you prefer. Body-only makes sense if you already know which specific lenses you want.
Q: Can smartphone cameras replace dedicated cameras?
A:
For casual use, yes. For serious photography, no. Smartphones are convenient and have improved dramatically, but dedicated cameras still offer better image quality, interchangeable lenses, manual controls, and superior low-light performance.
Q: How much should I budget for lenses?
A:
Budget at least as much for lenses as the camera body. Good lenses last longer than camera bodies and have more impact on image quality. Start with the kit lens, then add a 50mm f/1.8 prime lens (₹10,000-15,000) - it's affordable and produces beautiful results.
Q: Do I need 4K video recording?
A:
Yes, if you plan to record videos regularly. 4K is becoming standard and future-proofs your content. Even if you share in 1080p now, having 4K source material gives you more flexibility for cropping and editing. If you never record videos, it's not essential.
Q: What accessories do I need with a new camera?
A:
Essential: Memory card and spare battery. Nice to have: Camera bag, UV filter for lens protection, tripod for stable shots. Budget ₹5,000-10,000 for basic accessories. Avoid cheap tripods - they're more frustrating than helpful.
Common Mistakes to Avoid
- Choosing megapixels over sensor size - bigger sensor is more important
- Buying camera without considering lens costs - good lenses are expensive
- Getting DSLR when mirrorless would be better - mirrorless is the future
- Ignoring video features if you might record videos later
- Not checking lens availability for the camera system
Expert Tips
- For beginners: Start with kit lens, upgrade lenses later as you learn
- For travel: Consider weight - mirrorless cameras are much lighter
- For professionals: Invest in good lenses, they last longer than camera bodies
- For video: Check autofocus speed and 4K recording capabilities
