🎙️ Your 50mm lens isn't really a 50mm lens — and once you know why, you'll never buy a lens with the wrong expectations again.
In this episode Rick explains crop factor in plain English. No maths degree required. If you've ever wondered why your lens doesn't seem to do what the numbers on the barrel suggest, this one's for you.
What's Covered
●        🎞️ What a full-frame sensor actually is, and where the name comes from
●        📷 What a crop sensor is, and how to spot one on your own camera
●        🔢 What the crop factor number means, and how to work it out
●        📐 Why your 50mm lens behaves like a 75mm lens on most beginner cameras
●        🛒 What to check before you buy your next lens
●        🌙 Whether crop factor genuinely affects image quality
●        📱 How this applies if you're shooting on a phone

🎯 Your kit lens has something printed on the barrel. 18-55mm f/3.5-5.6. Confident. Specific. And absolutely meaningless — unless you know what any of it means. This episode fixes that.
In episode 239 of the Photography Explained Podcast, I explain every number and letter on your kit lens barrel. In plain English. Without the irrelevant detail. Including why the aperture numbering system is completely backwards — and why whoever invented it clearly did not consult anyone who was actually learning photography at the time.
In this episode:
●       📏 Tip 1: 18-55mm — the focal length range. What wide angle means. What the longer end does. Why the zoom ring is your best friend.
●       📷 Tip 2: f/3.5-5.6 — the aperture range. What aperture actually is. Why the numbers seem backwards (and they are). What maximum aperture means.
●       🔄 Tip 3: Why the aperture changes as you zoom — variable aperture explained, what a stop of light is, and why your kit lens is actually being very sensible.
●       🌟 Tip 4: What aperture does to your photos — depth of sharpness in practice, a birthday party in low light, and the two things you need to know about f/3.5 and f/5.6.
●       🔤 Tip 5: USM, STM, IS, and Roman numerals — what all those letters mean and why none of it is random.

There is a LOT of camera gear out there. Bodies, lenses, bags, tripods, filters, memory cards, drones, studio lights — and it can feel like you need to spend thousands of pounds before you've earned the right to call yourself a photographer. You don't. Not even close. In this episode I cut through all of it and tell you exactly what a beginner photographer actually needs, what can wait, and what you can safely ignore entirely. 📷
In this episode we cover:
●        📷 Tip 1 — The camera body: why it matters less than you think
●        🔭 Tip 2 — The lens: this is where your money should actually go
●        📐 Tip 3 — The tripod: do you actually need one, and when?
●        💾 Tip 4 — Memory cards: the unsung essential nobody talks about
●        🔋 Tip 5 — Batteries: no battery, no photos — it really is that simple
●        🔵 Tip 6 — Filters: mostly not for beginners (with one exception)
●        🔆 Tip 7 — Lens hoods: the most underrated bit of kit you own
●        🔵 Tip 8 — Lens caps: free, essential, and easily overlooked
●        🎒 Tip 9 — The camera bag: carry what you actually use, nothing else
●        🚫 Tip 10 — The gear you don't need yet: drones, studio lights, second bodies, super-zooms

🧹 Your camera gear is dirty. And dirty gear is quietly affecting your photos in ways you might not even notice — a smudge on the lens that softens everything, a speck of dust on the sensor that shows up in the same spot on every single sky you shoot. In this episode I cover exactly what to clean, how to clean it safely, and — probably most importantly — what not to do. Because the damage usually comes from cleaning too aggressively, not from leaving things alone.
In this episode:
•       📷 Tip 1 — How to clean your camera sensor, including what to do when the built-in cleaning function isn't enough
•       🔍 Tip 2 — How to clean your front lens element without causing scratches — and why the blower always goes first
•       📦 Tip 3 — The camera body: a five-minute job that's worth doing every time
•       🔋 Tip 4 — Contacts, straps and filters — the bits it's easy to skip
•       👜 Tip 5 — Why your camera bag needs cleaning too, and how grit transfers straight onto your gear
•       🧹 Tip 6 — The only camera cleaning kit you actually need

🎒 Did you know there are 31 types of camera bag? One of them is a sandwich bag. Yes, really.
I used to carry a massive bag full of gear to my local park. Waterproof zips and everything. For boats I never went on. Seven lenses. Four batteries. Two speedlites. Snacks for a week. I was 10 minutes from home.
The penny dropped in Delph Woods in Poole on 30th December 2016 at 15:37. I used one lens. I always used one lens. The rest came along for the ride and stayed in the bag.
Choosing a camera bag is three times harder than choosing a sandwich bag. Here's how to get it right.
🎙️ What's in this episode
🚫 Tip 1 — There is no perfect bag — and you might need more than one
✍️ Tip 2 — Be honest about what you actually need — write the list before you buy
🏔️ Tip 3 — Match the bag to the shoot — mountain vs 100 yards from the car
🗂️ Tip 4 — 31 types of camera bag — all listed in the blog post. One is a sandwich bag.
📏 Tip 5 — Size matters — but bigger is absolutely not better
🤝 Tip 6 — The right bag just feels right — almost like a friend
🥪 Tip 7 — The cheese and pickle sandwich rule — the only test you need
