Ahoj! This is Zdenka. I bought a new camera. No. I'm actually talking about you.
So you bought a new camera or you had a camera for a while now
and you are thinking about getting another lens. So the questions you are
asking yourself is: what lens should I buy next and what is the best lens?
Well, those questions cannot be answered just like that. Lenses is topic of
today's video. Let's talk about them. What they can do? What makes them different
and what main questions you need to ask yourself to know which lens you need to
buy next? I've got a lot of visual examples of all the lenses here I have today.
And if we don't know each other yet, my name is Zdenka Darula. If you want to

are thinking about buying the next lens, there are five questions you need to ask
yourself. First of all, what are you going to be shooting? Fashion, glamour,
sports, nature, cars, indoors, exteriors, architecture. Are you gonna be doing
mostly photos or videos or both? The next question you should be asking is, are you
gonna be shooting in low-light conditions? Third question is, do you need
zoom or are you okay to move back and forth? Fourth question is, are you gonna be
shooting in tight spaces where it is quite narrow? And lastly how much money
do you have? I'll answer these questions at the end
of the video, so you get the practical example but now, let's look at these
lenses. They have different sizes. Some of them are quite small, others are quite
big. Most of the people know that they work
just like spyglass or binoculars so you can
just zoom in but it is a lot more than that. What makes lenses different from
each other is focal length, compression and depth of field. Quick example here.
I've got two different lenses here. Completely different. I'm gonna set them
both to 70 millimeters, I'll take photos with both of them and you will see that
they will look completely different.
What is focal length? Focal length is
measured in millimeters and it is the distance between optical center of the
lens and camera's sensor. So where is the optical center of the lens? Imagine two
rays of lights entering the lens so this is one, this is second. Where they
will cross eventually, that's where the optical center of the lens is. So this is
how the lenses are named. Not by how big they are. So for example this 150
millimeter lens. The focal length of this lens is 50 millimeters and it always
stays the same no matter which camera you use. But. You know there's always that
but. Depending on what camera body you use, the effective,
not the actual focal length I was talking about, the effective focal length
will change depending on the crop factor. DSLRs or full-frame cameras have no crop,
so they are assumed to be 1x. So 50 millimetres focal length is x1 50
millimetres focal length. Now some of the Nikon cameras have 1.5 x crop and some
of the Canon cameras have 1.6 times crop. Let me get this lens 24 to 105
millimeters. When I have it at its widest 24 millimeters when i zoom in all the
way, the lens gets narrower. The focal length change
and also compression in the image. Now it's time to talk about compression. What
is compression? It is how far the object looks. When I shoot with wide lens,
distance between objects look big. Foreground and background will be more
separated. But when I shoot with telephoto lens and I zoom in, the more I
zoom in, the more compression will happen. The closer the subject will look. So one
of the things to consider when you're buying your next lens is not only what
zoom you want on your lens but what compression you want in your image. Depth
of field is related to compression. So let's talk about that. What is depth of
field? The more you zoom in, the more depth of field, the more bokeh, the blurry
background we all want will happen. So depending on all those things what you
actually want to see in your images and video will help you decide on what lens
you want to buy next. Now though, let me go through all my lenses and explain
what I actually have and why I bought them. I use different lenses for
photography and video. Well, some of the lenses actually use for both. So let me
start with photography. When I got my DSLR, the first lens I got is 24 to 105
millimetres. It is more of a general lens. It's got nice width but also decent zoom.
I use it for street photography, weddings, group shots and shots in tighter space.
50 millimeters is the next lens I got which is excellent in low-light because
of this number. Aperture. The lower the number is the better it will be in
low-light and I actually made an entire video about this lens, I will link it in
the video description below so you can check it after this video. On this lens
there is no distortion which I'll talk about soon. So whatever your eye see
that is exactly what you get. 70 to 200 millimeters telephoto lens.
This is an expensive lens. It's got an amazing zoom beautiful bokeh, great in
low-light, stabilization feature on. I rarely have blurry shot with this one.
I actually almost never have a blurry shot. I absolutely love this lens. All of my
fashion, glamour, portrait photos are taken with this. Let's talk about video for
youtube. I just use this kit lens 15 to 45 millimeters with my mirrorless
cameras. Why? It is cheap and it has enough zoom I need. I also take all my
thumbnail photos with it. Let's look at distortion little bit. The wider
you go, the more fish eye effect you get. The lines on the side will get curvier
the wider you go. The smaller the center, the face for example will look. This
is 15 millimeters for comparison, this is 30 millimeters and this is 45
millimeters. I like the curvy look for YouTube so I use 15 millimeters. If you
want the professional look with straight lines, you need to go a little bit higher
like 30 millimeters for example. I also like to use 15 millimeters and this
telephoto 70 to 200 millimeters. I'm still missing one more lens and it's the
wide angle lens. I really would like to get one quite soon.
Once I win lottery and I think somewhere between 10 to 12 millimeters would be
nice. There is no lens, no Universal lens which solves all the problems. It's very
difficult for me to tell you exactly which lens you should be buying. Mainly
because I don't work in a store and I don't know exactly what everything is
right now on the market, what everything is there for sale. Choosing the next lens
for you will depend on all those factors I was talking about in today's video and
also on a budget. I truly hope this video gave you some
answers and gave you information about lenses. All the lenses I was mentioning
in today's video, all the products I was talking about in today's video is linked
