Canon EF-S 18-135mm f/3.5-5.6 IS USM lens (已停產)
for my entry-level DSLR Canon EOS 1500D
Manufacturing location: Taiwan
Disadvantages:
- Variable aperture (f/3.5–5.6) – not ideal for low-light or professional portrait work.
- Not weather-sealed – less durable in harsh outdoor conditions.

Most important warning: Do not look at the sun or a bright light source through the lens or single-lens reflex camera.
Manual focus adjustments are not possible when the camera is off.
Attach the lens: align the lens's red or white index with the camera's index matching the same color
Red dot → for EF lenses
White square → for EF-S lenses
Once aligned, gently rotate the lens clockwise until it clicks into place.

On APS-C, the smaller sensor applies a crop factor (≈1.6× for Canon), so the lens behaves like a 29–216mm equivalent on full-frame. On a full-frame body, the same lens gives its true 18–135mm range.

On the Canon EOS 1500D, exposure compensation in Shutter Priority mode may appear ineffective because the camera automatically adjusts aperture to maintain correct exposure. If the lens reaches its aperture limits, compensation has no visible effect.
ISO Settings: If ISO is fixed, the camera has fewer options to adjust exposure. In Auto ISO, the camera may override compensation by adjusting ISO instead.
How to Make Exposure Compensation Work
- Use Aperture Priority (Av) or Program (P) Mode: These modes give the camera more flexibility to adjust shutter speed or aperture, so compensation is more effective.
- Enable Auto ISO: This allows the camera to adjust ISO when aperture limits are reached, making compensation visible. (咁點解唔自己調 ISO?)

In Python, there is no difference between using double quotes ("Samson") and single quotes ('Samson') when defining a string. Both represent the same type of string object.
print("Samson") # Output: Samson
print('Samson') # Output: Samson
In Python, __init__ is a special method used in classes. It’s often called the constructor, because it runs automatically whenever you create a new object (an instance) from that class.
In Python, class names are typically written with a capitalized first letter.
Class: A blueprint or template. It defines what attributes (data) and methods (behavior) its objects will have.
Object: A specific instance created from that class. Each object has its own data but follows the structure defined by the class.

I wish I could return
to the time when I knew nothing.
Even knowing the ending would never change,
I still longed for a little time
to escape and look away.
The single lie you told,
in just an instant,
turned the colorful days we had built
into monotonous black and white.
My eyes grew clouded,
and even everything I saw
lost its light.
But in truth, I lied too.
Shouting that it was for both our sakes,
I left behind an answer
opposite to my heart.
Convincing myself it was the right choice
to deceive myself.
If a time machine truly existed in this world,
if there were magic to erase everything,
I would wish for no memory to remain.
If we could meet again, that alone would be enough.
How many times I wished for that—
even now, I wish to fall in love with you once more.
Your helplessness always made me sad,
yet gave me a happiness
I could never find anywhere else.
Compared to all the months and years we shared,
the ending was too abrupt,
disproportionate to what we had.
The future we sketched together,
I erased piece by piece.
And each time, I wondered—
if another future had existed,
would we be laughing together now?
Such thoughts linger endlessly.
Even if a time machine truly existed,
I could never erase everything.
Not the days we loved so deeply.
If there was love,
then being bound together,
and being torn apart,
all held meaning.
So that someday,
on the day I fall into my final love,
I can say with all my heart:
“It was wonderful to meet you.”
And let this goodbye
be one I can accept.
Next time, I will never
let go of someone’s precious hand.
I hope that someday I’ll understand—
this was a love
that taught me what mattered most.
A journey I was meant to experience.
