After looking at the Tamron 35mm f/2.8 Di III OSD M1:2, we will now examine the Tamron 24mm f/2.8 Di III OSD M1:2. This is a moderate ultra-wide angle lens that is typically used for purposes such as street photography or landscape photography.
|Optical construction||10 elements in 9 groups inc. 1x aspherical and 3x LD elements|
|Number of aperture blades||7 (rounded)|
|min. focus distance||0.12m (max. magnification 1:2)|
|Hood||petal-shaped (bayonet mount, supplied)|
|Other features||dust & moisture resistant|
It is essentially identical to its two in-house relatives, with the 20mm f/2.8 being the third one to join the family. The only things that set it apart are its optical design and its name. And at the very least, that’s a good thing in terms of how much it costs. It is one of the prime lenses with the lowest price point on the market, coming in at about 250 USD or EUR.
Tamron 24mm F/2.8 Di III OSD M1:2 Ultra-Wide Angle Lenses
You cannot reasonably anticipate receiving construction of a professional standard for this amount of money. The chassis is constructed with polymers of a standard quality that are mounted to a metal basis. Even though it functions well, the rubbery focus ring has a distinctly low-quality feel about it. Surprisingly, the lens contains certain seals that make it resistant to moisture; nevertheless, there is no mention of dust protection anywhere on the packaging.
During the focusing process, the length of the lens does not change; nevertheless, there is a tube inside the lens that moves. Due to the fact that this tube is rather deeply recessed by around 1.5 centimeters, it is not quite obvious why Tamron built the lens to be relatively lengthy. One thing that sets it apart from the 35mm f/2.8 is the lens hood, which is in the style of a flower petal and is identical to the one that comes with the Tamron 20mm f/2.8 Di III OSD M1:2.
A linear extension mechanism is utilized by the AF system. The autofocus (AF) speed is on the sluggish side, but at least it doesn’t make any noise, which is typical for this sort of focusing mechanism. It is not possible to say the same thing regarding the aperture mechanism. When the shutter is fully depressed, you will be able to hear the camera opening and closing the aperture as it performs focusing operations. This again gives the air of something that was done on the cheap.
As is customary, “by-wire” operation is used for manual focusing. The lens is notable for its ability to focus extremely close to the subject. It is able to focus down to an object magnification that is a maximum of 1:2. (hence the M1:2 in the lens name). It should not come as much of a surprise that an image stabilizer has not been included considering that the pricing is so low.
