For the second lens, the sun visor held firmly. And if the photographer doesn’t know about it, he may not notice it in the viewfinder, and when viewed on a large monitor, he then grabs his head. This was quite a major difficulty, because even the slightest rotation meant that the aperture came into engagement. The biggest problem during the whole testing was with the Laowa 12 mm F2.8 Zero-D sun visor, because it didn’t click (and that I tried) and it moved regularly. Focusing can therefore be very careful and can be conveniently refocused thanks to the distance and depth of field scale. They are a joy to work with sharpening rings, they have a good response and pleasant operation. This is a pity, at least half of which would allow for finer work, however, toys can also use intermediate values with a very fine shift, however, it is not possible to estimate the exact value of the aperture and there is no locking. For comparison, the light Sigma ART 14 mm F1.8 is twice as heavy and 4 cm longer.īoth glasses have a very similar construction, the aperture ring is next to the bayonet and its steps follow the entire aperture numbers. However, even these are reasonable values, which are simply taxes for better luminosity and shorter focus.
The Laowa 12 mm F2.8 Zero-D also has a very well-processed metal body, but in direct comparison it is more bulky with dimensions of 75 x 83 mm and a weight of 609 grams. Add to that the metal body and we have a really nice lens that almost fits in your pocket and is ideal for long trips. And at first glance, it will be smaller and lighter Laowa 14mm F4 Zero-D with dimensions 72.5 mm × 75 mm / 72.5 mm × 73 mm (Canon / Nikon) and weight 320/360 grams (Canon / Nikon). We will put both lenses against each other a bit – after all, they are also competitors and you will only want one of them for your SLR camera. In this way, one look is enough and there is no need for electronic helpers, which are offered by current mirrorless cameras.Ĭanon EF: 72,5 mm × 75 mm Nikon F: 72,5 mm × 73 mmĬanon EF & RF / Nikon AI & Z / Sony A / Pentax K / Sony E / L Mount And here comes the major advantage of these lenses – their modern competitors often lack scales with a focused distance and depth of field, from which you can easily bounce when focusing. Sharpening this way is much easier than constantly refocusing before each shot.
During shooting, there is usually no need to touch the focus at all, except in specific situations where the subject is close. It is basically necessary to set them to the hyperfocal distance once and then only to check the focusing ring when switching on.
#Pentax 67 manual manual
Lots of people are immediately discouraged, but in fact, wide-angle lenses with manual focus save the photographer a lot of work.
A small exception is the transmission of data on the position of the aperture ring, however, these are only the numbers F1, F2…, which do not indicate a specific value of the aperture and subsequently are not even stored in EXIF as an aperture. CZK 26,490.Ī fully manual lens not only has manual focus, but lacks optical image stabilization, and in this case (specifically with the Nikon D750) there is no communication between the lens and the body. Specifically, these are Laowa 14 mm F4 Zero-D and Laowa 12 mm F2.8 Zero-D wide for approx. We have two Laowa lenses – both fully manual, wide angle, with minimal distortion and for SLRs.
