- Not heavy, the colors are quite natural, it takes great distances - a thrill
- It smears at the end, the tripod will fix it, but there is no way to always shoot with it
- Price. Focus and focus again! Lightweight and compact. Not bad assembled, better for example than a regular half-toss 1.8. It works well in general, and auto focus is normal, not as fast as usm, but enough.
- Picture. If up to 135 mm it is very good, you can shoot portraits, for example, then now it’s getting worse. Nothing helps with 200mm. Terrible soap, even if you cover the aperture to 16, 22 or even further, it seems like 32 is minimal there, it will not help. But it's not even about soap, but about chromatic aberrations, eerie purples that almost always appear. Even on not the most contrasting lines. Moreover, the size of these aberrations is simply huge. You can only shoot dark things against a dark background.
- Pretty good picture quality. Tight focus ring, spinning confidently and clearly. Focusing at long distances is stable even without a stabilizer - the right weight helps to keep it sharp. I rarely rub. Large range of focal lengths. HA do not appear often. Iron bayonet. And all this at a great price.
- Some play at the front. HA on long-range focal lengths in the sun (visible only with crop). Washes, nevertheless, quite a lot. Weak aperture, but these are the features of this class. At night or in low light, steady hands and high ISO are needed. Still, I would not refuse a stabilizer, but these are the costs of the price category.
- Decent construction, much better than 18-55, bayonet mount and outer metal tube, minimum backlash. Sharp picture even when viewed pixel-by-pixel with 50D. Parfocal! Low price
- Slow autofocus, strong chrome. aberrations at the long end, no IS
