About canon 600D, about shifting lens. . . How much is 600D now? Do you have any bad comments about the machine? How much is it with a zoom lens?

600D fuselage, a little over 5000. I've never used a shift lens. You can learn about it online and ask the person who asked you to use the shift lens why. The effect of axis offset seems to be that the depth of field is very shallow ... I am a civil engineering student and a photography enthusiast. I use 550D, 600D should be the same as him. With the flip screen and wireless flash function, you don't need wireless flash unless you still have n Canon flash. Suggestion: If there is no problem with funds, try to sell Nikon D90 with a higher price, which is energy-saving and convenient with a shoulder screen. Endurance 1000 or so, 600d 400 or so (without flash and viewfinder). White balance can be gradually adjusted in the form of color temperature, which is more professional. There are only a few fixed modes for the 600D. The D90 is a metal frame fuselage, and the 600D is plastic. The pixel gap can be ignored. Nikon's delay in improving pixels must have put the cost on the useful configuration. Nikon is not stupid, and good photos are no worse than those megapixels.

As for the lens, my suggestion is that you don't need to buy a lens. What you said about imaging 18 135 is good, but the biggest drawback is that there is no focus scale window, which is very impractical. For example, you can't focus in the dark (the body has flash-assisted focusing and infrared-assisted focusing, which is not easy to use). With the scale window, you can estimate the distance to keep clear, and 1855. It is recommended that a lens with a scale window should have at least a scale. In architecture, I think wide-angle lenses are used a lot, and shifting axes is a bit like a toy effect. To get that effect, you need to buy a special lens. It's not suitable, and moving the axis is also quite expensive (red circle 15000- 18000, non-red circle 9000- 13000), unless you can take it for commercial shooting. If you buy a Canon fuselage, I recommend 17-85. I don't know if there is any production stoppage. Even if you buy a second-hand color, it's better than 18 135 or 17-55 ... Nikon I don't know much about lenses, but the wide-angle lens for architecture is right. By the way, the axis-shifting lens should be designed for Quan Huafu, and the 600D lens can also be used, but its focal length is X 1.6, so it can't be said that there is no wide angle (the axis-shifting of the red circle is 17mm), but the wide angle loss is a lot.

Axis moving lens:

Canon ts-e17mm f/4l16000-18000

Canon TS-E 24mm f/3.5L II 14000 or so.

Canon TS-E 90mm f/2.8 14000 or so.

Canon TS-E 45mm f/2.8 9000 or so.

That's it. The lens with "L" after the maximum aperture value is a red circle lens.

Ah ... make some additions. Just today, I borrowed someone else's "new york University Photography Textbook" and saw a brief introduction of the shifting lens. The advantage of shifting axis when shooting buildings can eliminate linear distortion. What is linear distortion? That is, if you shoot a tall building with a wide angle, you will have a strong sense of perspective, that is, all the lines disappear at one point. Shifting the lens can eliminate this phenomenon, of course, if you can use it.
