how are these compared to O-tang 4President 70mm 83a?

These are straight generic plain wheels. No special formulas have gone into the urithane. You can't compare them to very specific wheels because, odd are, if the person wants a very specific wheel, they won't get plain ol' generic ones. These are big, heavy, and bouncy. They roll over sticks but they don't go fast or slide well.Whatever you've read that is the difference physically (size and duro) is different. As far as ride, o-tang will be smoother, respond better, and last longer because they're name means it. But, if you're just after a cheap wheel, these do just fine.

These wheels suck. They are extremely slow. If you are into downhill riding these are not the wheel for you.

The extra stop is amazing... 70mm frames a head and shoulders from 10 feet or so... Works great with my lighting set up and excels in low light... If you want tighter shots from longer distances, the 105 would be the pick! Most portrait photographers prefer 85mm to 105mm- the f/4 just may not give you the background blur you may want... the 70mm-200M f/2.8 L IS II is another awesome choice...

No comparison. Ability to go to F1.4 makes the depth of field control so much better. These two lens are in completely different class.

To my understanding it is usually believed that 2470 is a better version than this one in the same focal length range. But there are other things to consider. How important is it for you to have the extra versatility, that is, the focal length of 70 to 120? How much do you care about the lost of aperture range? (And that depends on what you plan to shoot most often.) How important is the price difference to you? And weight differs, too. Actually, I envy the newest 750 model so much! lol. It certainly deserves good lenses.

Can't believe nobody took this on yet. I don't have all of these lenses below, but This list should get you started. FA 50mm 1.4 All purpose, fast, handy lens of good quality and respectable optical performance without paying too much: FA Limited 77mm f/1.8 Possibly a bit longer in the focal length than you would want permanently attached, but this is regarded as one of the best in-production lenses for the platform. FA* (Star) 85mm f/1.4 Impossible to find for a reasonable price anywhere, but this is also widely regarded as one of the best lenses ever made for the platform. FA Limited 43mm f/1.9 Hard to find for a reasonable price, a lot of folks swear by these lenses in the same vein as the 77mm. Not-so-much-sleeper primes include the FA 40mm and 70mm limited pancake lenses. They stop down to f/2.8 and have fast a/f and good image quality. If I were on a budget, it'd be between the 40mm and the 50mm. The 77mm is an eventual acquisition you pick up after some time.

i have both, i prefer the image quiality of the 85 F1.4, the 50mm is a little bit overexposed.Both have similar construction quality and USM autofocus system, but after 4 year of normal use the barrel system of the autofocus mechanims in the 50mm got deformed and stop to work.

Yes, much better. Better optics, better sharpness and color transmission, better weather sealing. Heavier, and more conspicuous. You might consider the 100-400 IS L lens. I switched from that because I got tired of carrying it around. Which is a problem with a 400 mm IS prime. Good luck. JWK

It is all about quality. The L glass will deliver you a very well controled CA, good quality in the edges and a wonderful color retention. The 50mm f/1.4 is good and if you dont require the state of the art you will be good with that.

For the extra $100, the G10 has 3" LCD 460Kp vs 2.5" 230Kp and lens 28-140 vs 33-133 also full PASM modes. All would be important to me. Many post attest to how much owner enjoy G10. G10 significantly larger 109x78x46 vs 97x62x28. You can tell I am comparing these 2 also. Go for the G10.

I have owned the 17-40L. It's a good lens. Its advantage over the 24-105 is only in the FL 17-24mm. For folks whose main interest is wide angle landscape images, the 17-40 has that advantage. In all other respects, I think the 24-105 wind, hands down. Its sharpness and detail is at least the equal of the 17-40, and of course it has the typical Canon L lens colors and contrast (all good). I really like the reach, out to 105mm, of the 24-105. Its weight, length, and balance are excellent for a lens of this focal length. It has become my favorite lens for the Canon 70D.

You mean the Tamron 18-300mm VC lens compare to 18-270mm lens. In my opinion the 18-300mm VC is a better lens for the price

Yeah, I'd say their elements are in the same class. Both use ultra-low dispersion glass and produce superb images. I think the main difference is that the 17-55 has to use larger elements. Which increases the relative aperture and the price tag.

I don't have the 28mm 1.8 but borrowed it before my purchase of the 24mm 1.4. It's a very good lens that is much lighter and obviously cheaper than the 24 1.4. The advantage of the 24 is obviously the extra stop of light or so. The 24 also was somewhat sharper than the 28(to my eyes), especially stopped down equally. You can't go wrong with either. Just depends on your price point and needs.

I think the 50mm will give you a very thin dof and will be very soft at 1.8 I use mine at around 2.2 and above.

i have both of these lenses and i have to say both are extremely sharp even wide open. i've used the 135/2 more often than the 200/2.8 because i mainly used it as portrait and candid pics. i've enjoy both of these lenses personally and really preferred prime lens over zoom.

The contempporary version of sigma 17-70 has an upgraded array of optics, and is lighter compared to the initial version of Sigma´s 17-70, and more compatible with newer camera models ie canon60D. This is the reason beneath the price difference. I am quite happy with my choice. Lens performance is great, image sharpness is outstanding!

depends on your usage, i'd say the 35mm f1.8g because its a better all rounder and is a lot sharper than the 55-200 ( i have both of these ) the 35mm is great for indoors i chose the 35mm 1.8 over the 50mm 1.8 because its wider. The build quality is not that great on the 55-200 and the vr motor gives a noise also the focusing speed is slow on the 55-200mm
