What is the difference between the 35mm 1.7 &amp; 35mm 1.7_C lenses?

Both lenses are a C-Mount and cost the exact same so if I had to guess it's just a listing error.

Even better. The 1.4 is rock solid compared to the flimsy 1.8, and slightly faster. Ten times as expensive, but may be worth it. If you're still thinking of adding a new zoom to your arsenal, look at the 24-105L, as well. It's pretty much a coin toss, as far as IQ, with the 24-70L, but it adds IS. So, it's one stop slower, but it gains about 3 stops due to the IS, so it's actually better for low-light than the "faster" lens. And longer, too.

75-300mm IS is the older version and it has been around ways back. The 70-300mm IS is the newest version which has newer technology building in. I had both of them. the 70-300mm seems like having better auto focus on my rebel xt than the older version. I guess that justified the $200 difference.

The real difference is the image stabilization (IS). The quality of the two lenses is very good so you just have to be really really steady or use a stand to work without the IS. Hope this helps

since the aperture (f) is the same for both, the difference is the zoom. the 75 starts magnified more and can zoom in more than a 50-250. so 75-300 starts closer to the object and ends farther

The main difference on the 24-70 2.8 will be the 24mm setting compared to the 35mm setting on the old lens. You can take a much wider shot with the new lens. In addition, the 24-70 is a "G" type lens which means there is no aperture ring on the lens. Aperture must be controlled through a compatible camera. The 24-70 2.8 is more expensive. The macro focusing gets a little closer on the 35-70 (.91ft) as opposed to 1.2 ft with the 24-70.

Sorry but I don't know much about the difference in lens. I have only owned these ones. The lens are a pretty decent size. Just by looking at the picture of the GR004's it seems like these ones may just be larger.

I agree with Aaron on the Nikkor 35mm f/1.8 lens. Beautiful results at the cheapest cost you could possibly ask for. I have the D5100 body as well, and after I got the 35mm lens, it didn't leave my camera for months!

The newer version with the C is the contemporary line of lens, sigma also came out with a art line. Basically it's much better then all of sigma previous lenses and some of the art line can even beat Canon's L glass at a fraction of cost. Quality control is also better so less bad apples make it pass inspection. Just read the reviews, you can't go wrong with a lens from the contemporary or art line.

Like Ali said, the crop factor makes the 35mm more like a traditional 50mm lens. The 35mm is by far a better everyday shooting lens compared to the 50mm. I have both and the 35mm stays on the camera 85% of the time.

There is at least one good comparison of the two lenses on youtube. Check out the videos and determine for yourself which lens fits your needs better. The f/1.4 is my first non-L lens; the add'l cost and weight made the f/1.2 less of a good fit for me.

The one I bought was a77mm (C). I'm pleased with it's performance using it primarily to protect an expensive lens from wind-blown desert sand. If you Google around you can find info and test results where it did quite nicely. Try http://www.lenstip.com/113.4-article-UV_filters_test_Description_of_the_results_and_summary.html

I would recommend 23mm 1.4. The 35mm is a great lens, but 23mm is more useful as general purpose, also AF is faster and quieter. If you are not willing to spend for 23mm's cost, then 35mm 1.4 is next choice. Compare to 23mm 1.4, the AF of 35mm is slower, noisier. Also, 35mm is too narrow as general purpose while it's too short for portraits in my taste. I think 23mm 1.4 and 56mm 1.2 are great lenses to have, if you can afford them both.

f 1.4. You can take photos in lower light than the 1.8. Just an FYI, if I had to do it again, I would have bought a 35 mm 1.4 instead of the 50 mm.

The A33 isn't much of an upgrade to the A350. The A55 is, but do you *really* need the extra features? I doubt it. You might be better saving for the A77 which is due to be announced in the New Year. As far as lenses is concerned, if you have any Sigma lenses then these will need to go back to Sigma for re-chipping. All current Sigma lenses are incompatible with the A33/55 (and probably A77). If buying new Sigma lenses, then the box has a new sticker showing that is has been updated. Any other lens that works on the A350, works on the A33/55.

The most important difference is the lense 34X. The rest, both cameras are fine. Ral

Thanks for the info. I figured that out , finally. Don't know who gave me the misinformation about exchanging lenses, but I purchased the K-7 with the proper lens. Thanks again.
