Hi guys !

Could you all give me some suggestions ? I like to do DSLR filming and taking quality photos . So I've set my eyes on the Tamron AF 24-70mm f/2.8 SP Di USD VC as it has F2.8 and VC which means a lot to me . But I'm kinda worried as it's mainly for full-frame cameras and so, there will be a crop factor on my Canon 650D which technically means that it will have a focal length equivalent to 38-112mm . Earlier , I saw the Tamron SP AF 17-50mm f/2.8 XR Di-II VC LD Aspherical (IF) Lens which is like one-third the price of the 24-70, But the focal length to me, is kind of limited and I'm not sure if it will produce a substantial amount of quality . Also , I'm afraid that there are compatibility issues or auto-focusing issues for either of the lenses as it will be very annoying to have a slow-focusing lens. So could you please advise me on this and if you have any suggestions of other lenses that fit what I want , feel free to tell me :D

Thanks !

All these lenses are good, but do note that there might be noise during autofocusing when using these lenses. Have you consider the STM lenses such as the 18-135mm STM lenses from Canon, as far as I know, the STM lenses are designed with video taking in mind and focusing is practically noiseless.

Do note that autofocus is not a strength of Canon in video anyway. Almost all Canon video shooters use manual focus.

Man ... Should have asked for some advise before buying my camera . I thought the 18-135 was expensive so I went for the 18-55 kit instead :(

But which lens is better ? Is the 38-112mm equivalent focal length gonna be hard for me to take wide photos ?

How wide do you consider as wide (note: this is not a trick question, just very personal feel), I survive on my 18-55mm kit for quite a while... and for a long time, I use a 28mm f2.8 (which translate to 44.8mm for the crop camera) for my landscape and wide angle shots and I find it perfectly alright... although I do admit that I hope for something wider at times... So for me... 24-70mm lens (in term of wideness) is no problem at all... but I do not know about you, and only you can decide.

Get them from a specialist store instead. They tend to have ready stock and, if you are street smart, cheaper too.

They are called IT show for a reason :) Usually these shows only carry IT and some standard cameras with kit lens. And prices for these items are nothing attractive, apart from few exceptions and promotions. We have a lit of shops in the price guide sections. Call them, get e-quote and stock confirmation, much easier.

Hi!!!

I'm a 650d user too. Bought in Dec 12.
I got the 18-55 kit lens instead of the 18-135 kit cos I didn't know that there would be a difference. Silly me.
I then moved to 50mm 1.8 II for a month.
Then I decided to make the leap to a 24-70 as a needed the flexibility and a relatively wide aperture.

Narrowed down to the 3 big ones.

Canon 24-70 2.8 mkII
TAMRON 24-70 VC di usd SP
Sigma 24-70

Each has it's perks. In my opinion, Tamron lost out to the canon just very slightly.Note : This is only cos its is on the crop framed 650D. Its a different story when on the full frame cameras apparently But the image quality is very comparable on the 650d (according to the mtf charts). I bought the Tamron. I'm loving the image quality. I realized that it iq varies slightly at diff apertures and diff focal lengths. There is a sweet spot. Mine is at 40-50mm at f7.1. Buy the Tamron. Value for money.
$1700 with Kenko zeta protection filter @ SLRR.

The comparisons that I made and the mtf charts can be seen on the Tamron VC di 24-70 thread.

DRAWBACK. slower autofocus thru the viewfinder. But not so bad that you miss shots. But when you are on liveview, it takes about 2 and a half years to lock on to a subject.

Check out my street photos.

Thanks Norman ! But $1700 is way off my budget . I expected something like $1400 max cuz I don't have enough money :(
Is the VC a lot better than the IS on the 18-55 ? And do you have any tips on manual focus filming ?

I would think that the newer VC found in Tamron 24-70mm would be better than the IS found in the kit lens 18-55mm.

Anyway, if you are not in the rush to get a new lens, I would definitely advise you to save up and spend that 1700 on the Tamron lens, which is a fabulous lens.

The $1700 is inclusive of a $90 plus Kenko Zeta Filter. And a result of poor bargaining skills in March.

I am pretty sure you can push them to part with it for $1500 plus if cash is your only concern.

Aa for comparing it with it IS, I can't give you concrete data cos I didn't specifically do a comparison.

But I am comfy shooting handheld at even 1/8 on a 70mm zoom with the Tamron. The VC works well I would say.

As for movies, Ive never shot a single frame using the 650d. Can't help you there. Keep in mind the not so ideal autofocus response. I think it will be more of an issue when shooting movies.

get the 17-55 IS USM.

leave the 24-70s to full-frame users, unless you are ok with the 38mm equivalent wide end.

For video, it depends on your style. I prefer manual focus with primes. So smth like a 35/2 or 50/1.8 would b cheap n good.

If u die die need zoom, then any of those mentioned is fine. If u do pp and add audio on top of your footage, noisy af is not an issue already.

IIRC, the 17-55 cost less than the Tamron 24-70 VC.
IIRC ? Can help me find reliable sites ? I saw a lot of sites citing different prices . The Canon official website says that the 17-55 is sold at 1899 . Then how does the Tamron 17-50 fair with the Canon 17-55 ? Thanks :)
