Tamron 150-600 or Sigma C 150-600

I am thinking of using these mainly with my Canon 350 D camera, any thoughts on which is best?

Well I would say the Sigma is likely to be the better choice, simply because it has a better more sophisticated image stabilisation system with a panning mode. The Tamron VC system will not work while panning using a shutter speed below about 1/500s. Although many wildlife/BiF photographers will be quite happy using those shutter speeds, there are a lot of situations where it can be necessary to pan while using significantly lower shutter speeds. I am very often at shutter speeds of 1/160 or slower when shooting many aviation subjects. At those shutter speeds the only option for the Tamron is to turn the VC off. The Sigma has a panning mode (Mode 2) which allows the use of the OS at any shutter speeds while panning.

I never used the tamron but I love the Sigma.
I chose it over the tamron because of the extra features it adds. The 2 Custom switch settings you can use the dock to setup the focus speed and OS modes you like. The dock ability to adjust the lens if needed.
Plus I think it just looks better LOL

I've been using my Tammy for months now, and still absolutely love it. The image quality and function of the lens is flawless.

I've heard some good things about the Sigma, but to my eyes, the images from the Sigma just look a bit "off" somehow. Strange Bokeh or something. Can't quite put my finger on it. Perhaps it's just different than what I'm used to seeing from my Tammy.

Having said that, I'll never buy another Sigma lens. I've had to return every one of the five I've owned for QC problems. On the other hand, I've never had a bad experience with a Tamron or Tokina lens.

Some folks have great luck with Sigma. Just not me.

I'd go with Sigma. Extra features a plus. Even more significant is I'm in Australia and I can easily travel to the distributor / repair centre and my limited experience with them has been positive.

Heya,

Depends on how much you want to spend. For $1k, the Tamron is the best. At over $1k, the Sigma pulls ahead. It's that simple.

Also really depends on what you're shooting.

Take a peak in the lens sample threads and see what people are doing with the two different lenses.

Very best,

where do you pull your statements from?
Sounds like just out of thin air. I have yet to see anyone really go from the Sigma to the tamron but I have seen a bunch make the switch from the tamron to the sigma. So how do you get some fact the Tamron is better? They are both priced the same as well

Who are you talking to? There are seven posts above (including yours), only one has the Tamron. He gave the reasons he chose the Tamron, and did not say it was better (or worse) than the Sigma.

The only place is says the Tamron is best is if you are talking $1K. In the next line if you spend more then the Sigma is better.

Cost is the same!?! The Sigma is almost a grand more. So if you think they cost the same, either you are paying too much for the Tamron, or I want to know where you are buying the Sigma.

There are two Sigmas. One costs the same as the Tamron and that is the one people have been talking about here. The Sport version costs $1999.00 and the Contemporary costs $1089.00. The Tamron costs $1069.

Thank you troehr, I did not know there was a Contemporary model (only the Art). I guess that is what the "C" is for. Duh, on my part!

The OP is in the UK, where the difference in price between the Tamron and the SIGMA C (yes the Contemporary) is a bit over one hundred £

UK price of Tamron: £769.99-£869.00

In the US, the SIGMA is a no brainer with similar cost, and newer optics and better IS for the SIGMA. In the UK the playing field is a bit different.

If it were me, I'd be willing to spend the extra for the SIGMA OS.

The price will likely drop soon. It's already over £100 less from DigitalRev (in Hong Kong). Personally I'm waiting for the price to drop about £100 then pulling the trigger.

have you thought about upgrading your camera at all? both of these lenses aren't the fastest, so you're probably going to be wanting to use higher ISO

i'd look at a used 7D if i were you

I have owned both, sold the Tamron and later bought the Sigma 'C'. The Sigma is the better lens IMO, noticeable better AF in low contrast situations and the customization via the USB dock is very useful. No regrets whatsoever in changing from the Tammy to the Siggy 'C'.
