What are the main differences with Samyang SY75MFT-B 7.5mm f/3.5 Lens for Micro Four Thirds Are the same?
1761141
The lens is manufactured by Samyang with various labels that include Rokinon.

The two are supposed to be the same. In fact it's the same company, just two brand names...Not sure why there's this price difference.
1761143
Samyang SLR lenses are also branded as Rokinon, Bower, and so on.So, there's no difference between the lenses itself.

As reviewer Alan deLespinasse wrote on September 7, 2013"I just want to point out that this lens is sold under at least three different brand names: Samyang, Bower, and Rokinon." That has always been my understanding too.

I have been very pleased with my Samyang and use it on a 5d Classic, full frame. I wanted to use it on a FF to gain the benefits of the lens. I have both cropped and not when I have processed the images I have taken. It is a great lens and the price is right.

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!

I've tried both and I like the 24-70 far better. It is a sharper, faster lens.

The 18-55mm SAM II is made for APS-C sensors, so you will get a sensor crop (APS-C area on the full frame A7 at the correct focal length) or a lot of vignetting if you use the whole sensor. The 55-200mm should behave the same way. The 50mm 1.8 is made for APS-C. The 1.4 is made for full frame and will send light to the whole sensor.

Yes it's for 4/3, although you can use it on a micro 4/3 body with an adapter. You'll need the new Olympus OM-D E-M1 to use it properly though since it's a phase autofocus system only and won't work properly with the contrast focus system that regular micro 4/3 cameras use.But it's an awesome lense and can really recommend it. It's crispy sharp at full wide and full tele and with wide open aperture. It's really one heckuva lens!

I wasn't aware Sigma made this same lens in a "macro" version? Becarefull believing the discriptions as some "used" products are misrepresented. Any how, macro will allow for a shorter minimum focus distance. Good luck

The Zukio 70-300 f4.0-5.6 lens is a Four Thirds Lens for the Olympus E- DSLR Systems, while the Zukio 75-300 f4.8-6.7 is a Micro Four Thirds lens, a smaller and more compact lens for the Olympus OMD systems. Yes the 70-300 is faster, but it is bigger. I had that lens with my E-510, and while it works great with a tripod it's hard to handle without one. However, I can easily manage the 75-300 with my OM-D E-M5 camera and I get excellent results.Hope this helps.Ulf Wolf

The difference is the lens. You will have a gap of 20mm that you can't make up unless you buy the 55-250. That is why I bought this package. But keep in mind that even though the other one is cheaper, you eventually find that you will need the 55-250mm lens.

Yes, this lens is specifically designed for Micro four thirds, this is the second version of the lens and it is surprisingly sharp. However be warned that there is a four thirds model that will not mount on the OMD without an adapter.Be weary of any lens that is designed for four-thirds, the OMD lens mount is micro four thirds.

I have not had a chance to compare both but this sigma is the first non canon lens I have put in my bag. Have 6 different ones and the sigma is a great value. I have not regretted it.

The 24-70 is generally $300-400 more than the 17-55. There is no IS in the 24-70, and it weighs 2.1 lbs almost a pound more than the 17-55. Construction build is way better w/ the 24-70 and has a wee bit longer zoom. Those are probably the only advantages it has over the 17-55. IQ look almost identical from both lenses. I would go with 17-55 mainly for the IS and lower price.

Not much point in waiting. The 42.5/1.7 is a smaller lens that is lighter and slower(smaller max aperture). The image quality is also higher on this 42.5/1.2. The premium for fast glass that is higher quality is quite large so if you're looking for the best quality, this lens is currently the top performer for M43. If you're asking about if it's worth the price to you, that's a personal decision you will have to make yourself.

Both are excellent lenses with great IQ. 60mm is cheaper, weatherproof, macro, lighter, thinner, but works well for landscape and portrait too. 75 is amazing esp if you need F1.8, but honestly the 60mm is comparable. I have both..should sell one, but either is hard to part with. You really can't go wrong with either.

Yes! Any lens that is for Micro Four Thirds will work! Doesn't matter what brand.

Yes, it is a micro 4/3 lens... it is designated by M.Zuiko Digital on the lens face... "M" indicating micro, as a designator... for Olympus Zuiko Lenses.
