Sigma 30 f2.8 for Nex V

Sigma 30 f2.8 for Nex V

I have noticed with some of my cameras (especially with the m4/3 ones) that sometimes I get a better sharper image if I use it in portrait format. Not all the time but with certain lens it is the case. I tried to replicate this phenomenon on the Nex using the 30 f2.8 but it seems not to matter. I get the exact same crispness in landscape and portrait mode. Glad about that because it does have me thinking when using my m4/3 cameras.

I like the blues I get from this lens. Not too intense and is true to how I saw it. Again I'm impressed by the sharpness and, thank God, no decentering with either the 30 or 19 f2.8 lenses. Tested and tried and they seem perfect.

I really like this image. Is it because of the rendering, the sharpness, the colour or the contrast? Well, it's because of all thos points. And, of course, it's in a 1:1 format.
But that's just me.

A great focal length (for me) to walk around town with. Suits me very well.
Here's hoping that Sigma bring out some more of the very good affordable lenses. I'm just wodering if Tamron will get into the market because it seems to be growing and surely there must be a market  since Sony can't seems to produce (or deliver) any really appealing lenses for this system.

Sigma 30 f2.8 for Nex I

Having just talked about the Sigma 19 f2.8 for Nex and being really impressed with it, I looked the pricing for the other lens they brought out, the 30 f2.8. At €200 I just couldn't resist. It really is a bargain at that price and since Sony have only the 30 macro on offer (which doesn't really attract me) I ordered it. If it's at all possible this lens is even better than the 19 f2.8, which I will show in the coming posts.
The images will be very similar to the ones taken with the 19 f2.8 because I wanted to do a comparison on the same subjects at the same time. I am really impressed with these two lenses.

This will be the last image from this lens for the present. The image in this post is a square crop from the image yesterday. Like I've stated in the past, I wish I could select the quare format with these cameras. It makes it easier to compose the photograph in the first place. Here's to hoping that Sony brings that in in the next firmware update, but I'm not holding my breath.

I think I'm going to enjoy using this lens on my landscaping trips. Just seems to produce the type of image that I like.

I like the colours, I like the contrast and I like the sharpness. I can't fault this lens at all.
Remember, all these images were taken on the Nex-5N which is a fine camera. It might be different on the Nex-7 with it's 24MP sensor but I doubt it. I think I'll try it out one day but I tend to keep the 18-55 kit lens on that. I am also waiting on the 55-210 for that camera. I was disappointed by the colour shift you get with the Nex-7 with RF lenses but it's something we have to live with. The Nex-5N does a fine job though and I can't complain there either.

I think the Sigma lenses on the Canon mount are so bad (apart from one or two lenses) because they are reversed engineered. That is why you should always test the lenses for decentering and general sharpness at all focal lengths and apertures. Sample variance is widespread and in the end I gave up on them. From what I have seen the Sigmas do a lot better on the Nikon mount and the success rate was higher for those buyers.
Saying that I don't think it gets much better than this 19 f2.8 on the Sony E mount. Sharpness is great and the focal length suits me fine for my wide angle work. I don't think I really need anything much wider than this normally.

The lens is not exactly a pancake but it's not all that big either. I always thought that the Sigma lenses worked better on the Nikon mount and now I know they work pretty well on the Nex mount too. Hmmm...I wonder what they`re like on the m4/3 mount. But then again I've got the Oly 17 f2.8 and the Panasonic 20 f1.7 and the PL 25 f1.4. So I don't think I need them for that mount but Sony is lacking in this area and I'm glad Sigma decided to bring this one out.
