p.6 #1 · p.6 #1 · Tamron 35mm f/2.8 Di III OSD 1:2 Sharpness

A couple more new reviews. PC Mag shows that it's a very sharp lens and resolves more detail than the 35/1.8 except at 2.8, making it a great landscape lens.

https://www.pcmag.com/reviews/tamron-35mm-f28-di-iii-osd-m12

And another review mentioning the high level of sharpness across the frame.

Alright sports fans, would you pick the Samyang AF 35/2.8 or this Tamron for walkabout. Both fit my budget for this role and I don't need macro.

Neither?

What type of sports? They are both somewhat slow lenses (f/2.8) and the Tamron is fairly slow focus. The Samyang would probably have faster focus, but I could never find a centered one. I'm pretty confidant the Tamron would yield more sharpness and resolution. But for sports I'm not sure that's really a high priority.

Sorry, I was speaking colloquially.

Not sports but walkaround, street, casual photography.

I'm slower than usual today I guess.

Well, I've tried several Samyang, but never got one that I was happy with. It is a lot smaller, and it might focus faster. But the Tamron is kind of cube shaped, and really isn't unwieldy on the camera. I would vote for the Tamron as it is sharp from wide open. I don't remember the good corners on the Samyangs I tried being as good wide open.

Thank you, sir, that's the confirmation I needed. The Tamron looks to be an excellent deal and, at 210g, is well within my weight budget for "happy snaps".

I guess this shows how challenging it is to make U/WA lenses. Here are screen grabs from Photo Mechanic where you can see the Tamron 35/2.8 and Loxia 21/2.8 and GM 24/1.4. These are at f/11, so you would expect there wouldn't be much difference. This is straight out of camera JPEGs, with CORRECTIONS OFF in camera. Make sure you look at the full size image, it maybe a little hard to see on the smaller inline images I'm posting. The Loxia shot had a ND/CPL combo...but it was relatively calm when I took that shot. It's possible it would be slightly sharper at a faster shutter speed. The GM shot was fairly close in shutter speed.

The two knocks that seem to suppress any interest is that it is a slow lens, and the package (size, AF speed, etc.) I realize that after correction the gap will close, but I still find it impressive sans corrections.

Thanks all for the informative posts. Just a quick comment re: the zony 35/2.8. I picked up a beater for chump change with low expectations when I first went a7II. Center is very good wide open and sharp across the field by f4. Your zony samples look like you have a poor copy compared to mine.

best regards

Thanks, one of the big knocks on the Sony is that it is pretty sharp into the corners at wider apertures, but never improves much stopping down. Here's an old test that sort of shows that visually.

https://www.imaging-resource.com/lenses/sony/fe-35mm-f2.8-za-carl-zeiss-sonnar-t-sel35f28z/review/

Mine behaves that way, although it sounds like it could be better based on your feedback.

I'd be curious to see a near perfect copy to near perfect copy comparison. Guessing this may not be it, it's the closet 3rd party comparison I could find.

http://tiny.cc/v17tjz

The FE 35/2.8 came out so many years ago, it's tough finding tests on the newer Sony cameras (like the 42mp.)

At the end of the day, the best lens is a great copy you own. I'm glad you got a great copy, it seems like it's not always easy to make that happen.

Hi Tim, a common criticism of the Sony lenses is inconsistent performance. This seems to be true for the zony lenses too. At least the 35/2.8 is made in Japan, but seems there's still quite a variation in IQ.

cheers

Thanks Tim, for keeping this thread current.

It would be very interesting if the new Tamron 20mm comes close to this level of performance.

I haven't been tracking the 20 and 24 reviews much, but anecdotally, I believe their Achilles heel is distortion. The 35 has somewhat minor barrel, while the 20 and 24 have much higher levels and it eats away at some of the sharpness after you correct them.

Is there a good bokeh comparison between this lens and the other 35mm-ish options?

It would be great to have a mid-distance rendering comparison between Tamron 35/2.8, Sony 35/2.8 and Samyang 35/2.8.
We already have an idea of how the Sony and Samyang render and comparing them side by side to the new Tamron would be very useful.
Personally I don't own any of these lenses but if the Tamron's rendering is pleasant, it would be a consideration to me. The Sigma 45/2.8 has the most pleasant rendering for my taste but it's not 35mm.

I have a slightly de-centered Samyang 35/2.8 that was the best out of 5 that I bought (non were centered...and I mean you could see it at f/8.) I also have the FE 35/2.8 ZA but at least one person here believes is not a good copy. I'm not sure how much that will matter in a bokeh comparison though.

I can try to do a bokeh test, but this isn't my strong area. I tend to predominantly shoot landscapes where I'm not really working with, or focused on, bokeh.

I did try to do a CA/LoCA comparison between the CV 50/2 APO-Lanthar and the FE 55/2.8 ZA, which also gives an idea of bokeh.

https://www.fredmiranda.com/forum/topic/1625777/43#15107227

I could try to do something similar with these 3 lenses. I can try to do something this weekend, and if I miss the mark take another shot based on the feedback. Give me an idea of a subject you'd like to see if you have anything that can guide me in the right direction.

It's tough, so many good testers here, Fred....Phillip, Jannick, Bastian, Jordan........

Wow! you have all three lenses!

It should not matter if you have a slightly tilted copy. Comparing all three lenses with your subject at 3-4m distance should give us a good idea of how the focus transition zone behaves (smooth, nervous or in-between) and specular highlight rendering (outlining, color fringing, off-axis shape, inner structure, etc.)

Your 50/1.2 APO vs. 55/1.8 LoCA test was excellent.

How you tried AF-C or Eye-AF with the Tamron? I know focusing is not fast, but is it accurate?

If you're looking to set up a comparison (thanks!), there's a reasonable example here where the Sigma and Samyang 45's were compared:

https://www.fredmiranda.com/forum/topic/1625992/1

This is kind of a mid-far distance/transition bokeh comparison. Another comparison would be a person about waist-up, maybe from 5-6ft away (or similar size object). It's most instructive when there are particularly bright/dark areas of bokeh in the background from lights or foliage.

I will see what I can come up with over the weekend, as well as try AF-C and Eye AF. I've found AF-S to be accurate at least.

The FE 35/2.8 ZA was the first native lens I bought, late 2013 when I bought the a7R.

My dad was a press photographer in the 70's and 80's and then a commercial photographer. He was pretty floored when I showed him the WO performance of the Tamron.

The bokeh test will be interesting to see (for me as well.)

Any comparisons with this lens against the Loxia 35?
i just picked up a used copy of the loxia. its not on the level of the 21 or 50 i own so it might go back. its not horrible but not what i expected.
