Tamron 28-75 & 17-28 vs Sony 24-105 & prime lens

I have the 24-105 and it’s my favourite travel lens. I will also buy the Tamron 17-28 within the next 6 months to replace my Minolta 17-35 (used with LA-EA4 adaptor). This combo will work well for me. I don’t use UWA too often so the Tamron prices make more sense. For me personally prefer the Sony 24-105 over the Tamron 28-75 to cover that FL. I tend to alternate between Zoom and prime solutions depending on where I travel. For overseas trips I just take the 24-105 and the 55/1.8 whereas for trips in the UK I enjoy using Batis 25/40/85 and leave the Zoom at home. So for me the UWA Tamron Zoom is a perfect (and economical) solution to compliment the 24-105. Have considered Batis 18 but it’s pricey for a FL I would use the least.
 
"do you need a 28 mm F 2.8 lens?"

:

The same can be said about the Sony.

Do you need a 24mm f4 lens?

Also, if you need to go up to 105mm equivalent focal length with the Tamron, just take a few steps closer.

I've had this discussion on the A7iii Facebook page. When shooting landscapes, while the 4mm on the wide end isn't that much, one can lean back, the 30mm on the long end is. There are simply many a place where one can't step back or forward. It sounds easy but in many cases not doable.
 
So ALL 2.8 lenses are better than ALL F4 lenses?

No, I said "I will always prefer a lens with f2.8 over f4", that is not saying "ALL 2.8 lenses are better than ALL F4 lenses".

How about answering the question instead of diverting?

"If you compare the Tamron 28-75mm f2.8 lens on a body with IBIS, are you saying the Sony 24-105mm f4 lens has noticeably better stabilisation performance in the 28-75mm focal range?

Please post a link to a test that substantiates that claim?"

So you can't substantiate your comments?

"...aren't you forgetting the fact that OSS on the 24-105 F4 gives a significant advantage"

and

"The OSS easily gives a 2 stop advantage if not more"

and

"I don't think the shallow of DOF of 2.8 is really necessary or even desirable"

I don't care enough to do so.

Have a nice day!

Lol, I thought so.

You cared enough to post your reply to poipoipoi_2016, but when ask to substantiate yourself, you suddenly "don't care to do so".

Credibility comes into question if you can't substantiate your posts Corelli.

What you posted is clearly false and untrue, that's why you can't substantiate your claims.

"Have a nice day!" 😉

You obviously have more at stake in this than I do.

Think whatever you like.

Yeah I will,

I think anyone who can't substantiate their posts when challenged, has no credibility.

Yes. I am indeed quite incredible ;)
 
The OSS easily gives a 2 stop advantage if not more and in a museum I don't think the shallow of DOF of 2.8 is really necessary or even desirable.
To find the minimal shutter speed I can use, I did couple of tests.
For example I photographed with a shutter 0.5 seconds with a 85 mm F/1.8 lens and with 24-105 mm set to approximately to 85 mm.

My results are 10% good pictures with the 85 mm lens and 25% good pictures with 24-105 mm.

I do not know if it means 2 stops, but for me it is significant.

I will take the range of the Sony 24-105 over the extra stop or so of the Tamron with no hesitation. Love the lens. Only complaint might be the weight, but it is worth it.
Not to mention the autofocus is so much better on the Sony, at least on the instore demo Tamron I used. I was pretty keen on the Tamron, but it’s autofocus was way slower than than the Sony. That’s a pretty bug deal imo.
 
I wasn't that terribly unhappy with the kit 28-70, but wanted to move up a bit in quality. No gain in either the wide or tele end of the Tamron just gave me no reason to move to it. After getting the 24-105 I found the increase in sharpness and micro contrast was a great bonus, and REALLY love the extra range on both ends.
 
While what you say is true, aren't you forgetting the fact that OSS on the 24-105 F4 gives a significant advantage, particularly in museum where you are not allowed to use a tripod?

Lol,

If you compare the Tamron 28-75mm f2.8 lens on a body with IBIS, are you saying the Sony 24-105mm f4 lens has noticeably better stabilisation performance in the 28-75mm focal range?

Please post a link to a test that substantiates that claim?

Also, I will always prefer a lens with f2.8 over f4 any day of the week, and any other reasonable photographer would too. To argue otherwise is nonsense.

"lol"

anyway, got the 24-105 as well. the 28-75 is nice as im sure is the 17-28 but keep in mind theres a reason for these numbers. you always have a trade-off. thats why its not 24-70. pick your trade-offs. none of these are bad choices.

anyone saying you chose the lens due to its f number over anything else has no clue...

The Tamron AF speed and accuracy is fine. Here's a comparison test against the 2-3 times more expensive Sony 24-70 GM:


In comparison to the much more expensive GM lens, the Tamron is slightly slower (especially in lower light), but saying it's "way slower" is stretching it IMO.

My comment was purely based on my experience in store between the 24-70 GM, 24-105 G and 28-75 Tamron all on the same camera - A73.

The difference was enough for me to rule the Tamron out, it was that noticeable. The two Sony’s were about the same.... I dunno why but that’s how it was for me.

The video link I posted shows acceptable AF performance with the Tamron on an a73.
