Help me pick a lens...

Decisions, decisions, decisions....

I'm trying to finalize my setup and need to decide which of these lenses to keep. These pics might not be present enough info to help you choose, but the weather is kinda blah and I really didn't have much else to work with. Any opinions, comments, and suggestions would be greatly appreciated.

I did a chimney shot @F8 (with 100% crops) and a wide open bokeh shot for each of the 3 lenses. I'll label them #1, #2, and #3 for now.

Chimney shot
#1


#2


#3



100% crop
#1


#2


#3


Bokeh shot
#1


#2


#3

I like the first one best. Colors and contrast are better than with #2 and #3, and bokeh as well. Seems to have the widest aperture too.

Will you tell us wich lenses they are?

I didn't want to influence the choices by naming the lenses just yet. I'll wait a little longer before revealing their identities.

kinda hard to compare different focal lengths and the exposure on #3 chimney seems off.

Colors pop more in #1 and I prefer the bokeh in #1 but I think that #2 might be a tad sharper on the chimney (looking at the rust on the band. But colors seem flat. Don't like the bokeh in #3, but it depends on what the background actually looks like.

I'll go with #1 as the best overall choice in terms of color and sharpness, although I do like the bokeh of #2 a little bit better. I'm curious myself as to what lenses they are.

#2 looks to be the sharpest in my opinion.

It's interesting to see how the perception of sharpness, color, etc. vary from person to person. Granted, these aren't the best pics to do a true comparison. Hopefully, I'll get out later this week when there's some sun and take better pics with different subjects.

Now to identify the lenses (they're all in my sig):

#1 is the Tamron-F 135mm/2.8

#2 SMC Super Tak 135mm/3.5

#3 Super Tak 105mm/2.8

Yes, that is interesting. My pick was #2, and I have the Super Takumar 135mm f3.5 version of that lens. I've always thought it was sharp and had nice bokeh. Though the contrast can be a little low, that is easy to correct in PP.

I know you have answered it, but I'll explain what i thought about it even prior to seeing your answer (I don't know much of these MF lenses anyways).

With the first set I picked #1, clearly sharper in F8 and thought #2 was the worst...looked at the wide open shots and was frankly stunned by the #2 image, WOW!...went back and thought at F8 we can say it's a toss up between #2 and #3, so being the loser at wide open and tied for second at F8 #3 is out.

#1 is the winner at F8, but that wideopen shot of #2 is incredible to my eyes....so, to me if I can only keep one, I'll choose #2 for it's wideopen performance.

Thanks for all the comments...

The reason I want to move some lenses out is so make room for something a bit longer, like maybe a 300mm to 500mm prime lens. I also see no need to duplicate focal lengths.

I was surprised at how lackluster the Super Tak 105mm was, especially since it's such a highly regarded lens. Either the lack of SMC coating is an issue or I haven't spent enough time with it to find the sweet spot. I think I'll spend a day shooting with just that lens, which is something I've already done with the other two. Here are some previous threads I started featuring the top 2 lenses shown here with some pretty decent shots from both of them.
