Hey, new member here. I've been reading several posts and have done countless hours of research and am stuck in deciding my next lens purchase. I'm hoping that the large amount of knowledge on this forum will be able to help me. I currently have low-grade gear and while I know I have room to grow as a photographer (who doesn't?), I see issues with my current lens. I'm using a Rebel T3i (600D) with:
Canon 18-55 IS II f3.5-5.6 (non-STM)
Super Takumar 55 f1.8
S-M-C Takumar 135 f3.5
The Super Takumar 55 1.8 is easily my sharpest lens, and by a large margin. Stopped down to f3.5 and it's sharp throughout the frame. I don't mind manual focusing (using Magic Lantern with focus peak and 10x zoom), but it does slow me down quite a bit and prevents me from taking any short of action shot. The kit lens is quite dreadful for what I (try) to use it for, normal perspective landscape shots. Even shooting at f8-f11, the corners are quite soft. I recently borrowed a Canon 17-40 f4 L and it was a good amount sharper than the kit lens. However, my Super Takumar 55 easily beats it at every aperture throughout its zoom range. The S-M-C Takumar 135 f3.5 is a lot like the kit lens. It's usable, but you really need to stop down to f5.6 or f8 for it to be decently sharp. At that focal length and at those apertures, it can be hard to achieve the needed 1/200 second shutter speed to prevent hand shake. More disappointing, however, is its minimum focal distance, which seems to be around 5-6 feet. As such, it's hard to fill the frame with the subject, which is what I'd be using the lens for.
So, what am I looking for? I typically shoot with my 55 Tak and really enjoy it, although it is soft before f3.5. When I use the kit lens, I usually shoot it in the 18-24 mm range. I enjoy that range for landscape, but really like subject separation and high-bokeh types of shots. I pretty much only do nature shots of either landscapes or interesting subjects (like fall leaves, berries, flowers, etc.). I'm looking to spend about $1000 and can go a bit above if needed.
Here's what I'm thinking in terms of potential combos:
1. Sigma 18-35 f1.8 (for landscape 18-24 range and it's extremely sharp for crop)
Samyang 85 f1.4 (sharper, but MF) or Canon 85 f1.8 (for subject separation types of shots)
2. Canon 24 f2.8 STM (for landscape...I'd only be shooting this at f5.6 and above)
Canon 70-200 f4 IS L (for subject separation, great sharpness. Bonus is that I could use this for some wildlife shots)
3. Canon 24 f2.8 STM (again, only would use this at f5.6, but it's a great value for this focal length)
Canon 100 f2.8 IS Macro L (for subject separation and macro, which is a plus)
Other lens that I've seen that are good:
Canon 100 f2.8 Macro
Samyang 135 f2 (looks sharper, but slightly harder to use than Canon's due to MF)
Canon 60 Macro (it's a little too close to the 55 Tak in terms of focal length and I do have extension tubes for the Tak)
I'm open to manual focus only lens, like Samyangs. I do enjoy USM focus, but it's really not required. Obviously, it comes down to what I shoot, but I really want the best lens I can get in terms of sharpness, bokeh (for > 50 mm), and color rendition within my range. I'll make adjustments as needed to my shooting style to make it work.
Notice that I didn't include Canon's 17-55 f2.8 IS or Sigma's 17-50 f2.8 OS lens as I really would only use them for the 17-24 mm range, which makes the Canon a bad value and the Sigma is really too soft in the corners for good landscape shots.
What are your thoughts? Am I overthinking this? I once considered the Sigma 18-35 f1.8 a no-brainer, but realized that I probably wouldn't use it at f1.8-f3.5, so it's not as easy of a decision. I do think that combo #1 is probably the sharpest combo, but I'm intrigued by both the Canon 70-200 f4 IS L and the Canon f2.8 IS Macro L for the zoom range and the macro capabilities. Obviously the Canon 100 f2.8 Macro is a good lens too, but no IS at 100 (160 view on crop) is a little harder to use if I'm not taking strictly macro shots with a tripod. Plus there's not a huge price difference between the two, so the L is preferred in my opinion.
Any advice would be greatly appreciated as I've been thinking about this for a little over a month and have read/watched too many Youtube reviews to count. I'm really at a standstill right now.
Thanks in advance and sorry for the long post!
