Will the Tamron SP AF 17-50mm f/2.8 need an adapter to fit on the 7D?

If any of you have experience with this lens, how does the manual focusing work for video? Some reviewers said that they returned the lens because of manual focusing issues.

What mount am I looking for and what adapter?

So I just had a look through EBay at these lenses. I can't find any compelling reason to buy one. The only lens faster than F2.8 was the range of 50/55mm lenses and they were more expensive than the Nikons.

So the problem for me is this:

The lenses are slow. I can get Nikon glass at F2 or faster for the entire cinematic range.
They aren't any cheaper. This is what really surprised me.
I don't think the glass is any better.
I'd have to buy new adapters (both to Nikon and Canon).
I'd have to buy step up rings for my current filters.

I'm sorry, and I was curious. But I can't see how this would make any good economic sense for me. If I had an M42 body maybe...

Agree about cost, not so sure about speed. 10 years ago, these lenses were peanuts. I built my collection a few years ago, and since then most or all of them have doubled in value. Expensive or not, they are a good investment.

Wow, slow is a bit harsh. There is no 85mm f/1.4 to match the Nikon (I have my heart set on a Samyang), and there is a gap below 35mm for fast takumars (I have a nice Vivitar 28mm f/1.9 for that) but otherwise there are options.

The 35mm f/2 is a great lens, if not the best Takumar. The 85mm f/1.8 is very special. I have the 85mm f/1.9, and it is also a fine lens. As you said there are the 50mm varieties. The f/1.4 SMC is legendary, nuff said. Some say the 50mm f/1.2 is the finest, but it is super rare. Less rare is the 55mm f/1.8, which is a VERY underrated lens, believe me. Especially considering you can still get it for pennies.

Beyond f/2 you have the 135mm f/2.5, which is another GREAT lens. Finally the 105mm f/2.8 is worth a mention and has its uses.

Agree. Maybe worse. Depends on your preference, but I promise you Takumar images have a special character which is exciting. Also, although it doesn't necessarily make your video any better, the build quality and focus action of these lenses is a dream to work with.

Yes the best way is to shell out on adapters and rings for each lens, which does mount up. Saying that, M42 adapters open up other possibilities for yard sale finds. I have a 15 blade 'bokeh monster' 135mm f/2.8 Pentacon, which is just superb and cost £40.

You are of course correct, but I never let economic sense interfere with my lens buying addiction. I still plan to buy a Nikkor.

My comment of them being slow should not be extrapolated to the entire series of lenses. My comments were ONLY directed at the lenses I found currently for sale on EBay. Nearly all of the lenses were F3.5, the only exceptions being a 105mm F2.8, and the fast(er) 50-55mm lenses. I have zero interest in F3.5 glass.

Much of this reads like Nikon's offerings. And I suspect that the lens designs of the day were all quite similar. However, I'd imagine that Nikon was outselling Pentax 10:1 or 20:1 at the time. I was shooting for the newspaper back then and I don't know a single photographer who had a Pentax. It wasn't until I was doing portrait work at University that I finally ran into a Pentax photographer and he had a 6x7 that I fell in love with.

I need to see some images from these lenses on a 7D or similar. I need a couple of portrait lenses (85mm, 105, and 135) and am interested in trying a few things out. But it looks like it will be a $300-$400 per lens experiment, and I am not willing to put forth that much cash without a VERY good reason. I KNOW what I am getting with the Nikon glass in those focal lengths. The Nikon 85mm and 105mm are world wide legends and are still used all over the world by 35mm portrait photographers.

See this comes back to the problem for me. At F2.8, I can put a quality zoom lens on. For stills work, the prime would certainly be better, but for video work, the immediacy of the zoom essentially outweighs the slight resolution advantage of the prime. Now if that prime were F2, then we might have something to talk about.

There are a great many good ones to choose from. Some tack sharp wides, to some creamy portraits, to some insane longer glass. I've got my eye on the 200mm F2 for some of my sports video this fall. Night video demands faster glass.

I don't see color balance problems using the Cokins, lots of people are critical of them for being resin etc, but I have had good luck using them. I regularly use the 4x and 8x and polarizing filter stacked together, I have three filter holders each with a different filter thread so I can use the filters on my Nikkor lenses (52mm) and my Canon 50mm 58mm and Canon HV30 43mm.

I also notice on the 7D and my Nikon D300 that the sensor has a slight magenta color cast, which maybe a factor in color balance.

Same.

Pentax's heyday was late 60's to early 70's. After about 1975 the market share dwindled, but they innovated much of the SLR technology. Nearly all the classic Takumar glass is pre-1975.


Nah, ignore those prices. 'Buy now' and 'best offer' ads are worth ignoring in favour of auctions. There seems to be a fashion for listing Takumars at stupid prices these days, but dig deeper you will see their true price. The following links are to 'completed items' in order to show what they really go for.

By the way, in no way am I comparing these to the Nikons you list, which are without doubt more desirable than the examples I offer, but in my opinion, the difference in desirability is not reflected in the difference in price. Takumars are still a bargain and are great for video.

Agreed. If I had the money, it would be L series zooms all the way, especially on a professional shoot. But I would still keep my Takumars for creative purposes. They are just different. Modern lenses are optically superior in a technical sense, but sometimes that L lens might be too clinical and contrasty for what you want, or perhaps you are looking for a particular character of flare. Of course, you can do most things in post, but it's not quite the same, and it's not as much fun.

Thank you for this post! At thos prices, I'm willing to take a risk on one of these pieces of glass. I'll try to see what pops up in the next couple weeks, and buy something. A 50 if nothing else, because those are very inexpensive.

I am used to looking at the buy it now prices because the Nikons usually bid right up to that. If I can start snagging some of these faster primes at around $100 a piece, and they look good, I am on board.

For the stuff I shoot, I prefer the lenses that have a bit more character to them. Keeps me from having to attach diffusion in front of the lens, or soften things after the fact. I love the character of the Nikon glass pre- 1975. My 300mm Nikon from 1972 is one of the prettier pieces of glass I've used, but has very limited use for me because it's somewhat slow.

And "L" glass doesn't hold much for me. Never has. But I've never been an autofocus fan. And I abandoned Canon after my first EOS cameras... long before digital hit the scene.

Thanks again for this. I'll update in a few weeks with what I bought and how it's working. I've got some model photography to do next month and one of these 85s is going to be perfect.
