Does the Tamron 17 50mm F2 8 still need a 50mm F1 4

If you take portraits, you can't talk about it without a fixed focus......Especially the indoor portrait or something.

50 is equivalent to 75+ mm on a half-frame camera, which is a relatively reliable portrait focal length......A wide aperture can also create a better bokeh effect.........As for the viewing angle, I personally think it's the same ...... as the full 75 headsThere is no difference in perspective relationships.

As far as I know, the Tamron 17 50 can't open the aperture widely, and basically it has to be above f4 to have a better image.

It is best to buy a portrait with a focal length of 85 or more. 50, although the focal length is about 75mm according to the angle of view. But it's actually still a 50mm focal length. It's just equivalent to cropping a big picture and making it smaller...

It is best to shoot portraits with a direct focal length of 85-135mm.

The 17-50 already covers 50 focal lengths, but the aperture is not as large as the prime focus. However, even with a large aperture, there is still the embarrassment of insufficient light when shooting in a room, so there is no need to buy a 50 fixed focus! Of course, the imaging effect is definitely better than 17-50!

Don't buy a 50mm lens; Or add a wide-angle prime focus.

50 is a must, preferably 50

A16 is not good at shooting portraits, and it is also color-cast.

Tenron's lens is very good, but it's not easy to focus, it doesn't feel very comfortable, Canon's EF lens is recommended, Canon's EF lens, in terms of imaging quality has caught up with and surpassed other lenses of the same specification, and at the same time has good versatility, the landlord can consider!

There is not much difference in imaging with the 500D body, and I think it is more important to consider which one to choose in the long run. Whether you are ready to upgrade other lenses, consider the focal length and lens group you need. And with different lenses, the imaging is different.

It can be said that the same lens with different bodies, the effect difference is not obvious. However, one thing must be considered is that the D5000 does not have a body motor, and can only be equipped with a lens group with a focus motor in the future, so the range of choices is relatively small.

2.Tenglong's lens is very cost-effective, at this price, except for fixed focus, there is basically nothing to beat, I have been using this head + d40 body, ordinary travel pats and amateur pats are enough for portraits. The aperture is already very large.

I don't like to change lenses, I prefer to go around the world with one shot.

The effect of the sleeve is definitely not as good as D5000 + Tamron B005. The disadvantage of Tenglong's head is that the focus is a little slow, the capture is a little reluctant, and the other one is easier to get into the dust. 50 I don't think it's much better than the dragon's, and it's very troublesome to change your head.

Yes, D90 with this lens of Tamron is also very harmonious, it still depends on your personal budget, and it is best to go directly to D90.

You have 4 questions, and I'll answer them in your order. Before the answer, there is a question about buying a DSLR camera: as far as SLR is concerned, 1, Canon 500D and Nikon D5000 belong to the same grade of machines, there is no fundamental difference in imaging quality, and it is a good choice to buy any brand. You either buy Canon or you buy Nikon.

2. You know about Nikon, and I still want to advise you to get acquainted with Canon again. As far as you are talking about the Tamron 17-50, this is a standard zoom lens, which can cope with ordinary street sweeping, material shooting, and portrait shooting. The issue of aperture will not be discussed.

3. Your friend's configuration makes sense, but not completely, and the focal length below 50 is lost, and the wide angle is gone. Therefore, under your budget standard of 6000 yuan, I think it is more appropriate to enter a lens like 18-200. From wide-angle to telephoto, when you've saved up enough money, focus on configuring your lens group.

4. Strongly urge you to enter the Nikon D90, which may break your budget, but it is definitely worth it.

Tamron 17-50 has a good reputation, suitable for landscape and humanities, but the pure portrait aperture still can't shoot a better light ratio effect, telephoto either choose fixed focus, or choose 70-200, if you choose 70-300 image quality will disappoint you. I think it's necessary for you to buy a portrait with a large aperture prime focus, which is very attractive in the low-light effect indoors and the atmosphere with a large aperture. The Nikon 50 is not as good as the 50, of course, it depends on whether you have a motor in the body, and the 50 is better if you have a motor.

In addition, for Sigma, 50 and 35 are a head that I have changed my view of Sigma, the previous Sigma is yellowish, and the sharpness is mediocre, the focus is flat, and it is also the king of running Jiao, I have not been optimistic about it, but until I recently saw the review of these two heads, and I bought a Sigma 35 myself, I think the picture quality is unusually good. However, the phenomenon of out-of-focus still exists, and it must be tested clearly when purchasing. If you buy one that doesn't run, you earn.

The following is my Guangzhou Auto Show with Sigma 35**, my photography skills are average, you can click**100% view only to see the sharpness and color,** is the original picture without any later modifications, I hope to give you a reference role, and then evaluate.

Buying lenses is to see your own needs.

If you need a telephoto, buy the zoom, on the contrary, it is the fixed focus, others don't know what you need, I think, the header, the portrait bokeh ability is not very good, and the improvement is not obvious compared to your existing lens, and you really need to buy it again, for your reference.
