Yes, you totally got what I mean in the last reply. I am always amazed to see there are so many Taiwanese good at English.
By the way, sorry I did not notice you got legendary Sigma 50 F1.4 already.
I have sigma 50mm F1.4 HSM also and I love it so much for indoor portrait works.
I have Tamron B005 also and not loving it much for portrait works... >_<"
I have EF 85mm F1.8 USM and love it for outdoor portrait works.
I have Tamron A005 for outdoor portrait works and I fall in love with A005.
I have Tamron A09 for both indoor and outdoor portrait works and A09 is my No.1 favorite.
My best recommandation is still Tamron A09 for portrait works either indoors or outdoors.
- you will need flexible focal length for portraits, try taking a portrait shot with a 1 1/2 years old baby and then you will know what I mean. Or, simply shooting pics of muti-directional moving object will show you how important it is to have flexible focal length.
From your reply to others I can tell you are quite polite but you are so easily influenced by others. That is not a good sign. You would end up buying a lens good for other people but not so good gor your purpose -> taking portrait shots.
Please come back to your purpose --> taking portrait shots on APSC body.
Let me help you to make an well-thought and educated decision on purchasing PORTRAIT LENS.
What you need to do is ask yourself the following questions and spend a little time to do some research on them:
1. appropriate focal length for portrait shots - essential
2. appropriate aperture size or working aperture size for portrait shots - very very essential
3. other benefits that come with lens such as IS USM, or OS HSM, or VC USD. - not really important but a benefit is a benefit.
I will try my very best to guide you through and please do use a dictionary if you have any question.
OK now, I will offer you some of my thoughts on the 3 questions above.
1. So your model or audience loves only "big head doggy" style portrait shots? Give me a break will you?
- Wide angle lens is not good for portrait shots. In fact, although you can use super wide fisheye to take portrait shots; you will find it awefully hard to properly structure your portrait shot with fisheye lens. So, in my opinion, any focal length less then 35mm on APSC body is not really appropriate for serious portrait works.
- Often a praised portrait length is between 50mm to 135mm on FF bodies. Personally I found focal length over 85mm is way too hard to handheld shooting without IS or VC or OS. That is why I don't recommand EF 135mm F2 L to you. We all hand-shake a little bit. Why torture yourself with 135mm without IS VC or OS?
- 50mm and 85mm lens are both great portrait focal length on APSC body. Since you have Sigma 50mm F1.4 on your APSC body then you know what I mean. EF85mm on FF is nearly 135mm on APSC. I use this EF85mm a lot outdoors because I got a lot of light to increase my shutter speed and space between me and my model is great. EF85mm has this incredible bokeh and tight sense of space. I strongly recommand anyone who is interested in portrait should buy this cheap lens. EF85mm has the fastest focus speed I have ever experienced. Second fastest focuss lens is my EF-S1585mm if you want to know.
2. Everyone love big aperture size and in fact people do pay big money for bigger aperture size. However, here are some cruel facts about big aperture size lens.
- Are big or large aperture workable or usable on portrait shots? Try your sigma 50mm f1.4 to shot a portrait shot with model in front of you 2~3 feet away from you and have your model turn her face 45 degree from you. If you use aperture size at 1.4 then you will notice that you will have a one clear eye model on your picture. F1.4 is simply not practical in that condition.
- in real world, photographers in studios often use F5.6 or even F8 to take portrait shot with flash and curtains on. However, it will be a total different story if portrait is taken at outdoors setting. From my own experience, Sigma 50mm works best for me if I position myself 4~5 feet away to take head shots at F3.2~5, 7~9 feet for half body shots at F2.5~8. Trust me, many models including myself feels 50mm on APSC is kindda too close to each other and we do all need some personal space.
3. Everyone welcomes functionality (such as IS VC OS) added to lens to increase successful shooting rate or to increase the pleasure of using the lens (such as USM HSM USD).
However, IS VC OS and USM HSM USD although are great to have but not really factors that produce amazing portrait shots. So, you should select the lens at your own preferential taste.
God, this is getting to be a lengthy reply and I doubt the value of it to you. I will cut it from here.
Go search Tamron 28-75mm on Flickr and look for professional wedding photographers and portrait photographers. You will be amazed of how A09 performs on the hands of professional and professionals do choose A09 for professional works.
Also, please look up EF 85mmf1.8 on Flickr and you will how wonderful 85mm is for APSC bodies.
Remember, and this is very IMPORTANT. Take portraits of your family and your loved ones. Share your portrait works with your family and loved ones. no sigle lens or camara is more important than your family members and in fact they don't care what lens you use but it is you who they care and treasure. My parents always enjoy my twin sons' photo and havie a great time talking about memories from the photo. To be honestly with you, my family never care about what lens I use but rather they do care and enjoy me taking pictures of them and keep memories on pictures for them.
A smile from your loved one: Priceless...
